@jaxanim:
*Does* your PC boot from CD-ROM? If yes, then you won't need a W98 Emergency Disk to reinstall. If no, well..you guessed ;-).
And do you know what brand/type/part number the mobo is? Normally there should be some sort of marking on the mobo. Unless it's a very dodgy noname mobo ofcourse ;-). Usually mobo makers will have some software- and ROM- aka BIOS-updates available.
-edit-
Er...just like mikeymike said on the previous page ;-).
