How to increase memory for ATI X1200 graphics card?

hey y'all, i just got a new toshiba A215-S7444 laptop with a 1.9Ghz AMD Turion 64 X2 processor, 2GB DDR2 RAM, ATI X1200 and a lotta gud stuffs. You see, I was happy getting this baby cos of one thing...the graphics memory has an onboard 128MB and can share up to 703MB from the system giving it a total of about 831 worth of memory. Now I installed Halo 2 for Vista and guess what?...it runs so horrible that I can barely type or move anything! The system says my graphic card memory size is 831MB but also says that my system memory is 1.8GB. I know that if it's really sharing it, I should be left with about 1.2GB of system memory. Does anyone know anything about this? How can I manually share my system memory? Oh yea...I already tried using the BIOS menu and the setting is not there. Is this a known issue? Am running Vista Home Premium. Does anyone know anything about this or is it just me? Thanks...

1. Laptops were not ment to be gaming computers. Do yourself a favor & build a desktop or buy an XBOX or PS3.
2. While what the previous poster said was correct, it is not the entire story.. I would recommend downloading some low-left system analyzers to see how your system is allocating.. In addition you could always benifit from overclocking... Especially your Ram...(not in size but speed) ... If you would like assistance...Feel free to drop me a line.
