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.
