Which makes IBM ThinkPads & Desktops boot from a FreeBSD bootable CD. The problem is they expect to see a "MS-DOS" type disk header which {Open,Net}BSD and Linux have so things work. FreeBSD does not. I made an 4.3 ISO image with this patch applied to the boot code. Some people on this list have access to that. I did that at my former employer (IBM) they might be able to send you the ISO image. Yes it is a pain on some IBM machine in which it is difficult to have a floppy and CD device attached at the same time. Doug A.
