Problem with SCO UNIX 3.2.2 Installation

[sys0001 at dircon.uucp]

I'm having a problem installing the new version of SCO UNIX 3.2.
The N1 disk is marked Release: 3.2v2.0s.

What's happening is that when I start the installation process, by
booting off disk N1 and then disk N2, my system does a full reset
while it is displaying the configuration information on the inital
boot screen. 

The last diagnostic letter to be displayed is G. About 1/2 a second
after G is displayed, the machine performs a hard reset. There are
no panic or other messages displayed. 

I'm using a Wyse 386 16Mhz PC, with the Adaptec 1542B disk controller and
a Wren VI SCSI disk drive. The PC has almost 6Mbytes of RAM. There are no
other cards installed in the system (apart from the Wyse EGA adapter, running
on a mono screen, and a Wyse serial port).

Previously, I had the old Version 3.2.0 of SCO UNIX on this machine. 
It originally installed with no problems and has booted up everytime since
without fail.

One difference I have found between the old and new version is that
in the list of configured devices which comes up on the boot screen,
a SCSI tape drive seems to be already defined in the new version. The 
old version did not have this defined. Currently I do not have a tape drive
for this machine.

Note this is not an upgrade...I am installing the new UNIX version
from scratch.

Has anyone come across this problem? Is there a fix?

Thank you in advance for your help.

Regards, Ben
