But if you are doing a re-install and the MB was previously set up it may have advanced settings active in the bios. Those settings need MB drivers loaded in windows to work. The drivers are not yet installed so you get a conflict. XP/2000 handles a lot of this for you. 98 does not.
Try setting bios to "defaults" before you start the windows load. If you can't get into bios you can reset bios to default using the jumper on the MB. Do the MB jumper reset with power off.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
