Plug and Play spreads the burden of resource management
between the BIOS and chip set, the operating system, and the
manufacturer of the add-in card or chip.
With PNP, the installer simply plugs in the card, turns on the PC,
and lets the BIOS, chipset, and operating system determine the
resource requirements, then assign them.
Thus, the PNP compatible BIOS assumes the role of resource
manager. It is responsible for configuring PNP cards and system
board devices during the Power On Self Test. Once the POST is
complete, and the operating system starts up, it becomes
responsible for managing PNP devices with the BIOS providing
run-time services for the operating system.
Ultra PCI/ISA Riser Card
You can install a half-size PCI or ISA expansion card in the Ultra
workstation by using the optional Ultra PCI/ISA Riser Card. See
