; Contains: patches for the first ROMs shipped in a Macintosh Portable ($037A)
|

|
|
;
|
|
; Change History (most recent first):
|
|
;
|
|
; <66> 1/19/92 DTY Look at emAppleTalkInactiveOnBoot before getting the AppleTalk
|
|
; version. If AppleTalk is inactive, donÕt set up the serial port
|
|
; for use by AppleTalk. This is part of a large conspiracy to
|
|
; convince the universe that AppleTalk really isnÕt around if it
|
|
; is inactive.
|
|
; <65> 12/26/91 RB Rename definition of SleepQRec in the serial patch because it is
|
|
; also used for Power Mgr.
|
|
; <64> 12/2/91 SAM Using official boxflag equates now.
|
|
; <63> 10/28/91 SAM/KSM Rolled in Regatta file:
|
|
; Added Asahi Sony icons.
|
|
; To distinguish between the Portable and Asahi (It's a Sony!)
|
|
; that have the same ROM number & boxFlag, if the ROM minor
|
|
; version is 1.1f1 then boxAsahi is jammed into BoxFlag. This is
|
|
; placed before Gestalt gets loaded and uses boxFlag.
|
|
; <62> 8/30/91 DTY Define onHcMac in this file because itÕs not an available
|
|
; feature in BBSStartup any more.
|
|
; <60> 6/12/91 LN added #include 'InternalOnlyEqu.a'
|
|
; <59> 6/12/91 LN removed #include 'HardwareEqu.a'
|
|
; <58> 3/18/91 gbm SAM, #gbm-0009: Take out code that saves and restores logical
|
|
; memory size and physical memory size around the installation of
|
|
; the RAM-based Gestalt (the portable ROM does it wrong, and we
|
|
; don't want its values)
|
|
; <57> 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.
|
|
; <56> 3/15/91 DTY kip, #fixGestalt: Add Gestalt fixes ('ptch' 5) to Portable
|
|
; because some of GestaltÕs globals are trashed.
|
|
; <55> 3/4/91 dba dty: get rid of SysVers conditionals
|
|
; <54> 2/26/91 eh (djw) Fixed bug that was causing crash on serial read if a break
|
|
; is received. An address offset was off by 2.
|
|
; <53> 2/21/91 eh (djw) Fixed bug in the serial driver that was preventing use of
|
|
; one port when Nike was printing on the other.
|
|
; <52> 1/19/91 mbs (jg) Include ATalkPrivateEQU.a to get AGBHandle equates since
|
|
; they were moved out of ATalkEQU.a.
|
|
; <51> 1/19/91 eh (djw) Patch Port A async serial driver headers to insert
|
|
; signature longword used by serial driver linked patch. Insert
|
|
; signature before already patched Port B headers. Changed port b
|
|
; arbitration code to call the new 'atkv' Gestall call instead of
|
|
; the old 'atlk'.
|
|
; <50> 1/14/91 eh (djw) Added external clocking support for Nike Printer to the
|
|
; Async Serial Driver.
|
|
; <49> 12/15/90 djw Add SCSI Mgr support for Quantum 7.9 ROM problem by adding a
|
|
; separate TIB interpreter and replacing blind write
|
|
; <48> 12/14/90 dnf (jsm) Nuke the dummy patch on ExtFSHook.
|
|
; <47> 12/14/90 DFH <bbm> Removed MoveHHi and StackSpace patches. They were to
|
|
; workaround a SuperCard 1.0 bug, but SuperCard 1.5 has been
|
|
; available for some time. SuperCard 1.0 initialization code
|
|
; lowered ApplLimit directly instead of calling SetApplLimit. This
|
|
; left HiHeapMark up high, so StackSpace returned less than the
|
|
; true amount, and SuperCard put up an alert because it thinks the
|
|
; stack is getting full. SuperCard 1.5 calls SetApplLimit, so
|
|
; HiHeapMark is OK.
|
|
; <46> 11/14/90 JSM <bbm> Move come-from patch on _TEAutoView to fix dialog manager
|
|
; bug to DialogManagerPatches.a.
|
|
; <45> 9/25/90 KIP Change Sound Mgr. to a linked patch.
|
|
; <44> 9/21/90 VL Moved PowerMgr patches to PowerMgrPatches.a so that SystemTask
|
|
; will not be patched before the Notification Manager gets to
|
|
; patch it.
|
|
; <43> 9/20/90 KST Install a dummy patch for ExtFSPatch so that it will work for a
|
|
; linkpatch.
|
|
; <42> 8/18/90 dba get rid of ptchInst 7 and 8 (Sony Format and Eject patches) as
|
|
; they are now linked patches
|
|
; <41> 8/14/90 DTY Removed TextEdit patches since theyÕre in a linked patch now.
|
|
; (For real this time.)
|
|
; <40> 8/14/90 JWK NEEDED FOR SIXPACK: Removed old Slot Mgr Gestalt selectors.
|
|
; <39> 8/13/90 JWK NEEDED FOR SIXPACK: Added NuBus and Serial Gestalt selectors.
|
|
; <38> 8/8/90 SAM Changing DispatchHelper & ProcHelper into an old style ptch.
|
|
; ¥¥¥--> Temporary <--¥¥¥ Remove when the Sound ptch get converted
|
|
; into an Lptch.
|
|
; <37> 7/30/90 dnf Remove installation of ptch 18 (File Manager) and ptch 6 (Btree
|
|
; Manager), now linked patches
|
|
; <36> 7/23/90 dba get rid of ptch 25 for 7.0; it is covered by DialogMgrPatches;
|
|
; get rid of extraneous pre-6.0.6 SysVers conditionals; removed
|
|
; ptchInst 16 since PrGlue is a linked patch
|
|
; <35> 7/20/90 DTY Removed ptchInst 10 & 11 (Bass patches) since Bass is (finally)
|
|
; a linked patch.
|
|
; <34> 7/19/90 CCH NEEDED FOR SIXPACK: Removed HwPriv patch, its now a
|
|
; linked-patch.
|
|
; <33> 7/19/90 GMR Install ptch 7 to change eject track from 79 to 40.
|
|
; <32> 7/16/90 gbm Warning cleanup
|
|
; <31> 7/2/90 DTY Removed ptchInst 21 since Resource Manager extensions are now a
|
|
; linked patch.
|
|
; <30> 6/25/90 DTY Removed ptchInst 9 since ScrollSpeedFix is now a linked patch.
|
|
; <29> 6/19/90 VL Remove PtchInst 29 since MiscPatches is a linked patch
|
|
; now.
|
|
; <28> 6/12/90 JSM Remove PtchInst 33 since PPC Toolbox is a linked patch now.
|
|
; <27> 6/7/90 EMT Remove PtchInst 17 since Layer Manager is a linked patch now.
|
|
; <26> 6/7/90 VL Remove ptchinst 28 since HelpMgr is a linked patch now.
|
|
; <25> 5/29/90 DDG NEEDED FOR SIXPACK: Changed all the sixpack conditionals from
|
|
; six-point-oh-seven to six-point-oh-six.
|
|
; <24> 5/10/90 JSM AliasMgr now a linked patch, don't install it here anymore.
|
|
; <23> 5/4/90 HJR Reset the projector date on this file.
|
|
; <22> 5/3/90 MSH Fixed the modem and can't read 800k disks bug.
|
|
; <21> 5/1/90 CCH Added some Gestalt patches (nMgr, Misc, removed VIA,SCC,RBV).
|
|
; <20> 4/21/90 csd added patch install of ptch 16 (PrGlue).
|
|
; <19> 4/16/90 DDG Rolled over changes from the split off sources including a
|
|
; hwpriv patch and installing patch 25 (generic system patch). I
|
|
; also changed the spline fonts equate to use the build variable
|
|
; hasSplineFonts.
|
|
; <18> 4/4/90 KON Removed ptchinst 36 and 44 since they are now linked patches.
|
|
; <17> 3/29/90 KON Add ptch 40, quickdraw stuff for all B&W machines.
|
|
; <16> 3/27/90 PKE Deleted import (currently conditionalized out) of NewSwapIcon,
|
|
; which no longer exists in this PTCH.
|
|
; <15> 3/26/90 PKE Moved definition of symbols that control Script Mgr patch and
|
|
; 'ptch' installation into ScriptPriv.a. Renamed symbols and added
|
|
; some.
|
|
; <14> 3/23/90 NC Added ptch 43 for System 6.0.6 on up. This is for Sound.
|
|
; <13> 3/4/90 PKE Changed _UprText to _UpperText to match new Traps.a.
|
|
; <12> 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).
|
|
; <11> 2/22/90 PKE Replaced obsolete _LwrStringToUpr opword with _UprText. Removed
|
|
; setting of temporary sVectFixSpExtra vector (see <4>); we no
|
|
; longer need it.
|
|
; <10> 1/31/90 SMB NEEDED FOR Scripts604 and 6.0.5 - Fixed Dialog Mgr bug that
|
|
; didn't get rolled into rom. Have to do a come-from patch in
|
|
; TEAutoView to fix a rect for R-to-L text.
|
|
; <9> 1/29/90 MSH Misplaced label. All better now.
|
|
; <8> 1/29/90 MSH PowerOff fix is changed to remove the power control call to the
|
|
; PMGR. The call prevented the AppleTalk driver from resetting
|
|
; the SCC before closing. Added a wake up procedure for the sleep
|
|
; queue to reset the SCC whenever waking and no one is using the
|
|
; driver. GMR added a patch to the EDisk driver to return
|
|
; IOActCount correctly.
|
|
; <7> 1/18/90 MSH Roll in latest version of Pmgr trap from main sources. Fixed the
|
|
; trap to preserve the VIA sound enable bit. Added intercept to
|
|
; PowerOff trap to reset the SCC before calling the ROM version.
|
|
; <6> 1/12/90 CCH Added include of ÒHardwarePrivateEqu.aÓ.
|
|
; <5> 1/11/90 PKE Changed quotes in previous comment to ÒÓ so scripts don't get
|
|
; messed up.
|
|
; <4> 1/11/90 PKE Initialize Script Manager's new sVectFixSpExtra vector. Changed
|
|
; so PtchInst 0 is conditionalized on ÒScripts604 OR (SysVers >=
|
|
; $605)Ó instead of ÒScripts604 OR (SysVers >= $700)Ó; at the
|
|
; moment, this won't affect anything since Scripts604 is presently
|
|
; TRUE for the 6.0.5 build.
|
|
; <3> 1/4/90 BBM NEEDED FOR 6.0.5. We now patch out the soundmanger on all
|
|
; cpuÕs.
|
|
; <2> 1/4/90 dba converted header; used PatchMacros setTrap and stuffOldTrap
|
|
; instead of Set/GetTrapAddress (makes the object code a little
|
|
; bit shorter)
|
|
; <1> 12/17/89 CCH Adding for the first time into BBS.
|
|
; <6.1> 12/13/89 MSH NEEDED FOR 6.0.5:Two more fixes. 1) Added fix to PMGR ADB send
|
|
; command. Commands
|
|
; <6.0> 12/11/89 GMR Added ptchInst 8; Sony Format patch is now in it's own patch
|
|
; file (FormatPatch.a).
|
|
; <5.9> 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.
|
|
; <5.8> 12/4/89 MSH NEEDED FOR 6.0.5: Completely new patch for the PmgrOpPatch to
|
|
; fix two problems. 1) Moved the delay in SerialPower to fix poor
|
|
; hardware design, i.e. let the -5v generator to stabilize before
|
|
; turning on the other power planes. 2) Added modem port polling
|
|
; to PmgrOp to support high speed (57.6kb) serial.
|
|
; <5.7> 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.
|
|
; <5.6> 11/21/89 EMT NEEDED FOR 6.0.5: Added humane scrolling.
|
|
; <5.5> 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.
|
|
; <5.4> 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. Also (applies to 7.0 only) - fixed
|
|
; install for 4.7 to use lea instead of leaROM.
|
|
; <5.3> 10/15/89 BAL Added support for 32-Bit QuickDraw pictures via ptch 36
|
|
; <5.2> 10/6/89 JSM Removed SnarfMan 'ptch', now PACK 13.
|
|
; <5.1> 9/26/89 CVC Added PPC Toolobox as a 'ptch'.
|
|
; <5.0> 9/25/89 EMT Added ptchs 18, 6, 29.
|
|
; <4.9> 9/19/89 RLC Added Balloon Help (ptch 28) to file.
|
|
; <4.8> 9/18/89 BBM Install resource manager extensions, ptch 21
|
|
; <4.7> 9/18/89 PKE For 7.0, patch Script Manager internal routine SwapIcon to use
|
|
; new 'kscn' resource type instead of 'SICN'.
|
|
; <4.6> 9/17/89 PKE Decided to patch out GetScript/SetScript entirely in ptch 27, so
|
|
; we no longer patch them here (see 4.5). Also, for 7.0 we now
|
|
; install the Script Manager's Gestalt function in ptch 27 instead
|
|
; of here (see 2.7).
|
|
; <4.5> 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.
|
|
; <4.4> 9/4/89 PKE Install Script Manager 7.0 extensions, ptch 27. Set Script Mgr
|
|
; version for 7.0.
|
|
; <4.3> 8/28/89 PKE For 7.0, initialize additional Script Mgr vectors for
|
|
; SMgrCalcRect and SMgrInitFonts.
|
|
; <4.2> 8/27/89 PKE NEEDED FOR Scripts604, 6.0.5: Bump Script Manager version for
|
|
; Scripts604 or SysVers > $604, since IntlForce bug fix (3.8) is
|
|
; installed.
|
|
; <4.1> 8/25/89 SMB NEEDED FOR Scripts604: install TextEdit (ptch0) for 6.0.4 Script
|
|
; System builds.
|
|
; <4.0> 8/21/89 PKE NEEDED FOR 6.0.4: Conditionalize 3.8 for Scripts604 OR (SysVers
|
|
; > $604)
|
|
; <3.9> 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.
|
|
; <3.8> 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).
|
|
; <3.7> 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?).
|
|
; <3.6> 8/20/89 PKE NEEDED FOR 6.0.4: Added (from PatchIIciROM.a) MkTbl macro and
|
|
; code to fix up patch addresses. This is needed to make
|
|
; JmpROM/JsrROM/CmpRA work, and fixes a problem in the
|
|
; InitProcMenu patch (3.4).
|
|
; <3.5> 8/19/89 MSH Commented out GGD's Sane Optimization, it breaks Excel 2.2.
|
|
; <3.4> 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)
|
|
; <3.3> 8/15/89 prp Added Alias Manager and Folder Manager support.
|
|
; <3.2> 8/11/89 MSH Expanded the Sleep trap patch to fix the passing of the sleepnow
|
|
; code to the sleep queue entries, sleepnow should be converted to
|
|
; sleepdemand before calling them.
|
|
; <3.1> 8/10/89 CCH NEEDED FOR 6.0.4: Added gestalt location error patch and
|
|
; installation.
|
|
; <3.0> 8/9/89 CCH NEEDED FOR 6.0.4: Added patch to gestaltQuickdrawVersion to
|
|
; return two digit versions. Added patch to make
|
|
; gestaltLowMemorySize and gestaltParityAttr exist on Portable.
|
|
; <2.9> 8/8/89 dba NEEDED FOR 6.0.4: added InitProcMenu patch
|
|
; <2.8> 8/7/89 PKE NEEDED FOR 6.0.4: In gestaltScriptMgr function, if gestalt
|
|
; selector is undefined, just leave gestalt result alone.
|
|
; <2.7> 8/5/89 PKE NEEDED FOR 6.0.4: Add Gestalt function for Script Manager,
|
|
; install corresponding Gestalt selectors.
|
|
; <2.6> 7/26/89 GGD NEEDED FOR 6.0.4 Added SANE optimization to bypass the package
|
|
; manager and dispatch directly to the SANE package in ROM.
|
|
; <2.5> 7/24/89 PKE NEEDED FOR 6.0.4: Remove Script Manager patches, since these
|
|
; were fixed in Esprit ROM after all.
|
|
; <2.4> 7/19/89 JSM Install SnarfMan 'ptch'.
|
|
; <2.3> 7/10/89 PKE NEEDED FOR 6.0.4: Put in Script Manager ROM patch code, but
|
|
; don't install patches yet (we need to wait for final ROM and
|
|
; adjust addresses accordingly). We patch InitResources,
|
|
; UprString, GetFormatOrder to match changes in Aurora ROM that
|
|
; were too late for Esprit.
|
|
; <2.2> 7/3/89 NJC Sound Manager Extensions (ptch 23) rolled in for real.
|
|
; <2.1> 6/19/89 MSH Low power resource ID numbers changed.
|
|
; <2.0> 5/31/89 CEL Only defined Spline_Font variable if it is undefined - makes it
|
|
; easier to build test 6.0.4 systems
|
|
; <1.9> 5/25/89 EMT Correctly detach all SICN and STR resources.
|
|
; <1.8> 5/25/89 EMT Added Window Manager extensions for Esprit.
|
|
; <1.7> 5/24/89 MSH Detach all SICN and STR resources.
|
|
; <1.6> 5/3/89 CEL Rolling in Bass for the first time into EASEÉ
|
|
; <1.5> 3/30/89 MSH Load both the system disk version and the rom version.
|
|
; <1.4> 3/30/89 MSH Added a load of the watch cursor from rom and saved the pointer
|
|
; in pmgr locals.
|
|
; <1.3> 3/30/89 MSH Removed the unmount patch completely, in rom now.
|
|
; <1.2> 3/22/89 MSH Cache control trap moved to ROM and Unmount patch made
|
|
; universal. Unmount install searches ROM for required entry
|
|
; points and pokes them into vectors for unmount patch to use.
|
|
; <1.1> 3/15/89 MSH Real patches added today. Unmount patch for AppleShare ("ptch
|
|
; 8"), is loaded if there. Cache trap is here now but will be
|
|
; rolled into ROM for next release.
|
|
; <1.0> 3/6/89 CCH Adding to EASE for first time.

; Async Serial Driver Patch
|
|
;
|
|
; Traps patched: -- The AsyncVector, which is in the middle of the OS ToolTable
|
|
; is patched, Trap number = $A0BE
|
|
;
|
|
; HISTORY:
|
|
; <50> New patch:
|
|
; added nike printer support:
|
|
; -- patched control call 16 in bypass driver to use bit 6 for setting
|
|
; external/internal clocking modes.
|
|
; -- Patched both bypass and IOP code to add status call to return version.
|
|
; -- Patched InitSCC routine in bypass driver to use this RAM-based table so
|
|
; that clocking mode is now variable instead of hard-wired to internal only.
|
|
; -- Patched bypass mode driver to set bit 3 of AsyncErr if break rcvd.
|
|
; added BAP support:
|
|
; -- patched out .Bin and .Bout driver headers to get driver storage pointer
|
|
; from expanded mem.
|
|
; -- patched out B port interrupt handlers to get driver storage pointer
|
|
; from expanded mem and to get DCE pointer from Unit Table.
|
|
;
|
|
; <51> We patch all the port A driver headers (port B driver headers already patched)
|
|
; so that we can put a signature word before each header that we can use
|
|
; to identify ourselves as the Apple async serial driver. We do this
|
|
; right now so that that our linked patch on Open (in Serialpatches.a) will
|
|
; not stomp the version number of some third party driver that sticks them-
|
|
; selves into our spot in the unit table. I think this idea will come in
|
|
; handy later as well.
|
|
; I think i'll use the signature word 'wong'.
|
|
; Also, fix the port arbitration code in Open and Close to make call to the
|
|
; new 'atkv' Gestalt call instead of the old 'atlk' call. We do this because
|
|
; the new call return atalk version number regardless of whether MPP driver
|
|
; is open (i.e. appletalk is active).
|
|
;
|
|
; <53> Fixed bug in external clock stuff that was causing us to disable
|
|
; internal clocking on both ports if we were trying to do external
|
|
; clocking on just one. So Nike would print but Tabasco would just
|
|
; sit there. The fix was to set clocking params at each time we go
|
|
; thru InitSCC, rather than just once during the external clocking
|
|
; control call. This way even tho the ports share the InitSCCTable,
|
|
; we set the Table properly by keying off of the value in CtlOptions
|
|
; variable, which they don't share.
|
|
; <54> Fix address offset for the readrqdone routine. we were off by 2.
|
|
; We were crashing if read pending and break rcv'd.
|
|
; <57> Status calls 9 and $8000 return static version number instead
|
|
; of what's in the DCE.

|
; Beginning code for Quantum 7.9 ROM fix
|
|
;
|
|
; Detailed description of the Quantum problem and solution:
|
|
;
|
|
; Quantum drives with the firmware version 7.9, has a problem with loosing the last byte
|
|
; of a block during a multi-block write. The problem occurs when the time between blocks
|
|
; written to the SCSI bus on the CPU side, is greater than 482 microseconds. This may
|
|
; occur in situations where there are a lot of interrupts. When conditions are right and
|
|
; the problem happens, the last byte of the previous block (in a multi-block transaction),
|
|
; is "eaten" by the drive. Any checksum or CRC calculated by the drive is correct,
|
|
; because the drive calculates it after the byte has been corrupted. This problem is
|
|
; especially frequent when email packages are installed on the Mac, since they generate
|
|
; a lot of interrupts which take a long time. This problem only occurs during fast
|
|
; writes in the SCSI manager (pseudo-dma mode).
|
|
;
|
|
; The way the SCSI manager currently works is it gets a TIB packet which contains the
|
|
; instructions on how to talk to a particular device. Included in the TIB is when to
|
|
; re-synchronize with the drive by waiting for a *REQ. When we see *REQ, the SCSI
|
|
; manager then begins the next TIB data transfer instruction and loads a byte of data
|
|
; into the 53C80's output register. After the first byte is "manually" sent, the
|
|
; hardware handshaking automatically takes care of the *REQ and *ACK handshaking. When
|
|
; the TIB write transfer is complete, pseudo-dma is disable, which releases *ACK,
|
|
; completing the handshake. This allows the target to assert *REQ when it is ready.
|
|
;
|
|
; The window of vulnerability is between the last byte of the previous block and the
|
|
; first byte of the next block. More correctly, it is between the rising edge of *ACK
|
|
; and the falling edge of the next *ACK. Because we release *ACK to synchronize, an
|
|
; interrupt may come in and delay the next transfer.
|
|
;
|
|
; The solution to the problem is to pre-load a data byte into the 53C80's data output
|
|
; register before we release *ACK. There are two ways of releasing *ACK: disable pseudo
|
|
; dma, and write a byte to the data output register. Leaving pseudo-dma enabled through
|
|
; the entire TIB will mean that whenever a *REQ occurs, there will be data available in
|
|
; the output register. This means there will be no delay between bytes because the
|
|
; hardware is not subject to interrupt delays.
|
|
;
|
|
; This patch therefore involves patching the TIB interpreter and the fast write routine
|
|
; in the SCSI manager. There are five versions of the SCSI manager to patch: Mac Plus,
|
|
; SE, Mac II, Portable, and IIci.
