|
|
; Change History (most recent first):
|
|
;
|
|
; <SM2> 5/20/92 stb Change an include to :Internal:Decompression.a. I did this once
|
|
; before, but I donÕt know where it went.
|
|
; <26> 1/19/92 DTY Check if AppleTalk is inactive. If it is, set
|
|
; emAppleTalkInactiveOnBoot to true, to let other things later on
|
|
; in the boot process and the Chooser know that network code
|
|
; shouldnÕt be loaded.
|
|
; <25> 12/18/91 DTY Clear only the decompressPasswordBit in the memory attributes
|
|
; instead of the entire byte.
|
|
; <24> 10/15/91 DTY Set to twoDeepBit to cause one deep calls on the System file to
|
|
; look further down the chain for resources. DonÕt set the
|
|
; overrideNextMapBit (formerly the mapInsertedBit) for the System
|
|
; file.
|
|
; <23> 10/15/91 DTY Set the mapInsertedBit and dontCountOrIndexDuplicatesBit for the
|
|
; System file.
|
|
; <22> 9/18/91 JSM Cleanup header.
|
|
; <21> 7/3/91 JSM Remove obsolete conditionals and obsolete DSAT patch.
|
|
; <20> 6/12/91 LN Removed #includes for private interfaces from public interfaces.
|
|
; Changed #include 'HardwareEqu.a' to 'HardwarePrivateEqu.a'
|
|
; <19> 1/30/91 gbm sab, #38: Change the name of one of the decompressor header
|
|
; files (because Sheila said it was okay)
|
|
; <18> 10/30/90 dba Put code in here to set the bit on the system map so that dcmp
|
|
; resources will be loaded from it.
|
|
; <17> 7/11/90 gbm make changes trending to the elimination of assembler warnings
|
|
; <16> 6/14/90 JSM NEEDED FOR SIXPACK: Changed move.w of emRecSize to move.l. This
|
|
; doesn't really matter unless the ExpandMem block gets above 64K,
|
|
; which will never happen.
|
|
; <15> 5/29/90 DDG NEEDED FOR SIXPACK: Changed all the sixpack conditionals from
|
|
; six-point-oh-seven to six-point-oh-six.
|
|
; <14> 5/24/90 HJR NEEDED FOR SIXPACK: Fixed bug in ExpandMem where the system will
|
|
; create its own when the ROM's is larger.
|
|
; <13> 5/24/90 CCH Made eclipse the highest box flag supported on 6.0.6 and 6.1.
|
|
; (This should not be rolled into SixPac!)
|
|
; <12> 3/22/90 dba get rid of the DSAT 2 code for $700 since new boot code no
|
|
; longer exhibits this problem
|
|
; <11> 3/20/90 DDG Changed Sys607 to work on all machines thru Elsie.
|
|
; <10> 2/28/90 DD put proc and endp around the ADBInitPatch too.
|
|
; <9> 2/28/90 DD added proc and endP directives so we can use the BIND macros in
|
|
; DecompressPatch.a
|
|
; <8> 1/24/90 CV Adding checks to limit the CPUs supported by each system disc.
|
|
; System 6.0.5 will support CPUs through F-19. Sytem 6.0.6 will
|
|
; support CPUs through XO. System 6.1.0 will support CPUs through
|
|
; Erickson.
|
|
; <7> 1/22/90 CCH NEEDED FOR 6.0.5: Now gets the current size from any existing
|
|
; record, and points the expandMem global to the new record before
|
|
; disposing of the old one.
|
|
; <6> 1/19/90 PKE NEEDED FOR 6.0.5 AND Scripts604: install an ADBproc so that
|
|
; ADBReInit will set up the correct KCHR for use by KeyTrans.
|
|
; <5> 1/18/90 DD Changed a comment
|
|
; <4> 1/18/90 DD Moved DeCompressor patch in front of KeyTrans Patch so the
|
|
; conditional cutback will work.
|
|
; <3> 1/17/90 DD Added DeCompressor patch.
|
|
; <2> 1/4/90 PKE Updated conditionals so SS-6.0.4 changes go in 6.0.5 as well as
|
|
; 7.0. Updated header to BBS format.
|
|
; <1> 12/17/89 CCH Adding for the first time into BBS.
|
|
; (BBS versions above, EASE versions below)
|
|
; <1.9> 12/1/89 dba NEEDED FOR 6.0.5: changed conditionals left over from 6.0.4
|
|
; <1.8> 11/16/89 EMT Moved KeyTrans trap as well, since keyboard relies on it.
|
|
; <1.7> 11/16/89 EMT Moved keyboard initialization from ROM75Fix for FullWrite and
|
|
; MacroMaker.
|
|
; <1.6> 8/28/89 SMB NEEDED FOR 604 Scripts: Must increase ExpandMem for TE vectors
|
|
; for Mac Portable for 6.0.4 Script System Builds. Removed load of
|
|
; nEqu.d.
|
|
; <1.5> 8/11/89 dba NEEDED FOR 6.0.4: improved the check for Òtoo newÓ ROMs by
|
|
; checking ROM85 before looking at BoxFlag; left check in for 7.0
|
|
; on the assumption that there will be ROMs too new for us even
|
|
; then
|
|
; <1.4> 8/10/89 CCH NEEDED FOR 6.0.4: For 6.0.4 only, make sure we're running on a
|
|
; pre-F19 system and that we're in 24-bit mode.
|
|
; <1.3> 2/21/89 CCH Added check to see if expandMem has already been initialized
|
|
; before re-initializing it.
|
|
; <1.2> 2/20/89 JB (with DNF) Moved cache control trap (PP332), "not a Mac disk"
|
|
; ExtFSPatch (P003), and MapFBlock (S118,P005) to individual
|
|
; machine patch files. No longer here!
|
|
; <1.1> 1/16/89 CCH Merged 6.0.3 final sources into 7.0.
|
|
; 1/1/89 CCH Start using SysVers equate, and added conditionals for 6.0.4.
|
|
; <1.0> 11/16/88 CCH Added to EASE.
|
|
; (pre-EASE history below)
|
|
; <S518> 7/1/88 EKH Bumped the hex version number to v6.1, for the Altair release.
|
|

|
|
; <PPyyy> 12/3/87 EKH Bumped the hex version number for v4.4 system (used by
|
|
; SysEnvirons calls).
|
|
; <PP296> 10/19/87 SHF Moved call to SCSILoad to each individual patch file (rom75fix,
|
|
; etc.).
|
|
; <PP282> 9/19/87 BB Modified ExtFS patch (S084 in BeforePatches.a) to release the
|
|
; AppleShare FCB following an unsuccessful Close call on an
|

|
|
; <PA254> 8/7/87 bbm bumped version number (SysVersNo) for new release.
|
|

|
|

;######################### ADBReInit PATCH ********########################## <6>
|
|
; ADBReInit causes ADB keyboards to be reset to use KCHR 0. It can be called
|
|
; after booting - for example, on the Portable at wakeup if devices are
|
|
; connected to the external ADB port. This causes problems for international
|
|
; systems, which are normally using other KCHRs. On the non-Roman systems, users
|
|
; may also frequently switch back and forth between various KCHRs. Fortunately,
|
|
; a pointer to the current KCHR is kept in ExpandMem. This patch (actually, an
|
|
; ADBProc) gets the current KCHR pointer from ExpandMem and stuffs it into the
|
|
; keyboard driver data structures for all connected keyboards.
