NOTE: According to the standard X86 structure, there is only 128 k (C0000h-DFFFFh)
shadow RAM for system option ROM. For this system, the RAID card option ROM
engrosses 64 k, the onboard A TI VGA card engrosses 32 k, the onboard LAN engrosses
more than 10 k, so the remaining space for option ROM is very limited. You may encounter
the possibility that some PCI cards (e.g., SCSI PCI card) cannot be initialized and used
when the PCI card needs more shadow RAM for its option ROM. When you encounter this
possibility, please close the onboard device you are not presently us ing temporarily
(disable the options under the Onboard Device Configuration sub-items on the BIOS
Setup’s Advanced menu (refer to Chapter 4 Advanced Menu).
6.3 Adding a Secondary Hard Disk Drive

following specifications. A hard disk drive that does not meet these specifications can cause
reliability problems in your system.
l Peak current draw: must not exceed 1.8 amperes maximum (at 5 volts) and 0.7 amperes
maximum (at 12 volts)
l Rotational speed: 5400/7200 rpm
l Interface: Ultra ATA66/100 (ATA133 for models supporting RAID)
l Operating temperature: must be able to operate in environments up to 55 °C
l Operating humidity: 10% to 90% (non-condensing)
l IDE and RAID IDE cannot be used at the same time
If you want to add a second hard disk drive, follow this procedure.
