This means your MBR is trashed.  It misses the usual signature
(0x55aa), so the BIOS ignores the disk as a bootable medium, and
proceeds to the next one.  If no bootable medium is available, it
tells you that you have no ROM BASIC.  That's a neat leftover joke
back from the old PC... ;-)

See whether your first sector has a useful fdisk table at all or not.
If so, simply recreating the bootstrap in the MBR might help.  This
can be done with ``fdisk /mbr'' under DOS, or with ``fdisk -i'' under
FreeBSD (boot the installation floppy, select `fixit', and enter a
fixit floppy).  You have to reinstall the boot manager later however.

What do you get back as a prompt here?  sd(1,a)/kernel _should_ work.
If it doesn't, it probably means your installation is seriously hosed.

I wonder how you did this...
