I recently completed building my new computer using a Tomcat i845GL-S2098
motherboard.

Then I installed Windows XP from my CD. Everything went very well! XP worked
fine!

Since the CD did NOT include SP2, I installed SP2 from another CD.

After SP2 was installed, my problem occurred. The display resolution was
reduced to a minimum. Furthermore, I could not change it using Control
Panel/Display in the usual fashion. (Weird!) In fact XP "knew" that the
display was "messed up" since there was an icon and message in the lower
right  in the notification area (systray) stating so. Also, device manager
had a large yellow question mark for the video controller.

Thus my "VGA was wiped out".  Since I had not installed networking (which I
intend to do later on), I used my other computer to go to the TYAN site for
a VGA driver. Since the driver info on the site was the same as that on the
CD that came with my motherboard, I used the latter in the hopes that I
could load the correct VGA driver. After I did so, I got an Icon in the
notification area about the driver. I right clicked on an associated option
and made a selection. Unfortunately, the screen went blank. Not even a
CTRL/ALT/DEL nor subsequent rebooting of XP would change the blank screen. I
was "dead in the water as far as XP was concerned".

So, I decided to start over. I booted from a my disk utility CD and deleted
the (single) partition that contained XP and created a new (blank)
partition. It will take my less than 1 hour to reinstall XP (without SP2)
from the XP-install CD. However, I need to PLAN how to upgrade it to SP2
without the above mentioned problem (or being able to correct it). That's
where I need advice. I assume the same problem will occur when I install SP2
from the CD. WHAT do I do to get the "display back to normal". It would be
nice if I could just have a floppy ready that contained the VGA driver files
in a format the I could appropriately input.

Any suggestions?
