Step 5. Save the BOOT.INI file and restore the “read only” attribute.
4.5 Troubleshooting
Some potential problems and their suggested solutions are:
During installation, no SCSI devices are found.
•
Ensure that the custom setup is chosen on the Setup Method
screen.
•
Ensure that all devices are powered on and terminated correctly.
•
Check that no devices have duplicate SCSI IDs.
•
Make sure INTA is assigned for the PCI slot(s) where your SCSI host
adapter(s) are installed.
•
Ensure that all devices can be seen in the display banner of the
SDMS SCSI BIOS at boot time.
•
For systems with some versions of the Award BIOS, ensure that the
PCI IRQ is set to edge triggered.
System crashes during installation with a message indicating
inaccessible boot device.
•
This error is usually associated with an IRQ, DMA channel, I/O (chip)
address, or BIOS address conflict. Set the SCSI host adapter to use
a different interrupt through the system BIOS in CMOS.
•
A virus sometimes causes this error that infects the Master Boot
Record of the boot device. Use a write-protected DOS bootable flex
containing virus scanning 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.
Older SCSI devices that incorrectly indicate to Windows NT that they
support multiple LUNs usually cause this error.
•
Contact the device manufacturer for a firmware upgrade.
•
Ensure that there are no devices with the same SCSI ID as the host
adapter board.
