Expansion cards connect to the motherboard.
The Compaq Deskpro is a desktop computer that uses a Pentium III or Celeron CPU and runs Windows 2000. Although old technology by today’s standards, the Deskpro is very expandable. Learn about the different types of expansion cards in a Deskpro and the expansion slots available to get a better idea of what upgrades are available to extend its useful life.
PCI Expansion Cards
PCI slots are white and sit on the lower-left corner of the motherboard.
The Compaq Deskpro contains two Peripheral Component Interconnect (PCI) slots for modems, video cards, drive controllers and other expansion cards. Note that the Deskpro contains a Sound Blaster PCI 128 Audio Sound Card that takes up one of the two PCI slots.
The Deskpro contains two dual purpose PCI/ISA slots. As the name implies, these slots work with either PCI or older Industry Standard Architecture (ISA) expansion cards.
AGP slots are for video cards only.
The computer also contains one Accelerated Graphics Port (AGP) slot for video cards. Although you can also install a video card through a PCI slot, AGP provides more bandwidth for powerful cards. Install an AGP card if you play video games or use video-intensive applications.
Note that depending on the configuration of your Deskpro, it may already have an AGP video card. Some models come standard with a Matrox Millennium G400-SG or AGP Rage Pro Turbo AGP card. Others use an integrated Intel 3D graphics chip that sits on the motherboard and does not occupy an expansion card slot.
