I have a PI 166mhz system running redhat 7.3 that has been working as a gateway/firewall for about 18 months with no problems.

Yesterday it stopped working. When I tried to reboot I got as far as "Calibrating Delay Loop........" but no further.

I have changed the RAM, discinnected the hard disk etc all to no avail.

I then thought I would jsut re-load it. I can't even run the install, it stops at the same place.

I tried booting Knoppix but after setting the video mode nothing happens - jsut hangs, noerror messages no nothing.

Can anyone give me a definitive answer as to what is happening? Much googling has only produced the fact that a few other people have had similar problems and that it probably is a hardware problem.

TIA,

If you get memory errors first, and then you swap memory and still get errors, then you've got a bad CPU or bad M/B. Take your pick, but it's a clean fast way to eliminate some hardware.

i agree. i think something went out. but it could always
be anything, including the power supply.
like you tried, pull all the cards out that you don't need to
boot. look for buned places on the motherboard or any
cards.

Hi All,

many thanks to those who replied.

I did test memory but it didn't fail. I changed power supply with no effect.

I have given up. I have thrown it out and got a "new" PI-MMX 200 Mhz box (WOW!.....)

Thanks,
