Appendix B. Updating the BIOS Firmware

This appendix provides information on updating the BIOS firmware.

BIOS Flashing

Follow these instructions to update the BIOS firmware:

  1. Obtain a DOS-bootable diskette.

  2. Unzip the BIOS flash package.

  3. Copy the following files to the diskette, and mark it “SGI 1100 BIOS upgrade, version xxxx”:

    • AUTOEXEC.BAT

    • AFLASH.EXE

    • M25xxxx.BIN

      Note: “xxxx” is the version number, such as “A1S4.”

  4. Enter Setup, and select the Boot Options menu. Specify “Floppy Disk A:” as the first boot device. See the SGI 1100 Server User's Guide (007-4337-001) for Setup instructions.

  5. Insert the previously-prepared diskette into the SGI 1100 floppy drive and reboot the system.

  6. Once the system boots into DOS from the diskette it will automatically run the AUTOEXEC.BAT file and then the AFLASH.EXE program. Then, after a brief pause, it will begin flashing the BIOS.

    Caution: Do not interrupt the system while the BIOS is being flashed.

  7. When the system indicates that the flash procedure is complete, remove the diskette and reboot the system.

  8. Go to BIOS setup, load the default parameters, save them, and exit.

  9. Store the diskette in a safe place for future use.
