Troubleshooting
DURING INSTALLATION, NO SCSI DEVICES ARE FOUND
a. Insure that the custom setup is chosen on the Setup Method screen.
b. Insure that all devices are powered on and terminated correctly.
c. Check that no devices have duplicate SCSI IDs.
d. Make sure INT A is assigned for the PCI slot(s) where your SCSI host adapter(s)
are installed.
SYSTEM CRASHES DURING INSTALLATION WITH A MESSAGE INDI-
CATING INACCESSIBLE BOOT DEVICE
a. This error is usually associated with an IRQ, DMA channel, I/O (chip) ad-
dress, or BIOS address conflict. Set the SCSI host bus adapter board to use a
different interrupt.
b. This error is sometimes caused by a virus infecting the Master Boot Record of
the boot device. Use a write-protected DOS bootable flex containing virus
scannning and cleaning software to check for any viruses on the boot device,
and remove if any are found.
A DISK DRIVE IS RECOGNIZED AS SEVEN DIFFERENT DEVICES WHEN
ONLY ONE IS PHYSICALLY CONNECTED TO THE SCSI BUS.
a. This error is usually caused by older SCSI devices incorrectly indicating to NT
that they support multiple LUNs. Contact the device manufacturer for a firm-
ware upgrade.
PROBLEMS WITH ULTRA SCSI (FAST 20) DEVICES USING ULTRA SCSI
PROTOCOL
a. If the system is configured with a Symbios Logic host adapter that supports
Ultra SCSI, an Ultra SCSI device is on the SCSI bus, and Ultra SCSI support
by the SYMC8XX.SYS driver is enabled, intermittent problems and possible
system crashes can occur if the SCSI bus cable and terminators do not con-
form to the Ultra SCSI specification.
b. If the system is bootable, disable Ultra SCSI support using the procedure de-
scribed above or below.
c. If the system is not bootable, use the Emergency Repair Disk to restore the
system to a previously working configuration (with Ultra SCSI disabled).
d. If the system operates properly without Ultra SCSI enabled, it is highly likely
that the SCSI bus cable and terminators are not configured correctly for Ultra
SCSI. See the Symbios Logic host adapter User’s Guide for information on
Ultra SCSI cabling requirements.
