Upgrade the BIOS
If you need to update the BIOS because of a change in processor speed or cache
size, you will first need to remove any video option card installed and enable the
onboard SVGA controller in the SCU. Once the BIOS process completes
successfully, you can then enable and reinstall the video option card. You must
upgrade the BIOS before installing a second processor or processor module.
NOTE: The BIOS upgrade switch SW1-1 on the main
logic board must be set to ON before you can upgrade
the system BIOS.
Update the BIOS
Use the following procedure to update the BIOS:
1. Power up and boot the server with the BIOS Upgrade diskette in drive A.
2. Change the directory to "upgrade":
A:\cd upgrade
3. At the MS-DOS prompt, type
phlash
and press Enter. The following
message appears:
***Warning***
You are about to erase the system BIOS in this machine. Are
you absolutely sure? Press “Y” to continue.
4. Select "Y", and the BIOS upgrade continues until the system reboots.
NOTE: DO NOT power down the system once this procedure
has started. If the system loses power, or if at the end of this
procedure the system fails, refer to "Troubleshooting – Using
the Crisis Recovery Diskette if Necessary."
5. Remove the diskette from Drive A.
