Can't boot NanoBSD on an Alix board

[Lyle Scott III]

i have used the Sandisk 512 line as stated earlier.. i have also specified
manually:
NANO_MEDIASIZE=1000944
NANO_HEADS=63
NANO_SECTS=16

... i will try to comment out the line that builds the bootmanager... even
if i add
# Number of code images on media (1 or 2)
NANO_IMAGES=1

it builds one image, but still throws the bootloader on there.

thanks for all the input!  i'll work it some tonight between studying for
exams... nanobsd doesnt exactly take 5 minutes to recompile :)
