Hi, i've the same problem with windows 7 x64
with 1.13 bios, i can see only 2.75GB at startup, while with bios 1.05 to 1.10 bios i've about 4GB at startup
i have 2x2gb=4gb
In windows, if you mount the SIS driver, you obtain 2.75GB (3GB-256MB)
note: if windows 7 x64 installs without sis vga driver see 3.5GB. as vga driver install back to 2.75gb
if windows 7 x64
Anyone have a solution ?
