I should have saved the first sectors.. but I have to get a test system up
to try out ISDB4BSD and ..

Right after the standard install of 1.3.3 (before erasing the first sector
of the disk), the machine just locked up when it was supposed to start
loading the kernel.  No messages were printed by the bootloader.

After erasing the first sector and doing installboot, the system didn't lock
up, but I saw a request to insert a bootable floppy in the drive (this was
actually a nice animation from the IBM BIOS :-)

Then I erased the first megabytes of the disk and did _exactly_ the same
install as before, rebooted - and it worked.

Hmm.. I may have used "/dev/wd0d".. I think I used "/dev/rwd0d" on the
second time.  Anyway, erasing the disk before install _did_ help.

I guess I should be running fdisk all the time, not installboot, then?
