sorry - forgot about TI Sync jumper - you want that disabled
for workstations...I think servers are ok with having enabled (no jumper).

"Target Initiated Synchronous Negotiations" is when the Target device
(eg drive) realizes it doesn't have an agreement with the Initiator
(eg host controller) about how fast to send "synchronous" data (SDTR).
Even though the SCSI protocol allows this, older products didn't
do this and the PDC didn't need to (and can't) handle it.
