|There are 3 different Revisions of the mboard model. |
The Revision number of the mboard is printed directly on the surface of the mboard. e.g. Rev 1.1 or R 1.1
(That's NOT the same thing as the bios version number.)
List of the Revisions of this model on this third party site:
Choose the revision number of yours, and take a look there.
The specific cpu part numbers are shown on the left.
Also consult the PCChips web site. Look up the Cpu compatibility list for your model, AND the proper revision, if there are separate listings for the revisions. That list often also has information about which bios version the mboard must have in order to support the cpu you want to use.
If your present bios version is not high enough, you must flash the bios to the latest (non-beta) version when the system is working with a cpu it does recognize properly. Read the flash instructions there, usually found where the bios updates are. The safest way to flash is by using the bootable floppy method. If you choose that method, make sure the floppy has no undetected bad sectors BEFORE you place the flash files on it. Format the floppy (RIGHT click on A when the floppy is in the drive, choose Format). Don't change any default settings. When the format has finished, RIGHT click on A when the floppy is in the drive, choose Properties.
The capacity should be 1,457,664 bytes. If it isn't I don't recommend you use that floppy - it has bad bytes and it may develop more at any time. Try formatting another floppy instead.
