Drive Geometry fail

[Matiss]

Hey all,

Installing FreeBSD 7.0 on Intel Server Board S3200, WD HDDs 750 GB,
it gives me this "A geometry of yadayadayada is incorrect, using a
more likely geometry" error.

Of course, in the past I usually just pressed ok and all
installations were fine. Till today.

It gets to install and then starts to complain that it doesn't have
any inodes free. 

Now, my bios on this motherboard doesn't give out what IT thinks the
geometry is, so I'm hosed there. 

Basically I have no idea how to get FreeBSD moving on that box. 

Any advice? :)
