|
|
; <SM7> 11/9/93 SAM Roll in <MC5> from mc900ftjesus.
|
|
; <MC4> 11/9/93 SAM Reducing the max edisk size to 255 MB. Tough.
|
|
; <SM6> 11/8/93 SAM Roll in <MC3> from mc900ftjesus.
|
|
; <MC3> 11/8/93 SAM Added MaxRamDiskSize. Currently set to 256MB -1.
|
|
; <SM5> 10/28/93 CCH Just checking to see if you were paying attention.. Really added
|
|
; EDiskProtect equate to EDiskDriveInfo record.
|
|
; <SM4> 10/28/93 CCH Added EDiskProtect equate to EDiskDriveInfo record.
|
|
; <SM3> 6/17/93 kc Roll in Ludwig.
|
|
; <LW5> 6/16/93 KW Ok mess with MinHeapSize again. now equal to 0x00260000, which
|
|
; is the current value of the mnrm resource in the memory control
|
|
; panel. Power users will be able to open the memory control
|
|
; panel and lower the mnrm resource to this value and still have a
|
|
; ram disk.
|
|
; <SM1> 11/01/92 HY Added GintyHeader record to support ROM disks.
|
|
; <5> 10/28/91 SAM/KSM Rolled in Regatta file.
|
|
;
|
|
; Terror Change History:
|
|
;
|
|
; <7> 6/26/91 CCH Moved RAM disk base to slot 7 space so as not to conflict with
|
|
; DB Lite's frame buffer,.
|
|
; <6> 6/25/91 CCH Moved RAM disk base to $60000000 and added MinRamDiskSize
|
|
; equate.
|
|
; <5> 6/13/91 CCH Moved RamDiskSize to EDiskDriveInfo record.
|
|
; <4> 6/13/91 CCH Moved bRamDisk equate in from MMUTables.a.
|
|
; <3> 4/2/91 CCH Reduced minimum heap size to allow for space used by BootGlobs.
|
|
; <2> 12/20/90 CCH Added memory allocation equates for Edisk driver.

|
|
; <2> 5/16/90 JJ Modify parameter ram byte address. Merged two bytes ($75-76)
|
|
; into one ($AF) since only 1 bit was used from $75.
|
|
; <1.2> 5/26/89 GMR Changed RomSpaceEnd from $F00000 to $E00000, added new RAM disk
|
|
; size status code (drvSizeCode)
|
|
; <1.1> 2/21/89 GGD Added support for SLIM interface adapter. Changed origin in
