I was working on setting up a small lab in my room with some older 486 machines running linux to help me with some of my school work and other things to be automated to make things easier.

The main machine, has a 100mhz Intel and for some reason,I can not get any video to show up on at all.

I have tried 2 or 3 different cards all with the same result.

I believe the mobo is bad. If anybody has any pre-pentium hardware that they dont want, just lemme know.

Is there any chance to savethis mobo?

Hi have you removed the bios battery and left it for 1/2 an hour then retried the mobo.

Hope this helps

Does the PC Beep during the boot?
Does it have a mono / VGA jumper on the motherboard?
Do you have the manual for the MB?
Have you tried another monitor?
Are these video cards ISA or VESA?
How many cards are in the PC.
Have you tried removing everything except the Floppy and booting?
Have you got the feeling yet, that these questions are troubleshooting hints?
Regards, Chris

If you dont know what model and make your motherboard is check out this website,
http://www.motherboards.org/moboidtools.html
from here you can do 2 things , 1 download CTBIOS 1.3 put onto a floppy and run it on what ever machine it will give youa report on what your M/B is and then go to the respective website and down load the manual for it , or 2 just enter the bios string and you can get the information there on the web and then go for it as for CTBIOS 1.3, hope this helps you , you also want to chect the Motherboard VERYCAREFULLY as you might have bent one or more pins over in the ram or isa slots ( this has happened to me , i had the same simptoms )

More developments. I changed the mobo out for another one that I had onhand. Now, what I get is something quite different. Now I get 2 beeps in quick succession, then a series of more beeps that went too fast to count, then a short pause, and 2 morebeeps. The screen does not show anything, but I get a flicker once or twice. (Tried starting several times) I tried switching out the HDD and I changed the CPU from the 100mhz one I wanted to use, to a 66mhz one just to see if it was the CPU. The video card is good.

I would have taken the battery out, but it is quite well stuck on the mobo. Somebody had the bright idea to glue it on. I have all the same hardware in now as I did before, the only thing different is the mobo.

Any suggestions? I am having trouble finding the mobo manual for this board, but I think it was made by UMC. The one I was using previously is a SIS board.

Suggestions?
