I see it is the VM/S version, and not the Asus O.E.M. version above.
My thinking is the motherboard was made for a proprietary computer manufacturer.
Perhaps NEC or Packard Bell.
Using this line of reasoning, it is my contention that the graphics expansion slot is the same, and motherboard chipset; for the VM/S version, as well as the Asus OEM VM version.
Graphics Expansion slot -
AGP and 8X........AGP 8X
SiS 661FX - Northbridge chip
SiS 964 - Southbridge chip
So we know the motherboard will support an AGP 8X graphics card.
Another item you need to have knowledge of, is what is the Minimum power requirement; for the particular AGP 8X graphics card you are looking at......
Let's look at some examples,
(They are getting fewer, and fewer; as the graphics card technology has gone to PCI Express.
PCI Express has evolved to the PCI Express 3.0 technology now)
Scroll down to - Features
-> Minimum PSU Wattage requirement
(Ignore of you are aware;
PSU = Power Supply Unit
The Power Supply's used in personal computers are SMPS.
Switched-Mode Power Supply)
MINIMUM power wattage requirement for the above AGP 8X graphics card, is 250 Watts.
Something I would like to impart;
Back in the day Power Supply manufacturers 'fudged' the True, Actual maximum wattage rating.
Actual maximum wattage rating, was more like 60 to 70 percent of what was stated.
If we use a 250 Watt PSU from back in the day, as an example; actual maximum rated wattage would be 150 Watts, to 175 Watts.
250 divided by 10 = 25
25 times 6 = 150
25 times 7 = 175 ]
DO NOT under power a graphics card!
A) It will not work right, or at all.
B) It will burn;
The gold plated contact pins on the bottom of the graphics card.
The contact pins in the graphics expansion slot.
Takes a while usually, but when done you can use the motherboard for a Frisbee.
Here is a Power Supply Wattage Calculator,http://extreme.outervision.com/psucalculatorlite.jsp
Takes about 2 seconds for the page to fully load.
Need guidance in using it post back in a Comment.
It is the 'Rule of Thumb', to have at least 10 percent more power, than what is required.
Easier on the Power Supply, as it doesn't have to strain to keep up.
I myself would recommend a 350 Watt power supply, at least.
One more thing if I may;
LOAD THE SOFTWARE FIRST!
Load all the software that comes with the graphics card.
It will be on the Installation disk that comes with it.
You will be loading the Drivers, and user interface.
For a graphics card utilizing the ATI (AMD) technology, you will be loading Drivers, and the Catalyst Control Center.
For a graphics card utilizing the Nvidia technology, you will be loading Drivers, and the Nvidia Control Panel.
AFTER doing so, THEN turn the computer off, FOLLOW Anti-Static Procedures, and Physically install the graphics card.
Because when a device is installed on a computer that has Windows on it, Windows will 'break it's neck', to find suitable, matching drivers.
If THE drivers are not already there, Windows will match up one of it's THOUSANDS of generic, one-size-fits-all drivers.
This = No
A Driver conflict can result........
Windows: "Which drivers do I use?
These or THESE?"
