TOSHIBA XM-6401B/TXM6401F1 CD-ROM Drive 5
All SCSI devices attached to your computer are assigned a SCSI-ID
number from 0 to 7. Your CD-ROM’s SCSI ID must be set so that its
ID number does not conflict with any other device’s SCSI-ID in your
system. In most cases your CD-ROM will come set to SCSI ID 0. If
your CD-ROM is the only SCSI device connected to your computer,
you should leave the jumpers as they are. If you have additional SCSI
devices (another CD-ROM, hard drive, etc.) you will be “daisy-chain-
ing” these devices. Each SCSI device must have a different SCSI ID.
Note that your SCSI interface card in most cases has a SCSI ID of 7.
The chart below shows the jumper settings for the eight possible ID
numbers:

Parity Jumper
The Parity Jumper should be set to OFF (no jumper present). This
jumper activates/de-activates the parity bit check function on the SCSI
data bus. This enhances data bus reliability. (Cannot be used if no
parity generation function is provided on the I/F card.)
