To be exact: it does not run with 640 kB base + 3 MB extended memory. If your motherboard can remap some of the "lost" memory out of the 640kB to 1MB region, then you may still be able to get FreeBSD up. Try to go into your BIOS setup and look for a "remap" option. Enable it. You may also have to disable ROM shadowing. Regards, Georg-W. Koltermann, gwk@cray.com P.S.: Jordan, this is starting to become a FAQ....
