|||
|
|
- New HalpCreateEisaPCIStructures()
|
|||
|
|
- Del HalpCreateEisaStructures()
|
|||
|
|
- New function HalpEisaPCIDispatch()
|
|||
|
|
- Del function HalpEisaDispatch()
|
|||
|
|
L000 Thu Oct 13 18:09:33 JST 1994 kbnes!kuriyama(A)

|
|
for BBM LED
|
|||
|
|
- Add HalpDisplayLED
|
|||
|
|
- Add HalpLEDDisplayLock
|
|||
|
|
- Add HalpLEDControlBase;
|
|||
|
|
L002 Mon Oct 17 14:21:39 JST 1994 kbnes!kuriyama(A)
|
|||
|
|
change function name EISAPCI... EISA..
|
|||
|
|
H001 Mon Oct 17 14:45:04 JST 1994 kbnes!kishimoto
|
|||
|
|
- Del HalDisplayLED() function definitions.
|
|||
|
|
(We call HalR94aDebugPrint() instead of that.)
|
|||
|
|
H002 Thu Oct 20 20:58:45 JST 1994 kbnes!kishimoto
|
|||
|
|
- add extern ULONG R94aBbmLEDMapped
|
|||
|
|
for debug use only.
|
|||
|
|
H003 Fri Oct 21 15:52:32 JST 1994 kbnes!kishimoto
|
|||
|
|
- add HalR94aDebugPrint() prototype definition.
|
|||
|
|
H004 Mon Jan 16 02:28:58 1995 kbnes!kishimoto
|
|||
|
|
- add HalpPCIConfigLock
|
|||
|
|
S005 Tue Mar 07 14:55:42 JST 1995 kbnes!kuriyama (A)
|
|||
|
|
- add Dma32BitAddresses to AdapterObject
|
|||
|
|
H006 Fri Jul 21 17:40:53 JST 1995 kbnes!kisimoto
|
|||
|
|
- merge ESM functions from J94C
|
|||
|
|
H007 Sat Aug 12 15:12:28 JST 1995 kbnes!kisimoto
|
|||
|
|
- Removed BBMLED, R94ALEDMAP code and _J94C_ definitions.
|
|||
|
|
_J94C_ definition indicates that the status of
|
|||
|
|
the dump switch can acknowledge from Self-test
|
|||
|
|
register.
