; File: PatchIIciROM.a
;
; Contains: patches for the ROMs first shipped in a Macintosh IIci ($067C)
;
; Copyright: © 1985-1991 by Apple Computer, Inc., all rights reserved.
;
; Change History (most recent first):
;
; <146> 12/2/91 SAM Using official boxflag equates now.
; <145> 12/2/91 pvh Added cache flushing to fixup patch table code.
; <144> 10/28/91 SAM/KSM Rolled in Regatta Changes.
;
; Regatta Change History:
;
; <15> 8/30/91 SAM Added a check for Tim boxFlag to the code that changes boxFlag
; from boxTim to BoxTimLC. This prevents non-Tim/TimLC machines
; using the TERROR ROM with power mgrs and no-FPU being identified
; as a TimLC.
; <14> 8/30/91 SAM Added a check for an FPU in the previous backpatch patch so it
; will not install on machines without one.
; <13> 8/29/91 SAM Added a check for Zydeco to the "should we remove (ie override)
; the PACK 4 & 5 SANE rsrcs in ROM" check. (CCH) Added a patch to
; _FP68k for 030 TERROR machines that will not allow _FP68k calls
; made from ROM to be backpatched.
; <12> 8/15/91 SAM (RMP) Added v32SetHandleSize patch. SetHandleSize calls the same
; common routine that v32SetPtrSize calls, a32SetSize. SetPtrSize
; was patched earlier to fix a bug in a32SetSize <121> but
; SetHandleSize was never patched.
; <11> 8/9/91 SAM Moved the disposal of the Gestalt tables made by ROM to after
; the reinstallation of Gestalt from disk. This prevents crashes
; caused by someone calling gestalt after the old tables have been
; trashed prior to the new table's creation.
; <10> 8/8/91 SAM (eva) patch level 4 autovector pointed to by vbr, not just the
; zero-offset cuz when VM is running VBR ­ 0.This routine is a
; patch to the _VM trap. It fixes a bug in the Terror ROM which
; occurs when the page the stack is marked uncacheable in the MMU
; tables, then a subsequent PFLUSH'd is executed with data still
; in the cache.
; <9> 8/7/91 SAM Moved the boxFlag slam before Gestalt. Brainfade.
; <8> 8/6/91 SAM Added a check for TIM LC that will stuff the correct boxFlag
; into BoxFlag if we're running on a TIm LC. Gestalt's private
; storage allocated by the ROM version is disposed of prior to
; reinstalling gestalt from the disk.
; <7> 8/5/91 SAM (eva) fix patch <6>: Port B dispatcher fixed to call serial
; service routines and to have same number of bytes before the rts
; so that async serial driver Rx and SCx patches (which fiddle
; with return address on stack) return to the proper place.
; <6> 7/30/91 SAM (eva) fix the Farallon MacRecorder bug by modifing patch to test
; for port A RxChar and loop back only if we are servicing a channel
; A interrupt. For port B we just jump to service routine like ROM
; code.
; <5> 7/29/91 SAM (eva) patched SCx interrupt handler to fix the StyleWriter bug.
; On faster machines we are able to send out a byte fast enough
; after the TBE bit in RR0 gets set that the byte gets written
; before the TBE interrupt is generated. Instead of just not
; generating the interrupt, the SCC goes ahead and generates it,
; but changes the interrupt source code to read 'no interrupt'
; instead of 'TBE'. This 'no interrupt' code is identical to the
; 'Special Condition on port B' code, which was the source of our
; problem. Fix is to just exit SCIntHnd if no special condition
; bits are set.
; <4> 7/17/91 SAM (EH) Added Lvl4 irq patch to improve serial performance.
; <3> 6/30/91 SAM Conditionalizing the SCSI Chaining Bus Error handler for non
; C96.
; <2> 6/14/91 SAM Removed the GestaltHardware patch in favor of the real code in
; GestaltFunction.a. Fixed a check for an unallocated Palette Mgr
; handle in the InitPalettes Patch. (RMP) Added the IIfx IOP irq
; MPW fix to the set of Eclipse fixes. (bg) Changed the Egret
; "CheckPacket()" patch to allow the full
; range check of possible pseudo-commands.
; <1> 5/15/91 SAM Split off from 7.0 GM sources. Added code to use PACK 4 & 5 from
; disk on IIciROM machines that are not TERROR A7 or newer. Do
; not save GestaltÕs old Logical mem size across PtchInst 5
; (which is Gestalt) cuz the old number is wrong.
; 7.0 Change History:
;
; <143> 9/18/91 JSM Cleanup header, donÕt include InternalOnlyEqu.a (already in dump
; file).
; <142> 8/30/91 DTY Define isUniversal here since itÕs no longer defined in
; BBSStartup. This file used to use {Defs32}, so isUniversal is
; defined to be 1.
; <141> 6/12/91 LN added #include 'ROMPrivateEqu.a'
; <140> 6/12/91 LN removed #include 'HardwareEqu.a'
; <139> 4/12/91 dba ewa: add magic signature to Time Manager task used to implement
; VBLs; the signature will prevent VM from deferring the task
; <138> 4/8/91 eh Fixed bug in iop serial driver that was causing bad printing to
; Imagewriter. Actually, it was two bugs. CTS interrupt disable
; code had a bad branch and the IOP timer never got kickstarted.
; <137> 4/5/91 eh Fix to Serial driver SerSetbuf call. Missed one place in <135>
; that sign extended a register.
; <136> 3/28/91 SAM As per DarinÕs request, I have added a TestFor SCSI96_1Exists
; before the Quantum 7.9 ROM fix from the Regatta deltas (without
; forRegattaCPUs).
; <135> 3/17/91 eh Serial driver status calls 9 and $8000 now return hardcoded
; driver version instead of getting it from DCE. This obviates the
; need for the linked patch to _Open to patch the version number
; in the DCE, a fix which was causing FileShare to crash. Also
; fixed bug in IOP SerSetBuff (control 9) call -- was sign
; extending a register unintentionally.
; <134> 3/8/91 DFH VL,WS#DFH-910308a: Fixed SetEntries patch to not chew on a2.
; This led to crashes, such as in AfterDark.
; <133> 3/4/91 dba dty: get rid of SysVers checks
; <132> 2/26/91 DFH csd,WS#910226a: Fixed bug in ptchPMgrExit where it assumed that
; graphics has been initialized. Bug introduced by change <124>.
; <131> 2/25/91 gbm csd, #83338: Fix the fix to Gestalt. Save the original Gestalt
; globals pointer, and put some important (but hard to figure out)
; data back in it after the RAM copy installs
; <130> 2/21/91 gbm csd, #83338: Start including the Gestalt ptch even on ci ROMs.
; <129> 2/21/91 eh (djw) Fixed bug in serial driver that was preventing use of one
; port when Nike was printing on the other.
; <128> 2/19/91 gbm csd, #Go5 approved: Make sure _MemoryDispatch is NOT implemented
; on machines without PMMUs.
; <127> 1/29/91 eh (djw) Fixed a bug in the External Status interrupt handler. On
; port A we crashed on receiving a break if a read was pending
; because we weren't getting the .Ain DCE ptr properly. Now we get
; the DCE ptr directly from the Unit table, just like for port B.
; <126> 1/25/91 eh Fix iop serial driver to: time out an waiting for all-sent in
; the close, and to disable HWHS properly when external clocking
; is set.
; <125> 1/19/91 eh (djw) Patch async serial bypass driver headers to insert
; signature longword used by linked patch to Open in Serial
; Patches.a . Added signature longword before already patch IOP
; driver headers.
; <124> 1/18/91 dvb Don't restore color environment if it hasn't been changed.
; Modify SetEntries to mark flag in QDSpare.
; <123> 1/14/91 eh (djw) Added external clocking support for the NIke printer to
; the Async Serial Driver.
; <122> 12/19/90 djw (ewa) Patch ROM SCSIDispatch to the ROM SCSIDispatch to resolve
; a VM patch conflict.
; <121> 12/19/90 TL Fixed an old bug in setptrsize for old time sake, in calls
; between relocRel, the tag is restored in the old block, instead
; of the new block location. And also discard flag when two block
; sizes are identical.
; <120> 12/19/90 dvb Don't draw windowframes after InitGDevice. Removed some
; duplicate code between PatchIIciROM.a and PaletteMgr.a.
; <119> 12/15/90 djw (jwk) Add SCSI Mgr support for Quantum 7.9 ROM problem by
; replacing blind write routine
; <118> 12/14/90 dnf (jsm) Turn all patches on ExtFSHook off for 7.0 since they have
; been moved to LaterFileMgrPatches.a
; <117> 12/14/90 SMC Patched DisposeAppPalettes via PMgrExit to use ApplZone->bklim
; instead of HeapEnd to determine if palette is in the application
; heap. Also, patched PMgrExit to only throw away palettes if app
; is front process. With DFH.
; <116> 12/14/90 dba <JDR> get rid of VMCalls.a
; <115> 12/6/90 BBM (dba) Protect the Come-from patches. Eleminate TextFont patch to
; the MDEF, as the MDEF in ROM is not used anymore, RomOverride at
; its best.
; <114> 11/15/90 JSM <bbm> Move come-from patch on _OpenCPort inside NewGWorld to
; QuickDrawPatches.a.
; <113> 10/31/90 dba & csd; kill 8¥24 GC loading code for 7.0 (StartSystem.a does it
; now)
; <112> 10/22/90 JJ Rex V8: Change VISAChipBit to V8ChipBit.
; <111> 10/22/90 JJ Rex V8: Change all box flag references to use boxMacLC. Get rid
; of boxElsie and boxElsieV8.
; <110> 10/9/90 SAM Updated the AppleTalk _Open patch so that it stuffs PortNotCf
; into ioResult if SPConfig >= 2.
; <109> 9/26/90 SAM Redoing the patch to Open that fixes the .MPP crash.
; <108> 9/25/90 KIP Change Sound Mgr. to a linked patch.
; <107> 9/18/90 SAM Added changes from SixPack code review (search for <107>).
; Removed EclipseNOPs (as per BGs request). Fixed the last of the
; build warnings for this file (rah).
; <106> 9/15/90 DC added GetGray
; <105> 9/15/90 GMR Fixed Gestalt parity routine to set good parity before testing
; the byte with bad parity, so the RPU interrupt would not cause
; bad data to be stacked.
; <104> 9/5/90 EH Removed duplicate declarations for PollProc, Pollstack, and
; HiIntMask from EgretMgr patch <101>.
; <103> 8/31/90 SAM Adding fix to ReallocHandle patch that checks to see if SysZone
; = AppZone and if so it only checks the current heap then jumps
; back to ROM. Added a patch to open so that it clears out the low
; nibble of SPConfig when the .MPP driver is opened. Made
; GestaltHardwareAttr recognize Visa/V8.
; <102> 8/29/90 GMR Fixed Gestalt parity check on FX so it does not destroy A4 (this
; reg needs to be preserved throughout patches and inits!)
; <101> 8/22/90 SAM Adding a series of REgret patches & a SANE ptch (search for
; <101> for more explicit descriptions).
; <100> 8/20/90 dvb Remove "DrawGrayishText"

; real this time.) Also deleted an INIT 18 patch for Darin.
; <95> 8/13/90 JWK NEEDED FOR SIXPACK: Added NuBus and Serial Gestalt selectors.
; <94> 8/11/90 PKE NEEDED FOR SIXPACK: Fixed bug in previous revision - (per KIP)
; ptch 3 must load before ptch 23 so SoundMgr globals are
; initialized!! Was causing ci & fx to hang during boot.
; <93> 8/10/90 SAM Made ptch 3 (7.0 Sound Mgr) load on all IIciROM machines. It
; used to *not* load on Erickson/Elsie.
; <92> 8/8/90 SAM Changing DispatchHelper & ProcHelper into an old style ptch.
; ¥¥¥--> Temporary <--¥¥¥ Remove when the Sound ptch get converted
; into an Lptch.
; <91> 8/7/90 PKE Fixed the SixPack build by adding an eclipseDebug conditional
; around a BRA.S. Build was broken because BG changed BBSStartup
; to turn on eclipseDebug for Mac32 (which applies to this file),
; so EclipseNOPs are expanded and a branch went out of range.
; Also, altered the previous comment to say needed for SixPack.
; <90> 8/5/90 PKE NEEDED FOR SIXPACK: Moved installation of Script Mgr ptch 39 and
; 27 to Mac and A/UX section of install code (was formerly for Mac
; OS only). Search for <90> to see changes.
; <89> 7/30/90 SAM Added Egret TickHandler patch so it doesnt loose time while IRQs
; are off.
; <88> 7/30/90 dnf Remove installation of ptch 18 (File Manager) and ptch 6 (Btree

; ptchInst 16 since PrGlue is a linked patch
; <86> 7/21/90 BG Added EclipseNOPs for flakey 040s.
; <85> 7/20/90 CSL Needed for SIXPACK: Totally replaced Memory manager routine
; a32SetSize, patch <68> only replaced part of a32SetSize and is
; not sufficient.

; <73> 7/2/90 DTY Remove ptchInst 21 since Resource Manager extensions are now in
; a linked patch.
; <72> 6/28/90 DDG NEEDED FOR SIXPACK: Put in a fix for egret. Now the
; _ReadDateTime call does not actually call the clock chip. It
; simply reads the low mem global (Time) and returns that. This is
; OK, since Time is automatically updated. This fix only happens
; on Elsie and Erickson.
; <71> 6/25/90 DTY Removed ptchInst 9.
; <70> 6/25/90 KON Remove rSwapMMUMode macro 'cause it's in QDHooks.

; <59> 5/2/90 CCH Fixed bug in parity routine for pre-IIci machines with IIci
; ROMs.
; <58> 5/1/90 CCH Added Scrolling throttle and Square menus to misc selector.
; <57> 4/22/90 csd commented out the installation of SCSI DMA so we stop trashing
; hard disks on the IIfx.
; <56> 4/19/90 NB Add PrGlue to the PtchInst list (#16). It's already on all other
; machines
; <55> 4/18/90 DDG Rolling in the ReallocHandle patches from the sys6 sources.
; <54> 4/16/90 DDG Rolled over changes from the split off sources including: a

; which no longer exists in this PTCH.
; <50> 3/26/90 PKE Moved definition of symbols that control Script Mgr patch and
; 'ptch' installation into ScriptPriv.a. Renamed symbols and added
; some.
; <49> 3/23/90 NC Added ptch 43 for System 6.0.6 on up. This is for Sound.
; <48> 3/20/90 DDG Added code to not install patch 3 on Ericksons and above for
; Sys607 and above.
; <47> 3/12/90 DVB Fix PMgrExit so that ExitToShell doesn't crash!
; <46> 3/8/90 JAL Took out include of QuickEqu.a because it is already in
; StandardEqu.d.
; <45> 3/4/90 PKE Changed _UprText to _UpperText to match new Traps.a.
; <44> 3/1/90 GMR Fixed bug in Gestalt parity check for Zone-5, where longword was
; not being written back with good parity after each SIMM check.
; <43> 2/28/90 GMR Added include of EgretEqu.a to fix system disk build.
; <42> 2/28/90 PKE For 7.0, moved Script Mgr ROM patches into ÔptchÕ 39: patches to
; _Pack6 and _GetIndADB, fixes to String2Date/InitDateCache,
; installation of some new vectors, and the change to SwapIcon.
; For all of these except the SwapIcon change, the code is still
; here but conditionalized differently (in case we need it for
; 6.1).
; <41> 2/26/90 EH Rewrote <8.7> to use patch macros. Added on patch for 68000 IOP
; Serial Driver read bug.
; <40> 2/23/90 DVB PMgrExit no longer clears the windowlist.
; <39> 2/22/90 PKE Replaced obsolete _LwrStringToUpr opword with _UprText. Removed

; longer need it.
; <38> 2/21/90 JS NEEDED FOR 6.0.5: SetDepth also takes a mode
; <37> 2/16/90 EH Fixed CTS status bug and low baud rate bug in IOP Serial Driver.

; IOP Serial Driver DMA hang bug.
; <32> 2/14/90 CCH NEEDED FOR 6.0.5 - Made sure external cache on Zone 5 does not
; interfere with the check to see if parity RAM is installed.
; <31> 2/13/90 SMB NEEDED for 6.0.5 - Added installation code for ptchGetLRPosition
; and ptchPixelWidths for TextEdit.
; <30> 2/9/90 EH NEEDED FOR 6.0.5: Patched Level4SccIopInt to set flags such that
; all the IOP completion routines be called immediately from the
; IOP Manager, rather than be run as deferred tasks. This, so we
; don't break Timbuktu/Remote.
; <29> 2/2/90 JWK NEEDED FOR 6.0.5: Changed SCSI Mgr bus error handler to allow
; chaining to previously installed handler if a non-SCSI bus error
; occurs.
; <28> 2/2/90 GGD NEEDED FOR 6.0.5: Modified the Deferred Task Manager to enable
; interrupts when returning just so QuickMail servers will

; ¥ Add install code for TEFindLine patch. ALSO: Updated
; conditionals so SS-6.0.4 changes go in 6.0.5 as well as 7.0.
; Cleaned up the BBS header and eliminated the EASE header.
; <5> 1/3/90 BAL NEEDED FOR 6.0.5: Fixed Zero width character problem in

; <8.7> 12/14/89 EVA NEEDED FOR 6.0.5 Fix SerialDriver.a patch to check SCCIOPFlag
; instead of PRAM to see which driver to load
; <8.6> 12/11/89 smb NEEDED FOR Scripts 604 AND (6.0.5 <= SysVers < 7.0): added
; installation code for TE routines CaretInsideRun,
; InvrtRectangle, SetKeyboard2Font.
; <8.5> 12/8/89 PKE NEEDED FOR Scripts604 AND FOR (6.0.5 <= SysVers < 7.0): Patch
; LwrString to handle 2-byte chars via Transliterate (yuck). For
; 7.0, we do this elsewhere.
; <8.4> 11/29/89 GGD NEEDED FOR 6.0.5: Re-Enabled the SANE optimization to bypass the
; Package Manager which never made it into 6.0.4. Fixed bug
; StripAddress that caused it to sometimes not strip when in a
; interrupt handler. Modified ADB auto/srq polling to not poll
; device addresses that are not in the device table. On OSS based
; machines, install a time manager task to simulate a 60.15Hz
; pseudo VBL because the OSS generates a 60.00Hz interrupt which
; is the wrong frequency.
; <8.3> 11/28/89 dvb Fixed bug in PMgr Zaplinks by working over pmgrDispatch. Also
; fixed bug in dispatch.
; <8.2> 11/22/89 EMT NEEDED FOR 6.0.5: Added humane scrolling.
; <8.1> 11/21/89 smb Added installation code for TE routines ptchGetWidth and
; ptchGetRLPosition.
; <8.0> 11/17/89 PKE Tail patch on _GetIndADB to fix Script Mgr SwapKybd routine,
; which cleared ADB keyboard driver dead state as a word: should
; be a long.
; <7.9> 11/10/89 KON PTCH'ed GetNewCWindow so when a palette with the same ID as the
; window exists in the resource file, the palette is attached to
; the window.
; <7.8> 11/6/89 PKE NEEDED FOR 6.0.5!! Bug fixes for InitDateCache and String2Date
; needed for HyperCard. InitDateCache: Fixed CopyArray to use
; correct register (A4) for source pointer, and to initialize all
; relevant bytes of length register (D0). String2Date: if first
; relevant (i.e., day or month name) alpha token is a month name,
; we now search the day name list if we find another alpha token
; (fixes BRC #54946). Rearranged Cache structure to fix invalid
; use of month/day name index.
; <7.7> 10/12/89 smb Moved TextEdit patches to TextEditPatchIIciROM.a. Fixed bug in
; old highlighting code that I introduced accidently (changed
; move.w -> move.l).
; <7.6> 10/11/89 CCH Added INCLUDE of "MMUEqu.a"
; <7.5> 10/11/89 CCH Set up MMUType if not already initialized.
; <7.4> 10/6/89 JSM Removed SnarfMan 'ptch', now PACK 13.
; <7.3> 10/5/89 CCH Changed an ORI to a BSET in gestaltAddressingModeAttr patch, and
; added installation of it.
; <7.2> 10/5/89 smb Added old highlighting code for TextEdit for HyperCard
; outlining.
; <7.1> 10/5/89 EVA NEEDED FOR 6.0.5!!! Fixed bug in async serial driver Ext/Stat
; int handler
; <7.0> 10/4/89 smb Fixed 6.0.4 build by moving around some of my conditionals due
; to dependencies! Fixed TEInit to set TEDoText like it used to.
; Cleaned up TEOutlineHilite. Fixed caret display for outline
; highlighting.
; <6.9> 9/29/89 CCH Added patch for gestaltAddressingModeAttr selector to add
; gestalt32BitCapable attribute. (version 6.8 breaks 6.0.4 builds,
; so I just tested on bigbang - because alpha 0 is in two days,
; thats why)
; <6.8> 9/29/89 smb Added patches for TextEdit for TEFeatureFlag, SetFont2Keyboard,
; and fixed CursorMovement for double-byte characters.
; <6.7> 9/27/89 EMT Fixed 6.2 to use Lea rather than LeaROM for RAM address.
; <6.6> 9/26/89 CVC Added PPC Toolbox as a 'ptch'.
; <6.5> 9/25/89 EMT Added ptchs 18, 6, 29.
; <6.4> 9/19/89 RLC Add Balloon Help (ptch 28) to this file.
; <6.3> 9/18/89 BBM Install resource manager extensions, ptch 21
; <6.2> 9/18/89 PKE For 7.0, patch Script Manager internal routine SwapIcon to use
; new 'kscn' resource type instead of 'SICN'.
; <6.1> 9/17/89 PKE Decided to patch out GetScript/SetScript entirely in ptch 27, so
; we no longer patch them here (see 5.9). Also, for 7.0 we now
; install the Script Manager's Gestalt function in ptch 27 instead
; of here (see 2.5).
; <6.0> 9/12/89 EMT PaintOne patch (3.7) nukes the layer manager. Only use on pre
; 7.0 systems.
; <5.9> 9/6/89 PKE Patch Script Manager GetScript/SetScript routines to support
; additional font info verbs for 7.0, and set up this font info in
; Roman ScriptRecord. Set new sVectCallInterface vector. Redo
; Script Manager version setup, using new smgrVersPTCHRom equate.
; <5.8> 9/5/89 jwk NEEDED FOR 6.0.5: Turn on NewSCSI in ROM if on F19.
; <5.7> 9/4/89 PKE Install Script Manager 7.0 extensions, ptch 27. Set Script Mgr
; version for 7.0.
; <5.6> 8/31/89 JSM Added SnarfMan support.
; <5.5> 8/30/89 smb NEEDED FOR Scripts604 and Big Bang! Bug fix in ptchTEFindWord
; (fixed word dragging bug and now uses old FindWord code when
; RecalLines calls. Also added ptchMeasureWidth to fix a
; hilighting bug at line ends when the line direction is RL on a
; system that is normally LR (ie - Roman, Kanji, etc.)
; <5.4> 8/28/89 PKE For 7.0, initialize additional Script Mgr vectors for
; SMgrCalcRect and SMgrInitFonts.
; <5.3> 8/27/89 PKE NEEDED FOR Scripts604, 6.0.5: Bump Script Manager version for
; Scripts604 or SysVers > $604, since IntlForce bug fix (4.5) is
; installed.
; <5.2> 8/22/89 PKE NEEDED FOR 6.0.4: (really dba) Tail patch to TextFont which
; fixes an MDEF bug in calculating the icon height. Replaces
; GetResource patch in 3.7 which attempted to fix the same
; problem.
; <5.1> 8/21/89 PKE NEEDED FOR 6.0.4: Really put in 4.1, which was only present as a
; comment until now (although it existed on Fiction sources).
; <5.0> 8/21/89 PKE NEEDED FOR 6.0.4: (really CSD) Fixed MDEF 3.7 patch (again. Last
; time, right?) to load #$00200020 into D1 when appropriate
; instead of jumping back into ROM at the same place for both
; cases cicn found and cicn not found.
; <4.9> 8/21/89 PKE NEEDED FOR 6.0.4: (really dba) Changed MDEF patch 3.7 to load A0
; with the right value instead of preserving its value.
; <4.8> 8/21/89 PKE NEEDED FOR 6.0.4: (Per CSD) Correct ROMNoColor address in MDEF
; patch (part of 3.7).
; <4.7> 8/21/89 PKE NEEDED FOR 6.0.4:
; ¥ (per dba) Only re-load the standard clut into QDColors if
; QDColors exists; this is so that A/UX will work
; ¥ Conditionalize 4.5 for Scripts604 OR (SysVers > $604)
; <4.6> 8/21/89 PKE NEEDED FOR 6.0.4!: Patch RelString,UprString,CmpString to
; re-introduce the bug in which "`" is converted to uppercase as
; "a". This is necessary to prevent HFS problems, since existing
; disk catalogs use the old, buggy sorting. Also remove SANE
; optimization (2.0); breaks Excel.
; <4.5> 8/21/89 PKE NEEDED FOR 6.0.4 SCRIPTS BUILD, 6.0.5: Extend Pack6 patch to fix
; a problem in LwrString,CharType,Transliterate,FindWord. These
; routines should save the IntlForce flags then clear them before
; the IUGetIntl call, restoring the flags afterward. This is so we
; get the itl2 tables for the correct script (instead of the
; tables for the system script).
; <4.4> 8/21/89 PKE NEEDED FOR 6.0.4!: Fixed accidental deletion of INCLUDE
; 'VideoPatch.a' in (4.3).
; <4.3> 8/21/89 PKE NEEDED FOR 6.0.4!!: Patch Pack6 to fix me-too problem with
; pointer to unlocked handle in Transliterate; affects Roman
; system (this problem looks familiar; did I dream that I already
; fixed this one?).
; <4.2> 8/18/89 smb NEEDED FOR 6.0.4: Another unlocked handle problem!
; AAAARRRRRGGGGHHHHHH! (See ptchOnSameLine below)
; <4.1> 8/18/89 DAF FOR 6.0.4 BUILD - Fixed a bug on non-CLUT devices in the
; SaveEntries trap on Aurora
; <4.0> 8/16/89 dba NEEDED FOR 6.0.4: InitProcMenu bug fixed: MBDF ID was not put in
; MenuList if MenuList was already allocated (InitMenus already
; called)
; <3.9> 8/15/89 prp Added Alias Manager and Folder Manager support.
; <3.8> 8/15/89 smb NEEDED FOR 6.0.4: Fixed some problems in my patch code for the
; bad pointer bug.
; <3.7> 8/15/89 dba NEEDED FOR 6.0.4:
; ¥ Shortened the SetWin/CtlColor patch by returning to ROM earlier.
; ¥ Patch PaintOne to do nothing if WWExist is non-0.
; ¥ Patch OpenCPort so that the current port is saved across
; NewGWorld.
; ¥ Patch GetResource so that GetIconSize in MDEF does not trash A0.
; ¥ Moved VideoPatch.a so that it does not happen on A/UX.
; ¥ Re-load the standard clut into QDColors so that the green channel
; is fixed
; <3.6> 8/14/89 djw NEEDED FOR 6.0.4: Fixed bug in slot mgr in pInitEntry routine.
; When calling _InsertSRTRec, and the sRsrc has a refnum
; associated with it, _sFindDevBase has bad spId.
; <3.5> 8/13/89 BAL NEEDED FOR 6.0.4: Added tail patch to InitPalettes to defeat
; spurious ExitToShell patching code (leftover from JP builds).
; (dvb really)
; <3.4> 8/11/89 smb Finally rolled in patches for a bad pointer bug (#51602) and an
; up & down arrow keys bug (#51961). See comments below.
; <3.3> 8/11/89 djw NEEDED FOR 6.0.4: Cleaned up file by deleting old comments,
; adding new comments, laying out patches in a "prettier" and more
; orderly format. Added A/UX runtime conditional check for
; Mac-only patches. Moved patches <2.4> and <2.7> to Mac OS only.
; Modified slot manager calls in patche <2.1> as per code review.
; <3.2> 8/9/89 CCH NEEDED FOR 6.0.4: Added patch to gestaltQuickdrawVersion to
; return two digit versions.
; <3.1> 8/8/89 smb NEEDED FOR 6.0.4: Reverted TEFindWord patch since the previous
; patch introduces an uglier bug that won't be fixed now. Also
; added gestalt function for TE.
; <¥3.0> 8/8/89 dba RealityÕs hard disk was full! Try submitting again.
; <3.0> 8/8/89 dba NEEDED FOR 6.0.4: added Menu Manager patches; InitProcMenu patch
; because it simply didnÕt work; MenuSelect patch to reinstate
; WaitMouseUp check
; <2.9> 8/8/89 PKE NEEDED FOR 6.0.4: In gestaltScriptMgr function, if gestalt
; selector is undefined, just leave gestalt result alone.
; <2.8> 8/8/89 smb NEEDED FOR 604: Added more TE patches for Aurora!
; <2.7> 8/7/89 GGD Changed SIntInstall again, to leave $FF as highest priority, but
; reverse handling of equal priorities. Modified to use less
; space. Changed GetBoardROM from <2.4> to be a ROM Offset,
; instead of absolute ROM address.
; <2.6> 8/6/89 DAF FOR 6.0.4 BUILD - Added TFB video card driver override for boot
; screen. This is the same code as is included in PatchIIROM.a
; (VideoPatch.a)
; <2.5> 8/5/89 PKE NEEDED FOR 6.0.4: Add Gestalt function for Script Manager,
; install corresponding Gestalt selectors.
; <2.4> 8/4/89 djw NEEDED FOR 6.0.4: Deleted patch <1.3> (no longer needed). Added
; code to re-init board id's in slot pram (fixes a bug in Aurora
; in InitPRAMRecs).
; <2.3> 8/2/89 EVA (forgot to) include hardwareEqu.a and SlotMgrEqu.a
; <2.2> 8/2/89 EVA FOR 6.0.4 (and above) Patched _SIntInstall to reverse slot
; interrupt queueing order
; <2.1> 8/1/89 CSD FOR 6.0.4: Added patch to suppress appleshare arrows on 32-bit
; video cards.
; <2.0> 7/26/89 GGD NEEDED FOR 6.0.4 Added SANE optimization to bypass the package
; manager
; <1.9> 7/25/89 DAF FOR 6.0.4 BUILD - Fixes for SetWinColor, SetCtlColor in 32-bit
; mode
; <1.8> 7/25/89 smb NEEDED FOR 6.0.4: Added TextEdit patches for Aurora.
; <1.7> 7/3/89 NJC Sound Manager Extensions (ptch 23) rolled in for real.
; <1.6> 6/21/89 NJC Added a ptchinst 3 to if it wasn't already there and added in a
; commented-out ptchinst 23 for the sound dispatcher,DJ, and S.M.
; enhancements.
; <1.5> 5/31/89 CEL Only defined Spline_Font variable if it is undefined - makes it
; easier to build test 6.0.4 systems
; <1.4> 5/22/89 AG Fixed my mistake in gettrapaddress call
; <1.3> 5/21/89 AG Remove NEW SCSI manager trap (A089)

; Window manager patch
;
; This patch corrects a bug in SetWin/CtlColor in 32-bit addressing mode. These routines
; (which operate on identical data structures) can accept a colortable whose ctSize=-1
; which allows an application to specify that the wcTable be set to the default color
; set (via a copy of the color table handle). In 32-bit mode it is important that there
; be exactly one auxWinRec per window. This routine has a bug where -1 color tables can
; cause extra auxWinRecs to be allocated in 32-bit mode.
;
;
; procedure SetWinColor ( theWindow:windowPtr; newColorTable:CTabHandle );
;
; This procedure changes the awCTable field of the theWindow's auxWinRec.
; If newColorTable is equal to the default record's CTabHandle, then
; the auxWinRec is deallocated. If this window does not have an
; auxWinRec, then one is allocated at the head of the list. If theWindow
; is NIL, then the default colors are changed. If a record gets deallocated,
; it's colorTable is disposed unless it has it's resource bit set (then the
; app must take responsibility)
;
; Most of this code is shared with the control manager. Since the auxRec
; offsets are the same for both types of auxrecs, the code should be OK,
; even though the code uses the auxWinRec names.

; <2.2/2.7> Slot Interrupt patch: patches _SIntInstall, and reverses Slot
; interrupt queue order
;
; Change the treatment of Equal Priorities to match the Mac II, which ran the most
; recently installed element soonest when priorities were equal. This code matches
; Inside Mac Vol 5, and treats $FF as highest priority. The Mac II has a bug and
; treats $FF as LOWEST priority within the slot, but as HIGHEST priority across slots.
; Most cards seemed to beleive the documentation, and none have multiple handlers per slot,
; One developer figured out that the Mac II was backwards within the slot, and wanted to
; insert an element ahead of a priority zero (highest with Mac II bug) element. To do
; this, he took advantage of the was that equal priorities were treated on the Mac II,
; which is why we are now patching this to match.

;
; Arguments: D0 (input) : slot number for routine ($0..$E possible)

;
; Function: Installs a slot interrupt poll routine which is called when

; in priority order, $FF highest (first), $00 lowest (last).
;
; When elements with EQUAL priorities exist, the most recently

; <2.7> changes the treatment of Equal priorities to match Mac II.
;
; Only low byte of priority word is used (0-255 range).
; Priorities 200-255 are reserved by Apple.]
;
; The Mac II used to maintain priority across slots, which was
; used when multiple slots interrupted AT THE SAME TIME.
; We no longer support this, and prioritize by slot number instead.
; This will be removed from the Mac II in system 7.0
;
; The Mac II had a bug in SIntInstall, which had $FF as the highest

; DrText had a check to see if the advance width of a character was zero. If so,
