I have an hp pavillion ze1250 with Debian Etch installed.

I am trying to play an online java game which has recently updated to a new high detail graphics mode.

Now the game says this new detail mode requires a 64mb 3d graphics card.

I don't really have a card I have integrated graphics chip, like this:

S3 Inc. VT8636A [ProSavage KN133] AGP4x VGA Controller

the card uses 16mb of shared memory, it says it can be adjusted anywhere from 8 to 32 megabytes.

so, my question is this:

can I make it 64mb somehow , or can I at least make it so that the website I'm trying to play on can read my card as having 64mb?

is there anyway I could make this work?

replacing the computer is not going to be an option

thank you

Not really, Linux won't improve your hardware. The adjustment you speak of is probably done in BIOS on your machine. Assign 32mb of your RAM to video, and if necessary specify this amount in kb in your xorg.conf. I'm not familiar with S3 xorg configuration but post your file(xorg.conf) here.
I think it should be something like a "VideoRam" line in your Device section.
I have no idea how your java game detects the video memory amount, so no clue as to how to fool it. Perhaps you will get away with not doing anything about it.

If it is possible on your computer, you can use AGP aperture memory. This resembles like level 2 video memory, so the latency will be higher. Also memory bandwidth will suffer. In a sense, using aperture memory gives you more video memory. Though performance will suffer because AGP is a one way street per operation and not enough memory bandwidth to handle the load.

It is best to get a new computer since the possibility of buying an AGP card is getting scarce.
