Format of NetWare "Get Drive Mapping Table" reply packet:
Offset	Size	Description	(Table 02230)
 00h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	(big-endian) clock tick elapsed since system started
 04h	BYTE	fault tolerance (SFTsee System File Table) level
 05h	BYTE	number of logical drives attached to server
 06h	BYTE	number of physical drives attached to server
 07h  5 BYTEs	disk channel types (00h none, 01h XTIBM PC XT, 02h ATIBM PC AT, 03h 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.,
		  04h disk coprocessor drive, 32h-FFh value-added drive types)
 0Ch	WORD	(big-endian) number of outstanding controller commands
 0Eh 32 BYTEs	drive mapping table (FFh = no such drive)
 2Eh 32 BYTEs	drive mirror table (secondary physical drive, FFh = none)
 4Eh 32 BYTEs	dead mirror table (last drive mapped to, FFh if never mirrored)
 6Eh	BYTE	physical drive being remirrored (FFh = none)
 6Fh	BYTE	reserved
 70h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	(big-endian) remirrored block
 74h 60 BYTEs	SFTsee System File Table error table (internal error counters)
