If the error he's getting is what I think it is, the fs may as well be
screwed, it'd take a massive effort to straighten it out. The problem
seems to be bytes getting juxtapositioned, and you can see what a mess
hdparam may make if its doing this already... It looks almost like
being in 16-bit mode causes the thing to make screwups ala "middle
endian" byte order.

Just for kicks, you can set the number of cylinders to ONE on your
hard disk, if only Linux partitions reside on it. Since Linux uses its
own drivers for this, and LILO resides on the first track, it actually
works. Great for confusing people (Huh? You have a 504KB hard disk and
it holds all that??)
