In other words, you need the i586 cpu settings or it will not work. You can verify this by starting up comptest in DOS and instead of saying it is a 486 (as it usually does), it will say Pentium. Solution: Bootup with the generic kernel and recompile with i586 settings or leave the 486, 586, and 686 settings all in the kernel.
