PCI Auto Configuration
IDE Auto Configuration
ISA Plug and Play Capability
BIOS SETUP AND MENUS
The motherboard's system BIOS is contained in a flash memory
device on the motherboard. The BIOS provides the power-on self
test (POST), the BIOS Setup program, the PCI and IDE auto-
configuration utilities, and the SCSISelect Utility.
The BIOS is always shadowed. Shadowing allows BIOS routines to
be executed from fast 64-bit onboard DRAM instead of from the
slower 8-bit flash memory device.
If you install a PCI add-in card in your computer, the PCI auto-
configuration utility in the BIOS automatically detects and
configures the resources (IRQs, DMA channels, and I/O space) for
that add-in card. You do not need to run the BIOS Setup program
after you install a PCI add-in card.
However, PCI add-in cards use the same IRQ resources as ISA add-
in cards. If you install both a PCI and an ISA add-in card, you must
specify the IRQ used by the ISA card. The PCI auto configuration
program complies with version 2.1 of the PCI BIOS specification.
If you install an IDE device (e.g., a hard drive) in your computer,
the IDE auto-configuration utility in the BIOS automatically
detects and configures the device for your computer. You do not
need to run the BIOS Setup program after installing an IDE device.
The motherboard provides auto configuration of Plug and Play ISA
cards and resource management for legacy (non-Plug and Play) ISA
cards when used with the ISA Configuration Utility (ICU) or a Plug
and Play compatible operating system like Windows 95. To obtain
the ISA Configuration Utility, contact your computer supplier.
