Int 11 Fn FF - Wd7000 Sdlp Interface - Execute Generic Scsi Command [d]
AH = FFh
SI = 6A6Ah
AL = SCSI Addressing
bits 2-0 SCSI Target LUN (logical unit number)
bits 5-3 SCSI Target ID
bit 7 write flag, set for write operations, clear otherwise
CX = bytes of data to be transmitted (max FFF0h)
DH = 00h
DL = length of SCSI Command Descriptor Block
DS:DI -> SCSI Command Descriptor Block
ES:BX -> data buffer
Return: CF set on error
AL = error code
CF clear if successful
Note: because of busmaster operations with WD7000FASST avoid accessing
video memory directly; check 386 memory manager for VDS support.
The WD7000XTAT works with programmed IO and does not have this
limitation.
