C. Ensure that SCSI signals are properly terminated. Only the last physical SCSI device on the bus
should be terminated. (Refer to Chapter 3 for more information on connecting SCSI devices.)
Hard Disk Drive Controller failure on bootup.
A. If you are using an IDE hard drive to boot, ensure that the power connector and the ribbon cable
are properly connected.
B. Check that the drive is configured properly as Master or Slave by jumpers on the drive.
C. Check that the HDD parameters are set up correctly in the CMOS Setup. (You can use auto-
detect on the hard disk to find the correct HDD parameters.)
When booting, the SCSI BIOS banner does not appear.
A. Either the onboard SCSI is not enabled in CMOS or no interrupts are allocated to PCI devices
in the CMOS chipset setup. At least one IRQ must be allocated for each PCI device on the bus.
You can get an extra IRQ by disabling a jumper at JP1. However, when you disable the jumper,
you will not be able to use a mouse with your system.
Non-Plug-and-Play ISA card is not functioning properly.
A. If this card uses an IRQ, make sure that the particular IRQ is reserved to the 'ISA' bus in the
CMOS chipset setup.
When booting, CPU reports No ROM BASIC.
A. The system cannot find a proper bootable sector on either drive A or C. You need to install an
operating system on the hard drive or insert a bootable diskette in the A drive.
When booting, system gives eight beeps.
A. These beeps indicate a video adapter problem. Try the video card in a different slot.
B. Try a different video card.
C. If you are installing an external video card, check whether the CPU has onboard video. If it does,
you need to disable the onboard PCI video in the CMOS chipset setup before installing the
external video card.
D. If the problem persists, clear CMOS and reflash the BIOS as discussed in Appendix A.
