m/b is MSI MS-7008 v1.0A
cpu Intel P4 2.95GHz
RAM 1Gig
AGP card is Apollo GeForce MX4000 128MB DDR 4X/8X.
Video driver is nVidia latest (Aug2005) downloaded and installed.
Using CheckIt Diagnostics reports (0) memory under video heading.
I am a bit confused by the daul screens nVidia desktop manger displays. Seems the AGP card has TV/out built into it which I may never use.
How do I get the 128MB of video memory recognized by the system?

Is the vga card being used? Then you are using its video memory. I would be thinking its a problem with checkit rather than the card.

Many card manufacturers have software which tests video cards - see if Apollo does - if not look for something shareware.

If the second monitor is not enabled, it won't use any Video RAM.

The card has to use its own RAM.

I would be going with James here as you only have to option to use the AGP Card to get a display it is obviously working so the most likely culprit is the software being used to check the system.

While this may have worked previously with the latest Driver upgrade or some new Windows Patches could have disabled some functions of the software. On boot-up you should be shown the Video Card type and Memory Size so if that is working OK and showing the 128 MEG the Video card is working properly but the software isn't reading the Cards Memory.

As for the second monitor showing up on the Display settings unless something is connected it will not be using any resources but as I can not quickly find the makers web site these cards are generally a Dual Head card with a standard VGA socket and a DVI socket so you can connect two monitors to the one card to extend your desktop. A lot of the new Thin screen monitors like the LCD, TFT use a DVI connection but you can get a DVI to VGA adapter for a conventional CRT monitor. But if this socket isn't connected to anything it will not be using any resources. What you can do with the second monitor when activated in the display options is to place the mouse pointer on it and drag it to where you want it left, right, top or bottom of the master monitor you can not drop it on top of the existing monitor to have 2 monitors displaying the same images but you can have it setup so that you have 2 monitors with different images on each.

Are the BIOS settings correct?
Esspecially something like "Primary Video Adapter" must to be VGA not PCI

I just got a tidbit from MSI that Win98 does not support more than 512Mb ram and may be a factor in this problem.
I have sent the video card back for replacement.

I am confused by your post about the memory available to Win 98, and the card being sent back.

Going back to first steps.

If you have a AGP video card, it has RAM on it, and there is no sharing of RAM. If you use a video display built into a chipset on the motherboard, they often share RAM with the system's RAM.

The fact that Checkit doesn't find it, means in all likelyhood that there is a problem with checkit, not the card itself. If the video card had a problem with the memory on the card, you would experience system errors and failures.

Sept 20th, 2005 I am removing Win98SE to install Win XP SP2. After I get XP up and "stable?" I will try the AGP card again. Confirmation of unrecognized video memory came from another program; "Tiger Woods PGA Tour 2005." It will not work without at less 16Mb of video ram. This question will be ongoing. Thank you all for the 'heads up' on so many issues.
