Changing The Memory Amount Used For Onboard Graphics

Best way would be to purchase an actual graphics card and disable on board video :)

you can always contact them for your problem :

the setting in the bios is the minimum amount of system memory to allocate to video (for dos, legacy compatibility, etc). the system (operating system and drivers) will dynamically assign (and release) system memory as needed up to 64mb for < 256mb ram, 128mb for < 512mb and up to 224mb above that.

from an intel manual (technical reference for their own 915gl motherboard):

1.5.1.1 Dynamic Video Memory Technology (DVMT)
DVMT enables enhanced graphics and memory performance through Direct AGP, and highly
efficient memory utilization.  DVMT ensures the most efficient use of available system memory for
maximum 2-D/3-D graphics performance.  Up to 224 MB of system memory can be allocated to
DVMT on systems that have 512 MB or more of total system memory installed.  Up to 128 MB can
be allocated to DVMT on systems that have 256 MB but less than 512 MB of total installed system
memory.  Up to 64 MB can be allocated to DVMT when less than 256 MB of system memory is
installed.  DVMT returns system memory back to the operating system when the additional system
memory is no longer required by the graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS
Setup program) for compatibility with legacy applications.  An example of this would be when
using VGA graphics under DOS.  Once loaded, the operating system and graphics drivers allocate
additional system memory to the graphics buffer as needed for performing graphics functions.

Right click on the screen and goto properties, select the setup tab then advanced options, in some models there's an option to change the ammount of memory used by the video chipset.

I agree with nltech, there is a spot in the BIOS to change the settings of "shared memory or onboard video memory" Its usually one of those. I have not seen a motherboard with 128MB onboard, but mine has 64 but it is disabled. I like the Nvidia card better than onboard. If you want to stay with the onboard though, you need to go into the BIOS and change the settings window will usually only let you setup 64MB of video RAM but only will us it when you game leaving it at like 10MB-15MB when its booting up. I have mine changed in the BIOS to disabled but you can change it I guess up to the 128MB. Give it a try but its the only way you can get it set like that permanently.

Useing 128 all of the time is not really necessary, it automatically allows the maximum supported by the program, more than the maximum is not necessary because it can only use the maximum amount.

Just out of curiousty, what exactly is it you are trying to achieve by doing this ?

correction, programs which don't use 3d acceleration, like internet and office applications, software development environments, photoshop and some games, need 'no' graphics memory at all. just the memory which is already located for the display, 4 - 8 mb or something.
