; Contains: equates for the boot time environment
;
; Copyright: © 1989-1994 by Apple Computer, Inc., all rights reserved.
;
; Change History (most recent first):
;
; <SM8> 2/6/94 IH Added ROM version equates.
; <SM7> 3/11/93 SAM Added sgEDiskStealFLag to boot globs that tells the MMU init
; code whether or not to steal RAM chunks from the map.
; <SM6> 2/20/93 SAM Added emuWarmStartConst - a new warmstart flag for the native
; startup code. Too bad Paula is 5 characters...
; <SM5> 8/19/92 CSS Update from Reality:
; <11> 8/18/92 DTY Change the name of BootGlobs, which is used by the ROM Start
; Manager to StartGlobals to avoid confusion with BootGlobals,
; which is used by the boot code in Boot[1-3].a.
; <SM4> 8/17/92 CCH Added scratch area in boot globs.
; <10> 7/1/92 DTY #1031401: Bump the slop in the system heap up from 44K to 64K.
; This gives a little more room for 'PACK' resource to get loaded
; when the system heap is packed down in low memory conditions.
; <9> 5/28/92 DTY #1030972: Add systemEnabledBit. 'boot' 2 will set this bit if it
; couldnÕt find any Gibblies to boot the machine. 'boot' 3 will
; check this bit and display the ÒThis disk is too old to be used
; on this Macintosh.Ó message.
; <8> 1/23/92 KC Roll in Terror patches from BootEqu.a. Original comments follow.
; {2} 12/20/90 CCH Added defStackAddr equate.
; <7> 1/17/92 DTY Take the kROMVersion equates out of this file; theyÕre defined
; in LinkedPatchMacros.a
; <6> 1/14/92 csd Move the BootGlobals record here from BootCode.a and
; StartSystem.a so we donÕt have to keep the two versions in sync.
; NOTE: BootGlobals is not the same as BootGlobs!
; <5> 12/30/91 RB Added space for Edisk variables in the BootGlobals record.
; <4> 8/21/91 JSM Clean up header.
; <3> 1/30/91 gbm sab, #38: Change the Ôalready including this fileÕ variable to
; all uppercase (for security reasons)
; <1.3> 5/30/89 rwh moved warm start to near top of boot globals record. Added
; bgTopOff, bgPhysicalTableOff.
; <1.2> 5/26/89 rwh renamed BootGlobs fields for consistency. Added HoleSysHeap,
; HoleLowMem.
; <1.1> 5/16/89 rwh added warm start to the boot globals record
; <1.0> 5/13/89 rwh New today
