I'm having a problem with an old computer(s), Compaq Deskpro EN (small form factor). It's based on 810/815 chipset. Graphics chipset is intel 815. Frame buffer size is very small (current size is 1024kB) and it makes a problem for me. Is there any way to change (by some editing software) frame buffer size, or to unlock/unhide frame buffer size change option in BIOS?
I've used newest BIOS, but there is no option that I need.
I'll be really gratefull for help (if not possible - i'm stuck with useless junk... a lot of junk ).
