|
||
; Change History (most recent first):
|
||
;
|
||
; <SM4> 10/28/92 SWC Changed SlotEqu.a->Slots.a.
|
||
; <SM3> 6/30/92 kc Roll in Horror, comments follow:
|
||
; <H4> 6/10/92 djw Add new selector for doSecondaryInit (a private routine)
|
||
; <H3> 6/10/92 djw Add new private trap macro's for AddCard, RemoveCard,
|
||
; and CheckSlot.
|
||
; <SM2> 5/17/92 kc Add get sGetSRTEntry vector number.
|
||
; <5> 1/7/92 RB Added a couple of records structures used to identify faulty
|
||
; drivers in Apple display cards.
|
||
; <4> 1/30/91 gbm sab, #38: Change the ‘already including this file’ variable to
|
||
; all uppercase (for security reasons)
|
||
; <2> 1/17/90 djw Add new slotmgr private selector GetBoard
|
||
; <1.9> 6/30/89 djw removed pSlotStatus.
|
||
; <1.8> 4/16/89 GGD Added new data structures used by SlotInterrupts.a and
|
||
; VerticalRetraceMgr.a
|
||
; <1.7> 4/12/89 djw Removed including slotequ.a and duplicate state constants
|
||
; (state_sdminit,...)
|
||
; <1.6> 3/28/89 djw added an SRT entries count to globals. Added macros for private
|
||
; routines, added last SRT ptr in globals.
|
||
; <1.5> 3/12/89 djw changed srt link block and added some mark values, deleted
|
||
; SRTlastBlk ptr in globals and substituted expansion chassis
|
||
; support fields.
|
||
; <1.4> 3/1/89 djw change srrblock flag field from byte to long
|
||
; <1.3> 2/20/89 djw added SRT header record definition, added slot mgr globals
|
||
; record. added flag field to srrBlock for enable/disable.
|
||
; <1.2> 1/6/89 djw Add slotVNum for slot version number
|
||
; <1.1> 11/17/88 CCH Added stuff from system build.
|
||
; <1.0> 11/9/88 CCH Adding to EASE.
|
||
; <1.0> 10/24/88 djw Adding for the first time into EASE.
|
||
; 1/10/88 djw created - removed sSDMRecord and state equates
