The way out is to run pfdisk under DOS to see what the number of cylinder/heads/secs-per-track information is and then feed that to the FreeBSD install when it asks (overriding the bogus defaults that it comes up with). You can also get this information straight from FreeBSD by booting the install disks and saying "n" to the first "Do you want to install?" prompt. Then do an `fdisk /dev/rsd0d' if you're SCSI or `fdisk /dev/rwd0d' if you're IDE/ESDI and take a look at the numbers printed out for the overall disk geometry (note: Do this BEFORE you've installed FreeBSD for the first time or it won't work). Then re-run the install script and plug those values in. Good luck. Jordan
