WD7000 SDLP interface - EXECUTE GENERIC SCSI COMMAND

AH = FFh
SI = 6A6Ah
AL = SCSI Addressing (see #00230)
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.
