Does F12 enable PXE booting or some such? I can't really tell from your e- mails exactly what the difference in the two cases are. The BIOS doesn't really tell the boot code much of anything. It just loads the first sector of the disk into RAM at 0x7c00, puts the BIOS drive number (typically 0x80) into the %dl register, and starts executing the code it just loaded. Unless hitting F12 is somehow booting from a different physical drive (and thus either loading different boot code or passing a different value of %dl to another copy of the same boot code), it shouldn't make any difference. -- John Baldwin _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
