Hi,

I have a maxtor 120GB IDE disk on a Supermicro P4SBE mother board.
The bios reports the size of the hard disk as 
(Total size: 122 GB -- close enough!)

Cylinder: 58853
Head: 16
Precomp: 0
Landing zone: 58852
Sector: 255

FreeBSD 4.7 install reports the error message.

"WARNING: A geometry of 238216/16/63 for ad0 is incorrect. Using a 
more likely geometry."

It appears to be correct (although the bios reported different
values) when I refer to
http://www.maxtor.com/en/documentation/quick_specs/diamondmax_plus_9_quick_specs.pdf

So what am I missing? Is the BIOS wrong? I am already
at the latest BIOS (1.0c) for P4SBE
(ref: http://www.supermicro.com/TECHSUPPORT/BIOS/bios.htm )

Any help is appreciated.
