BIOS Upgrades
Because the BIOS is stored in a flash memory device, you can easily upgrade the BIOS without
having to disassemble the system. The flash upgrade process can be accomplished by running a
utility from a diskette, a hard drive, or over a network.
The section on Flash ROM in Chapter 2, "Compaq Utilities," explains how to run the BIOS upgrade
utility.

1.3.10 Expansion Slots

The computer has two dedicated 16-bit ISA-compatible slots, two dedicated PCI-compatible
expansion slots, and one "combination slot" that can be used by either a PCI or an ISA board. For
more information about expansion slots and installing expansion boards, see Chapters 5 and 6,
"Removal and Replacement Procedures."

1.3.11 Power Supply

The power supply provides power for system requirements including onboard resources, expansion
boards, and drives. The desktop system supports a maximum of 145-watts of continuous power. The
minitower system supports a maximum of 185-watts of continuous power. The same power supply,
rated at 200-watts maximum output, provides for both system requirements. The power supply has
integrated surge protection to withstand a 2,000 volt power surge. A switch on the computer back
panel sets the power supply to operate at:
115 VAC (in the range of 100-120 VAC)
230 VAC (in the range of 200-240 VAC)

1.3.12 Diskette Drive Interface

The diskette drive interface is 8477 compatible and supports two storage devices (diskette or tape
drive).
