|
; <SM20> 1/25/94 DCB Added space in the C0C globals for our own private deferred task
|
|||
|
|
; queue.

|
|
; stack switching mechanism. Adding support for Cold Fusion.
|
|||
|
|
; Rearranging HW/SW Init code. Some code optimizations. Changed
|
|||
|
|
; Record_Event trigger to use a couple of values in SCSIGlobals.
|
|||
|
|
; <SM8> 5/29/93 PW Adding comment about globals stolen.
|
|||
|
|
; <SM7> 5/25/93 DCB Update from Ludwig (the three items below this one)

|||
|
|
; <LW7> 5/21/93 mal Changing GetXPTg to use simple indirection instead of [] stuff.
|
|||
|
|
; <LW6> 5/20/93 DCB Adding two fields to the XPT globals to support turning off
|
|||
|
|
; deferred completion routines from inside debuggers.
|
|||
|
|
; <LW5> 5/20/93 PW Added SCSIGlobalsRec from SCSIPriv and into these, I added jump
|

|
|
; <SM6> 5/5/93 PW Converted names to meanies-friendly names. Updated with latest
|
|||
|
|
; from Ludwig stuff.
|

|
; <SM5> 4/8/93 DCB Added a copy of the C0C SCSI Globals which have been modified
|
|||
|
|
; for use by the new SCSI Manager.
|
|||
|
|
; <SM4> 1/31/93 PW Update from the latest of Ludwig. Also changes required for PDM
|
|||
|
|
; (will update Ludwig with these as needed myself).

|||
|
|
; <LW3> 1/27/93 PW Changed bogus to syncUnsafeCount.
|
|||
|
|
; <LW2> 12/18/92 PW Added syncReqEnabled counter (bogus field right now).
