ok.. Now to rattle your brains a tad :) Since I'm a computer techy myself i can't even work out this prob. This Pentium 90 mainboard is equpped with 16Meg ED0 (working) memory, 1.28 gig IDE HD & 1.44 Meg floppy/cable. After booting it freezes at the config screen (after the POST). To clear things up and to make things easier, i disconnected the HD , so just running from floppy, and altered the Bios accoringly to boot from A:. After the POST goes though, the config screen halts. Relizing a number of issues, I made sure memory was seated properly, cables was in to floppy onboard controller and disk drive. Still nothing, so tried replacing memory with "well known good" working ED0 sticks (64Meg actually). Didn't fix the prob. CPU swap with a P75, and jumpered accoringly didn't fix it either. Decided to test a POST diagnostic card in it. 4 PCI, 5 ISA slot system. In the PCI slot it reported 7F with either the 16 aor 64 Meg ram in. While in the ISA slot, it came back with 7A. Any clues ? As this mainboard used to work perfectly before.

What OS were you running on it before. W2K needs 64K RAM, 133MH Processor and looks for 2G hard disk space. Could this be the cause of your troubles? ChrisE

I think he means 64MB of RAM... anyway, why try to use W2k on a P90? That is not even the minimum listed... http://www.microsoft.com/windows2000/professional/evaluation/sysreqs/default.asp Also, did you check the compatibility of your BIOS and other hardware? http://www.microsoft.com/windows2000/professional/evaluation/sysreqs/default.asp Could be a BIOS problem. What type of boot floppy are you using? Have you tried to boot with a Win98 disk?

Ooops! Well spoted Paul. ChrisE

Does the diskette drive, seek and try to access during POST? You may have to enable the diskette seek test in CMOS setup. Does the machine try to boot from the diskette? Any beeps? Have you hooked up a speaker? Most likely cause of failure at this point would be problems with the diskette attachment or with the DMA logic on the system board. Could there be a short on one of the PCI/ISA bus pins somewhere.

true. .. I wasan't running 2k on it at all. just win98se on the drive before. I should really buy a internal speaker to test it, as my previous internal speaker broke. Could be the DMA yea, but wouldn't the POST card tell u this ? All it comes up with is FF and/or 7A. I mite just add these two codes on the POST card only show up if the comp. doesn't even POST, which is on occasions. Why would the win98 boot disk make a diffence ? no drive light on at all except during the "seek" at POST. So in truth, after POST, it doesn't do anything, next screen (configuration screen) appears, and halts. (If just updated CMOS), then I do get the "Updated .....successfly" etc.. as u would do, but that's it. A speaker would be a good investment :) i think, coz i broke my previous one (by accident) := . Not only that, but it would only give ya the same codes, only it would be "by ear" not visually as a POST card would.
