I have a Toshiba Sattelite A105 S4064. Sadly, this laptop only sports the Intel 945GM chipset graphics control, integrated onto the laptops mobo. supposedly, I should be able to adjust teh video memory ranging from 8mb to 128 mb, but in windows it shows 0mb dedicated video memory, 32mb of system video memory and 192mb of shared system memory. Furthermore, the bios on this laptop has no options to adjust the video memory availability. My question: Is there any way at all to up the video performance on this laptop? I have been unable to find very detailed specs on this model. is there an open slot on the mobo into which I can put in a new graphics card? can the video memory be adjusted? Anyone who is familiar with these models, please give me something to go with or at least get started in the right direction on this. Thank you!
