>Description:
When choosing to do a custom installation, when I was presented with
the FDISK menu, I received a really weird dis geometry for my SCSI
disk: 1028 cyls, 255 heads, 63(?) sectors per track, giving me
an 8 gig drive. The drive is a micropolis 1528, adaptec controller.
The real geometry is 2100 cyls, 15 heads, 84 sectors/track. I tried
to enter the value, but the fdisk program insisted I was completely
whacked out. I tried several times, always with the same situation.
I finally gave up and tried the "novice" installation. Oddly enough,
the fdisk program sensed the appropriate geometry, and I was able to
fdisk and partition the drive with no problem. I'm now installing
from CDROM.

Note: when I was getting the bad geometries, during the boot I saw
the correct geometry printed out by the driver, so I know something
knew the correct disk geometry. It seems that fdisk was the weird
one....
