How Data is configured
The BIOS provides a Setup utility in ROM that is accessed by pressing <Del> at the
appropriate time during system boot. Setup configures data in CMOS RAM.
BIOS Upgrades
A new version of the BIOS can be upgraded from a diskette using the utility that is
available from Viglen. This utility does BIOS upgrades as follows:
?
Updates the flash BIOS from a file on a disk.
?
Updates the language section of the BIOS.
?
Makes sure that the upgrade BIOS matches the target system to prevent
accidentally installing a BIOS for a different type of system.

Plug and Play: PCI Auto-configuration
The BIOS automatically configures PCI devices and Plug and Play devices. PCI
devices may be onboard or add-in cards. Plug and Play devices are ISA add-in
cards built to meet the Plug and Play specification. Auto-configuration lets a user
insert or remove PCI or Plug and Play cards without having to configure the system.
When a user turns on the system after adding a PCI or Plug and Play card, the BIOS
automatically configures interrupts, the I/O space, and other system resources. Any
interrupts set to Available in Setup are considered to be available for use by the add-
in card.
PCI interrupts are distributed to available ISA interrupts that have not been assigned
to an ISA card or to system resources. The assignment of PCI interrupts to ISA
IRQs is non-deterministic. PCI devices can share an interrupt, but an ISA device
cannot share an interrupt allocated to PCI or to another ISA device.
