I'm having trouble to install NW 6.5 SP5 on a Dell PE1950 server.
The PE1950 has 4 SAS disks and a PERC5/i Raid ctrl.
There is no problem to boot the server from the NW OS CD and run the
But when the server reboots after installation it will not boot from the
DOS partition.
I get this message:
loading Bootstrap...
Cannot load DOS press key to retry

I've also tried to install MS-DOS 6.22 on the server but the problem is
that FDISK will not find any disk.

Any ideas on how to resolve this problem ?
