INT 13 - SyQuest - Generic SCSI pass through
AH = 59h
CX = HOST_ID, 0-based
DX = 80h
ES:BX pointer to SCSI structure (see #00286)
Return: CF clear
AH = 95h
SeeAlso: AH=12h\"SyQuest\",AH=13h\"SyQuest\",AH=1Fh\"SyQuest\"

Format of SyQuest SCSI structure:
Offset Size Description (Table 00286)
 00h WORD opcode (see #00287)
 02h BYTE target\'s SCSI 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 DWORD request data length
 0Ch DWORD result data length (actual length of data transferred)
 10h DWORD -> CDB (see #03236,#03237,#03238)
 14h DWORD -> data buffer
Note: The handler does not perform a \'Request Sense\' command if there was an
 error

(Table 00287)
Values for SCSI 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 command
 04h device reset
 05h SCSI bus reset
