I tried to use BOCHS to emulate a PC, and after going through all the settings, setting it to boot from CD-ROm. After starting the damn thing with Win98 Boot CD, I end up with the following:

00017694391i[CPU ] BxError: instruction with op1=0xff
00017694391i[CPU ] mod was 40, nnn was 7, rm was 3
00017694391i[CPU ] WARNING: Encountered an unknown instruction (signalling illegal instruction)

This just keeps repeating until BOCHS is closed.

Any idea on what might be happening? I tried to boot the thing from a DOS 7.1 bootdisk and it worked properly...

PS. The following was Bochsrc.txt I used:
