I recently got a P2 400mhz which came on some sort of server motherboard, the board is an Acer M11EJ. Whenever I turn it on it posts and checks everything no problems but when it tries to boot it says their has been an NMI issued, check event log. And when I check the event log in the bios it says that the NMI was a floppy A failure. I have turned floppy disk off, so it is told their isn't a drive and the floppy disk controller is disabled. Whenever I enable it same problem, and when I enable it with a working floppy disk it reads the floppy disk (win98 boot disk) for a while and then says floppy drive error, and when I continue then it says an NMI has been issued. I've tried changing the boot order to no avail. Can anyone help because this is driving me insane. Thanks

Did you try a diffrent cable? Is the drive correctly id'd in BIOS? The onboard controller could be bad. IF you have 98se you can boot from the CD-ROM

I've tried booting from 3 different floppy drives all of which I know are working. The drive isn't recognised in BIOS even though it can be read from. You can also boot from the original win 98 CD. But it won't let me it just comes up with the NMI error before checking any other drives.

Disable the floppy controller in bios, then try and boot from the CD

I have, but to no avail. Even when I disable it and change the boot order and put CD-rom first and floppy disk drive last. It still gives that error before it even attempts to boot from CD.

Are you installing the floppy corectly, drive after the twist, and not upside down? Never hurts to check the litle things, One time I got floppy error for about 1/2 an hour with no clue why till I realised I forgot to plug the power in.

yep, double-checked everything, the floppy drive works correctly and the Led turns on as it begins to read the floppy disk, but then it says floppy drive error and then the NMI is issued.
