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: s 115 VAC (in the range of 100-120 VAC) s 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). 1.3.13 Serial Port The serial port is RS-232C compatible. 1.3.14 Parallel Port The following parallel support modes are supported: s Bidirectional Standard Parallel Port (SPP) s Enhanced Parallel Port (EPP) s Extended Capabilities Port (ECP) Compaq Deskpro 2000 Series of Personal Computers 1-9
