Gateway dx4200-09 bios question

Hi Guys,


I am using Brainsuck's Gateway-RS780-7B3P081G-ACER_2.1-OEM I D ACRSYS. It works. I have been using AMIBCP_V3.37 to make additional changes to access additional aspects of the bios, but have run into a problem.

In the Advanced Chipset Features / AMD 780 Configuration / Internal Graphics Mode, I have the Access / Use I have User, Failsafe I have UMA and Opitmal I have UMA. Under UMA Frame Buffer Size, I have Access / Use I have User, Failsafe 00 and Optimal I have 00.

Changing UMA Frame Buffer Size under Failsafe and Optimal from 00 to anything from 01 to 07. I flash the bios and When I start it up and entering the bios, I go to Advanced Chipset Features / AMD 780 Configuration / UMA Frame Buffer Size The choices never change. The choices are Auto, 64 MB, 128mb, 256mb, and 512mb.

The choices I am trying to add to the bios is 1024mb and 2048mb.

What I am I doing wrong?
