Description
This function reads the hardware color palette information from the hardware, and is only valid in 8-bpp and lower color index modes. Color palette information is returns from this function in an array of GA_palette structures. Each value in the GA_palette structure is 8-bits wide, with a range of 0 to 255. Note that this is different to the standard VGA palette programming routines, which normally take 6-bit wide values. Internally the driver will convert the 8-bit palette values to 6-bits if this is what the underlying hardware supports.
