Note this is fixed via pr-26382. 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.
