the Preview Release is not our newest release and has known problems. I
recommend you upgrade ot 27bz-7, or wait for the new release which
should be out soon.

It's the size of the ramdisk

If you don't mind booting from floppies or cds and aren't using the
harddrive, then you don't need to run beofdisk.

Looks like it might be a driver issue. I had problems with that same
card with the 2.0 preview release, but it worked fine with 27bz-7.

From what info you've given, it looks like you did everything right.
The only problem is needing to upgrade the software.
