Hello Jaspal,
You said that you *used* to have 1024x768, but you encountered
problems with norton anti-virus. When you removed the NAV, you still
have 600x800, at 16 colors resolution. I think what happened is that
you may have unintentionally deleted some of the vga driver files.
In order to remedy this, you went to the SiS website and downloaded
the graphics drivers for the SiS 620/5595. But despite of the SiS620
VGA drivers in being in place, you still could only get the same
640x480 resolution. You know why? There are some instances such as
this one that although you got the correct driver, it may not work on
a specific model because the manufacturer of the board made some
revisions. Bottomline is, no matter what software you uninstall or
whatever driver you install, if it's not the correct one for your
hardware, the problem will still be there or you may still have other
problems.
"We don't have the NT4 discs, because the service guys would bring
their own NT4 disk to fix any problems we used to have." -- Neither
will you find the correct driver there.
So in your case, you can get the correct driver, from PC Chips, your
mobo's manufacturer. It's found here:
PC Chips - PCChips.com
VGA driver for WinNT 4.0
http://www.pcchips.com.tw/vgadriver.html#VGA%20WinNT
You can simply download the zip file by right-clicking on the link
below and choosing "Save Target As...":
PC Chips - PCChips.com
M741LR(04/12/99)
ftp://ftp.pcchips.com.tw/driver/vga/winnt4.0/xcel2000.zip
Don't worry, although it says "xcel2000", the contents are actually
sis620 drivers. I checked it already. There are two versions inside
for NT3.5 and NT4. You need to choose NT4 of course. Unzip the
"xcel2000.zip" file to your desired location.
HOW TO PROPERLY INSTALL THE DRIVER
If the previous driver has an uninstall option, by all means, please
use it. Otherwise, you need to update the driver from the device
manager and point to thor better yet, remove or delete the device. You
will then need to restart. After restarting, you can then install the
driver that you downloaded.
I hope this helps you. Should you have any comments/questions, please
feel free to post your clarification before rating this and I'll
attend to you as soon as possible. Thanks for asking.
Search strategy:
Personal knowledge - I already know that M741LMRT is a PC Chips mobo
so I simply located the correct driver.

Hello Feilong,
Thank you for your response. I installed the drivers you found, but
still the problem remains.
I also noticed that when I reboot, there are 2 NT boot up options :
1) NT
2) NT (VGA mode)
I tried your solution in both modes, but the 800x600 just doesnt' want
to budge in the NT mode, and it defaults to 640x480 when I tried it in
the NT vga mode (and won't even reach 800x600)
Also, I have SiS Sandra 2000 installed (which gives me access to all
info on system, CPU, BIOS, etc.), and when I checked the video adapter
after your SiS 620 drivers were installed, the video adapter section
remained empty - ie.: the drivers were not recognized at all. When I
checked the adapter type in the display panel, it was only showing the
default driver info ('vga compatible display adapter'). Yet when the
other drivers were in use, the specific driver info was noted in the
display panel (ie.:SiS 6236).
Any further suggestions, or does it sound like a h/w fault?
Thank you again for your help.

Hi Jaspal,
First of all, thank you for making your clarification. The
installation of the driver I gave you is quite simple and should not
have given you any problem. I'm sure that the driver I pointed you to
is the right one for your Sis 620. It should have solved your problem.
Since the problem is still there, the following is what I think are
possible causes:
1) You may have incorrectly installed the driver. As I said, you need
to properly remove the 6236 driver you installed because it will
conflict with the driver I gave you. Perhaps you can ask someone to
assist you on the proper uninstallation of the 6236 driver and
installation of the correct driver to make sure that it is done
properly.
2) Your monitor's refresh rate is set to a rate that is not supported
by your display driver. Try setting the monitor the monitor to
"Adapter default" then try to change the screen resolution.
3) Your NT4 system has a problem. Perhaps some system files are
missing and/or may have been corrupted since the beginning of this
problem. Perhaps it's time to call your NT4 service guys to check and
fix your system and install the driver for you.
4) Although it's not likely, I'm not discounting the possibility that
this could be a hardware problem, given the age of your mobo. You may
be correct on this one. I saw the picture of your mobo in the PC Chips
website ( http://www.pcchips.com.tw/M741LMRT.html ) and noticed that
it has no AGP port. Since your display driver is built-in you have no
alternative option because the mobo has no AGP port and has only one
PCI slot which I'm quite sure is occupied by a card. If ever your
service guys come in, ask them to verify that your hardware is still
okay. If it is, the most likely cause of your problem is number 3 -
your NT4 system has a problem.
At this point, there's nothing I can do about it and I hope you
understand. Since I've already pointed you to the correct driver for
your mobo, it should have solved your problem. Since I can't
personally check your system, you can only have your service guys
check it for you. Again, thanks for asking.
Regards,
Feilong
