[comp.unix.i386] Problem with SCO UNIX 3.2.2 Installation

sys0001@dircon.uucp (08/14/90)

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

I had this same type of problem installing on my machine.  I had
to do with the fact that I had a CPU cache--386, 33MHz.  With
the cache controler turned on, right after the N1 disk was it, and
it should have asked for the N2, BOOM!  It reboots.  Turned off
the cache, it worked fine.  Turned the cache back on once install
was done.

However, you said you have a 386, 16MHz.  Well, I doubt that has 
a cache on board.  I found my answer by reading the vendors documentation
on installing OS/2.  It apparently would have had the same problem
as Unix.  Therefore check your docs on OS/2 installation to see if
anything special need be done.

We had really odd behavior on our SCO Unix installation, though ours
happened before the initial boot screen even appeared.  The cause was
incompatibility with the video board, a Paradise Auto-Switch 350.  We
switched to a True Blue IBM Monochrome board and everything worked
MUCH better.
