I had previously installed NetBSD 1.6 from CD to this system.
I gave up trying to upgrade to 2.0.2 via building sources.
I created boot floppy's and installed 2.0.2 via ftp. I did not reformat
the disk and used the partitioning that was created with the 1.6 install.

Installed bootfile doesn't support required options.
Update the bootcode from /usr/mdec/mbr_bootsel? [n] y
Boot selector configuration:
Timeout value (0 to 3600 seconds, -1 => never): [-1..3600 default: 10]
Select the default boot option. Options are:
0: The first active partition

We haven't written the MBR back to disk yet. This is your last chance.
Should we write new partition table? [n] y

Rebooting produces "Error ?" where I expect the kernel to load.
After rebooting from the install floppy and interrupting the boot
and selecting the hard disk it comes up.
