Hello, I encountered a weird problem when installing FreeBSD 4.3-RELEASE on my AMD K6/200MHz machine. During during the initial boot the kernel panics due to a segmentation fault. I have booted and installed from a known to work CD-ROM so it's not a corrupt floppy set or anything. After a lot of trial and error I got it installed by disabling the CPU internal cache in the BIOS. It now runs, but with a severe speed penalty. This is ofcourse a far from perfect solution. I am unsure of the cause. The same system has run Windows 98 (with CPU internal cache enabled) for 3 years, so I think it's safe to rule out hardware bugs/misconfiguration. Some questions: - Is there something the FreeBSD kernel does with the CPU internal cache? - Would building a kernel for CPU_I386 fix the problem? If memory serves me, the Intel 386 had no internal CPU cache?
