INT 11 - 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. SeeAlso: INT 21/AX=4402h"ASPI",INT 2F/AX=7F01h
