Specifications

Compaq Deskpro 4000 and 6000 Series of Personal Computers 1-11
ISA Plug and Play Capability
ISA Plug and Play capability provides auto-configuration of Plug and Play ISA boards and resource
management for legacy (non-Plug and Play) ISA boards when used with Compaq’s Computer Setup
(F10 Setup) or a Plug and Play–compatible operating system like Microsoft’s Windows 95.
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, “Troubleshooting,” explains how to run the BIOS upgrade
utility.
1.3.11 Expansion Slots
Deskpro 4000 (desktop) with Pentium Processors with MMX Technology have two dedicated PCI-
compatible expansion slots, two dedicated 16-bit ISA-compatible slots, and one “combination slot”
that can be used by either a PCI or an ISA board.
Deskpro 4000 (minitower) with Pentium Processors with MMX Technology have four dedicated
PCI-compatible expansion slots and three dedicated 16-bit ISA-compatible slots.
Deskpro 4000 (desktop) with Pentium II Processors have two dedicated PCI-compatible expansion
slots, three dedicated 16-bit ISA-compatible slots, one combination slot, and one AGP slot.
Deskpro 4000 (minitower) with Pentium II Processors have three dedicated PCI-compatible
expansion slots, one dedicated 16-bit ISA-compatible slot, one combination slot, and one AGP slot.
Deskpro 6000 (desktop) with Pentium II Processors have two dedicated PCI-compatible expansion
slots, one combination slot, one dedicated 16-bit ISA-compatible slots, and one AGP slot.
Deskpro 6000 (minitower) with Pentium II Processors have three dedicated PCI-compatible
expansion slots, one combination slot, three dedicated 16-bit ISA-compatible slots, and one AGP
slot.
✎
The graphics controller resides in either a PCI slot in the expansion board cage, or in the
AGP slot on the system board.

“Removal and Replacement Procedures.”
1.3.12 Power Supply
The Pentium Processors with MMX technology-based desktop and the minitower computers share a
200-watt continuous rated power supply to provide power for onboard resources, expansion boards,
and drives. The Pentium II-based desktop use the 200-watt continuous rated power supply while the
minitower computers use a 260-watt continuous rated power supply. The power supply has
embedded surge protection to withstand a 2,000 volt power surge. A switch on the computer back
panel sets the power supply to operate at:
