Q&A-4

FlashPoint™ LT BT-930 User’s Manual

Q. Why does my system lock up on bootup after
connecting to an external SCSI device?

A. Double check for proper SCSI bus termination and check connections and
cabling.

Q. I added a new SCSI device to one of the Model C
SCSI host adapters. Either it is not seen or the system
hangs when the host adapter BIOS tries to scan it. Do
I have the proper SCSI bus termination?

A. This problem occurs mainly because the new device is not SCSI II FAST.
You need to change the Enable Fast Transfer option to No in the AutoSCSI
Configuration Menu. Disable the Enable Synchronous Negotiation option
too, if it is not supported by the device.
