Int 78 Fn 00  - Targa.dev - Cmc International Scsi Device Driver - Set I/  [d]

   AH = 00h
   DX = interface board I/O port

Return: CF set on error
       AL = error code (see below)

Note:  if this routine is not called, the port is the driver's default
     (usually 0280h or 0300h)
   an installation check is performed by TARGA.DEV upon initialization
     by checking for the string "SCSI" at offset 03h into the interrupt
     handler

Values for error code:
 00h   illegal command given to SCSI code
 01h   invalid I/O port specified (must be from 100H to 3F8H, and must be on
     an 8-port boundary)
 02h   invalid DMA channel specified (must be from 1 to 3)
 03h   invalid SCSI board number specified (must be from 0 to 7)
 04h   error from data register test during self-test
 05h   SCSI input signals not all 0 when SCSI RST activated
 06h   SCSI input signals not all 0 before selecting a SCSI device
 07h   BSY signal is active; SCSI bus is busy
 08h   SCSI board not selected, BSY signal did not come on in response to
     raising SEL
 09h   time-out waiting for status state, signifying end of DMA transfer
