System BIOS
The system BIOS, from American Megatrends Incorporated (AMI), provides
ISA and PCI compatibility. The BIOS is contained in a flash memory device
on the system board. The BIOS provides the power-on self test (POST), the
system Setup program, and a PCI and IDE auto-configuration utility.
The system BIOS is always shadowed. Shadowing allows any BIOS routines
to be executed from fast 32-bit onboard DRAM instead of from the slower
8-bit flash device.
BIOS Upgrades
Because the BIOS is stored in a flash memory device, you can easily upgrade
the BIOS without having to disassemble the system. The flash upgrade
process can be done by running a utility from a diskette or hard disk, or over
a network.
The DOS-based upgrade utility (Flash Memory Update Program, FMUP) has
three main options:
•
Update the flash BIOS from a file on disk.
•
Copy the current BIOS code from the flash device to a disk file to
provide a backup if the upgrade cannot be finished.
•
Compare the flash BIOS to a disk file to verify that the versions are the
same and make sure that the system has the correct BIOS version.
Appendix A tells how to run the BIOS upgrade utility. For information
about the latest BIOS update, contact your service representative.
Plug and Play
Your system is fully Plug and Play compatible. Plug and Play makes it
easier to add components to your system. This feature provides these
important benefits:
•
PCI cards and Plug and Play ISA cards are configured automatically
•
IDE hard disks and main memory are configured automatically
•
Windows 95 Plug and Play ready
