The DAC LUT test failed.
An error occurred while testing the DAC LookUp Table. The problem should
be visible on the top color bar of any 8 bpp mode.
A ROM checksum error occurred.
An error was detected in the ROM.
The draw sequence failed.
An error occurred in the draw engine. If the error is intermittent, there may

immediately apparent.
Video mode tables
This section describes the video mode specifications for ATI video drivers
using DRAM.
When discussing color depth, 8 bits per pixel (8 bpp) is the same as 256
colors. Therefore, the relation between bpp and colors is as follows:
Bits per pixel Number of colors
8 256
16 65,000
24 16,700,000
32* 16,700,000
*32 is 24 bpp color data processed using a 32 bpp data format.
The ATI video drivers also support 15 bpp (32,000 colors). Any resolution and
refresh settings that support 16 bpp will support 15 bpp.
