- Let me start by saying that this was a good example of how to describe a
- problem, how to test for it, and what you did to isolate the problem
- component. I'm going to keep the test programs around to test any new
- machine I want to use, even though I've had no problems.

- | As a last try I went back to my dealer and after he made me a good
- | price, I changed the board for an Intel 486DX, 33Mhz, 256KB cache,
- | C&T Peak chipset. And now Linux works fine on this even much faster
- | machine. I stopped the gcc/groff test after 4 hours of running without

- My thought was a heat problem. I could rule out your case since it
- failed in your friend's machine (nice to have a friend who will swap a
- motherboard with you), but the second possibility is that you had the
- chip in a different place which got less cooling in both cases. I would
- have suggested cooling the CPU with a hair drier set on cold air
- setting, just to test the hypothesis. I would recommend heating the chip
- because of possible damage (although I might do it on my own system).

- | I also want to know what was the reason for this kind of errors.

- |
- | - Is there anybody out in the net using Linux on a configuration
- | similar to my old one? Please try to run the above tests and tell me
- | if it worked...
- |
- | - Are there differences between AMD 386 and Intel 386? Has the AMD
- | probably some bugs?
-
- No bugs I've seen (other than POPAD which is in Intel chips, too), and
- they generally run a bit cooler. If you can remember the placement of
- the CPU on the board, you might confirm that it was or wasn't different
- from the board which works for your friend.

- I admit that when I was in school I wrote COBOL. But I didn't compile.
