There have been cases of 486 motherboards being bad. Here is some old mail:
1> The symptoms are that when he tries compiling, after a brief whir of the

1> His configuration is: Sonal PC, 486dx running at 33MHz with 4Mb total memory
1> (640k + 3.4M extended). It uses an AMI bios, dated 3/15/91 in the rom, which

2> DJ, do you remember when I asked you this lock up problem a while ago?
