Format of SyQuest SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer.	A host adapter connects the SCSI bus to the computer's own bus.  See also ESDI, IDE. structure:
Offset	Size	Description	(Table 00286)
 00h	WORD	opcode (see #00287)
 02h	BYTE	target's SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer.	A host adapter connects the SCSI bus to the computer's own bus.  See also ESDI, IDE. ID
 03h	BYTE	target's logical unit number
 04h	BYTE	data direction (00h no data xfer, 01h data in, FFh data out)
 05h	BYTE	host status
		00h successful
		01h selection time out
		02h data over-run or under-run
 06h	BYTE	target status at command completion
		00h successful
		02h check status
		08h busy
 07h	BYTE	command data block length
 08h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	request data length
 0Ch	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	result data length (actual length of data transferred)
 10h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	-> CDB (see #03236,#03237,#03238)
 14h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	-> data buffer

Values for SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer.	A host adapter connects the SCSI bus to the computer's own bus.  See also ESDI, IDE. opcode:
 00h	verify interface
	clears carry flag and returns if function is available
 01h	returns the ID of the INT 13h Handler in a NULL terminated string of
	length less than 40 byte including the terminator.
	The string is stored in the buffer pointed by p_buf.
 02h	device mapping info. The caller provides a one byte buffer.
	The handler stores the Int 13h Device ID (80h or above) in the buffer.
	It stores 0 if that target does not exists.
 03h	execute SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer.	A host adapter connects the SCSI bus to the computer's own bus.  See also ESDI, IDE. command
 04h	device reset
 05h	SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer.	A host adapter connects the SCSI bus to the computer's own bus.  See also ESDI, IDE. bus reset
