VGA modes. With 2 MB of SGRAM standard, the system supports special
Cirrus Logic extended modes. Table 40 and Table 41 list the standard and
extended modes that this implementation supports, including the number of
colors and palette size (e.g., 16 colors out of 256 K colors), resolution, pixel
frequency, and scan frequencies.
