Found this on comp.sys.mac.hardware.video
The best way to determine the amount is to see what resolution/color
combinations are available in the Monitors control panel. Check the
color depths available at various resolutions.
Look at the highest resolutions permitted, and the color depths that
are
valid at each resolution. Compare this with the charts in the spec
sheets. (Note that the 4400/160's video capabilities are not exactly
the same as the 4400/200's)
If you have 1280x1024 resolution, then you've at least got 2M. If
that
resolution is supported at 8-bit depth (256 colors), then you have 2M.
If it's supported at 16-bit depth, then you have 4M.
If your monitor doesn't support 1280x1024, look at the depths at
1024x768 res. If the maximum depth is 8-bit, then you have 1M. If
it's
16-bit, you have 2M. If it's 24-bit, you have 4M
If your monitor doesn't support 1024x768, then you don't need 4M,
since
you'll be able to get 24-bit color at 800x600 with only 2M of VRAM.
If
800x600 has a maximum depth of 16-bit color, then you have 1M of VRAM.
Hope this helps,
Ben.
