get Everest Home Edition from Here ..second Vram is the On Board Ram on the AGP card ...plus 64 MB Shared emans as told earlier ..its borrowed from ur RAM ..so even if u think u have 8+64=72MB Vram but ur game is gonna Detect the Original entry only..so my guess is u must b having 8MB dedicated Ram..please use the link above to d/l everest and chk ur system ....
There r no Seprate drivers for ur VRam ...your AGP Drivers are ur Vram drivers..so keep them up to date...
