Troubleshooting
Server Will Not Boot from a CD-ROM Disk
1. Verify the CD-ROM disk is bootable.
2. Use the BIOS Setup Utility to verify that the CD-ROM Drive is first in the boot order. To
do this:
— Reboot the server and run the (BIOS) Setup Utility (pressing the Delete key).
— Move to the Boot menu.
— If necessary, move the CD-ROM up in the boot order list. This ensures the CD-ROM
will boot before any of the hard disk drives (IDE or SCSI).
— Save and exit the Setup Utility.
If the problem persists, contact the HP Customer Support Center for further troubleshooting
assistance.
SCSI Problems
The SCSI Boot Controller BIOS Has Trouble Loading the Boot Logical Drive
(NOS Drive)
1. Verify the SCSI boot controller is bannering (displaying) on POST.
2. Be sure that the SCSI boot controller’s BIOS is enabled. Check this from the SCSISelect`
Utility. To access this utility, press Ctrl-A when an Adaptec controller banners on POST.
3. Determine what the boot order is for the HP server. To verify that the SCSI boot
controller board is in the correct position in the boot order, press the Delete key on POST
to access the system BIOS Setup Utility. The boot order can be viewed and changed from
this utility. If necessary, change the slot (if applicable) that the SCSI controller is in to
change the location in the boot order.
4. If the problem persists:
a. Clear CMOS and flash the system BIOS. Refer to “Clearing the CMOS
Configuration” in Chapter 3.
b. Repeat step 3.
5. If you installed more than one SCSI controller, try disabling the BIOS on all other SCSI
controller except for the SCSI boot controller. This lets the SCSI BIOS for the boot
controller load and prevents conflicts with other SCSI controllers. If necessary, remove
all the other SCSI controller boards except the SCSI boot controller until the issue is
resolved.
