Installing Accessory Boards
The PC has four accessory board slots:
• Slot 1 (the top slot) can be used for a full-length 32-bit PCI board
• Slot 2 can be used for either a full-length 32-bit PCI or a full-length
16-bit ISA board
• Slot 3 can be used for a full-length 16-bit ISA board
• Slot 4 (the “HP ISA Option” slot) can be used for half-length (XT)
16-bit ISA boards.
The bottom HP ISA Option slot accommodates different size ISA
accessory boards depending on the memory options installed in your
PC. See the following table.
Configuring Accessory Boards with Plug and Play
Plug and Play is an industry standard for automatically configuring
your PC's hardware resources and the accessory boards installed in it.
If your operating system supports Plug and Play, your PC has
configurable support for Plug and Play in the BIOS.
NOTE All PCI accessory boards are Plug and Play, although not all ISA boards
are. Check the accessory board’s documentation if you are unsure.
When you start your PC after installing an accessory board, the Plug
and Play BIOS automatically detects which hardware resources (IRQs,
DMAs, memory ranges, and I/O addresses) are used by the system-
based components.
1. XT width = 10.7cm (4.2”)
2. AT width = 12.2cm (4.8”)
