It sounds to me like your problem is not related to the 1GB restriction. That
restriction doesn't prevent the disk from being seen at boot time, it will
just cause the disk to be trashed sometime later.

One thing you might check - the Fujitsu disk supports synchronous SCSI,
the DECstation (with Ultrix 4.1) doesn't. You can set a jumper on the drive
to disable synchronous SCSI. You should also set the SCSI-1 jumper.

When you partition the disk, make sure you don't use the whole disk. You
can use up to 1Gb, but no more. That translates to 2,097,152 sectors that
you can allocate with chpt. If you don't follow this restriction and try
to use the whole disk, the disk will end up being corrupted.
