Pentium era Mobo help

[RedDaemonFox]

I've a SuperP5MMS98 mobo, which i really like. It is AT form factor, but has AT and ATX connectors, SIMM and PC100 RAM slots, and plenty of jumpers for messing with voltage, speed multipliers, and bus speed. It had a place where a track had been cut when a piece of the PCB was nicked out of place. I fixed it with some solder, and the track is fixed. Now, I go to test it out. I put a Pentium MMX in there with a largish heatsink, put two SIMMS in Bank 1 (don't know the capacity), hook up a working AT Power supply and a Diamond Stealth 64, and.... NOTHING! No picture, an LED onboard keeps blinking steadily. Checked all cables, again NOTHING!!! Help me out.

If you are sure that the PSU is good then the next thing to check is that you have all the jumpers set correctly for the CPU you are using. Also try the system with just CPU and heatsink, I stick of ram, graphics card and PSU so you can rule out anything else. Also if this is the first time this CPU has been used with this board clear the CMOS as this might still have the old settings for a CPU that was used before, and this could be stopping the system from booting.

Not sure what a blinking LED means for that specific board. Would be good if you could track down the manual for the board to find out. In more recent boards I've found that flickering power LEDs on motherboards usually mean the PSU isn't supplying a good supply to the board, or the board is damaged and not working.

Help me out.

a please in your post wouldn't hurt!

try having a look here for the jumper settings http://www.elhvb.com/mobokive/Archive/S ... Jumper.htm

and here for the manual http://www.supermicro.com/manuals/mothe ... X_USER.pdf

to see if you have it set up right first and that the CPU is supported by your Mobo

If there's no onboard speaker, the LED flashes can indicate what the problem is. Have a google for your Mobo's error codes.
Are all your components known good?, TBH there are so many variables it could take quite some time to sort out what your problem is.

Well I'll dig a 64meg PC100 stick instead of two SIMMS. I'll check the jumpers again and check the MMX model. When the LED slow blinks, it seems it's in sleep mode. If my repair job wasn't good enough, I'll have to send it to someone who can fix the tracks. I'll be able to test it tomorrow.

Re: Pentium era Mobo help

Hey a small update: I reset the CMOS, checked the jumpers, and
put in a known good pC100 RAM and it still blinks steadily. I think it may be buggered.
