Question ID: 174776
I have a Pc100 SIS620 M748MR motherboard. I need to disable the 8 meg
video card so that I can upgrade it. I cannot change the BIOS, as they
are rights protected. There is only one jumper on the motherboard that
I am not sure what it is for, and it is labeled JOB. I cannot find the
answer at the website or the website. Please help

"I cannot change the BIOS, as they are rights protected."

Correct me if I'm wrong, does this mean that the BIOS is password protected?

Hello J9ison,

I did a careful search regarding your motherboard. Based on my search,
there appears to be two versions of the M748MR motherboard. The first
one I found supports a single Slot 1 processors. The second has dual
processor support for Slot 1 and Socket 370 processors. Since there's
no detail with regards to the type of board you have, I'd like you to
see if your board looks like the picture that appears on the page
below. Simply press the "Shift" key before clicking on a link so it
will open a new window or right-click on the link and choose "Open in
New Window" for your convenience.

Discontinued Generic Motherboards - M748(MR)

Here's one solution you can try:

You can find other relevant help for your motherboard through the link

I would like to reiterate that there seems to be two types of the
M748MR motherboard and as such, I'm expecting your clarification/s
before you rate this answer. Once you confirm and/or the initial
solution I gave you did not solve your problem, then we'll look at the
matter closely and find other solutions. If you find that the above
link/s solved your problem, please let me know.

My motherboard looks like the pic on the site that you
put up with your question clarification. I really am not sure what
"rights protected" means. I have had two people trying to help me here
in real life, to no avail.
Any other questions, let me know. Oh, btw, I have already tried the
PCI plug, which was your other link that you sent to me. Thanks

I'm glad one my initial answers helped you. I'm sorry for the delayed
response but I had to attend to urgent matters. I hope you understand.

Before I can proceed, I need to verify some things from you. I hope
you answer all my inquiries and provide me as much details as possible
in reply to my questions. The following are:

" I need to disable the 8 meg video card so that I can upgrade it."
Based on the picture from Eurocom LA, your mobo (motherboard) have
three PCI ports but don't have an AGP port (Accelerated Graphics
Port). If you're planning to upgrade it, you can only use PCI type
video cards. Are you sure you want to proceed? If so, are you sure you
have a PCI type of video card?

Personally, I think that this would be a bit impractical since your
mobo is quite old and you'd be shortchanging yourself by upgrading it.
PCI video cards just don't match the performance of an AGP video card,
particularly in speed and graphics rendering.

"I cannot change the BIOS, as they are rights protected"
Since you're not quite sure on this, I can assess the situation if you
can tell me what you intend to do with the BIOS. Do you want to flash
the BIOS and replace it with a newer version? - or - Do you simply
want to access it and change the BIOS settings? Where do you see the
phrase "rights protected"? Where does it appear?

I suggest that if possible, try to get a new mobo. The new mobos today
are faster, have features that are not found in your mini AT mobo, can
support larger disk drives and faster data transfer rates, and of
course, great product support. You should try to consider these
factors in the future.

"There is only one jumper on the motherboard that I am not sure what
it is for, and it is labeled JOB"
Don't worry, I already found the manual for your mobo. I'll guide you
later regarding this.

I'll wait for your reply. Thanks for your patience.

I have already updated this motherboard with more RAM and put a new
450Mhz processor in it. So, I'm already invested in this. The only
problem I am having is installing a new Exctasy PCI video card
(32meg). I cannot figure out how to disable the existing video card. I
have flashed the BIOS and tried updating it, but I still cannot
disable the onboard video through the BIOS. And, btw, the jumper is
labeled Jod,,,not Job. I have the systemboard user's manual, also.

Clarification of Answer by feilong-ga on 15 Mar 2003 12:56 PST
Thanks for your response.  Here's something you should remember about
disabling onboard peripherals (video or sound): No matter how many
times you flash the BIOS, if the onboard peripheral is enabled in the
BIOS and/or its driver is installed in the system, you cannot disable
it. Since you forgot to tell me what BIOS version you are using
(Award, AmiBIOS, Phoenix, etc.), I'll base this solution from the
manual that I have. Remember: This solution is based on an M748 mobo
with AmiBIOS.

First, you have to uninstall the driver of this onboard peripheral in
Windows. Make sure to uninstall -- DO NOT DELETE. You will be prompted
to reboot after this. In case not, you still need to reboot.

I'm not familiar with AmiBIOS but anyway, to access the BIOS, press
"delete" or "ctrl-alt-esc" after restarting. Go to the "PCI / Plug and
Play Setup" page and set the following:

Set this option to Yes if the operation system in this computer is
aware of and follows the Plug and Play specification. -- Choose "YES"

Set this option to select onboard AGP or PCI VGA card for primary
graphics adapter. -- Choose "PCI"

When this option is set to Enabled, multiple VGA devices operating on
different buses can handle data from the CPU on each set of palette
registers on every video device. Bit 5 of the command register in the
PCI device configuration space is the VGA Palette Snoop bit. -- Choose

In case you don't have AmiBIOS, try to look for menus similar to the
three I mentioned.

Save it your settings, restart, and insert your 32Mb PCI Video Card.
You will be prompted to install the device during Windows startup. You
only need to follow the instructions. If not, then install the
necessary driver. You need to restart afterwards.

Let me know if it worked.

Please bear with me. I am waiting for my computer expert to come over
and help me try your solution. Will get back to you in a day or two.
Thank you. Sorry for the delay.

Hi J9. How are things going on your side? Have you done it yet?

Not at all! I'm not thinking about that. I'm just worried because you
said earlier that it would take you a day or two and I noticed that
this time has passed hence my inquiry. Anyway, if you ever get it
done, just holler and I'll respond. ;-)

I really wish I hadn't even started upgrading this motherboard. My
computer keeps locking up on me, left and right.
Well, anyways, I will be trying this tomorrow, cuz my "expert" is
coming over tomorrow, I am pretty sure! I will let you know how it
works out.

Your answer would have worked but there is a conflict between the
video card and my mother board. I am sure your suggestions would have
been fine. Thank you for your speedy answers and your extensive

Thanks for the great reating and tip. Regarding the "conflict" you
mentioned, please understand that you are using an old motherboard and
a bit of compatibility issue with new hardware usually occurs. You are
on the right track and you only need to adjust settings in order to
get the correct one.
