Boot Option Question

When I boot my suse 8.1 OS the boot options include the drive info and a "vga=788" parameter. When I leave the vga=788 statement in X fails to start - I get a dull glowing screen - which is nice enough, but doesn't allow for a lot of interaction. I have stumbled onto the fact that removing the vga=788 parameter completely seems to allow X to work as billed. So my question: "What is this vga=788 specifying and how can I remove it or correct it so it works properly?" Regards, Hagen Finley
