Steven,

You know, I've responded to this twice and so far my answer has not
shown up on the list.

Basically, check the LBA/Normal/whatever setting for the drive in
your BIOS CMOS setup area.

DOS can't see certain disk geometries (essentially a cylinder count
limitation).

Let me know if you get this.


Cheers,

~~ Garry
