I've spent this night trying to install FreeBSD 6.0 on a ThinkPad X40 notebook. The problem is, I've got it without any removable storage so I first tried to boot from the USB memory key.

I've build a bootable USB key with FAT filesystem using utility from HP (http://h18007.www1.hp.com/support/files/hpcpqdt/us/download/20306.html). Then I copied the contents of the bootonly ISO and contents of ftp://.../pub/FreeBSD/tools/bsdboot to it, booted DOS and entered:

tools\bsdboot -f boot\kernel\kernel

This started the boot proces which printed some numbers and crashed after two or three seconds.

If someone has any idea what could be wrong, how can I do it another way or something, I'd be very glad to hear about it.
