v = Virtual Screen
* = Other sync rates available with VGAMODE.EXE in C:\CPQDOS
c = Other sync rates available with CLMODE.EXE or WINMODE.EXE in C:\WINDOWS\WGAUTIL
d = External monitor must support 800 x 600. The 640 x 480 mode is centered in an 800 x 600 display here will be a border around the 640 x 480 diskplay in simultaneous mode. This is because the internal display panel still has to run at 800 x 600 sync rate
