Hi,
I am using a HP Omnibook 6000 Notebook with the following graphic chipset:
ATI Technologies Inc Rage Mobility P/M AGP 2x (rev 64)
Without forcing a chipset in libvga.config vgatest uses the following
configuration:
Using RAGE driver, 8192KB. ChipID:35 MemType: 4
Rage: BIOS reports base frequency=59.000MHz Denominator= 64
svgalib 1.4.3
It seems like all video modes are not working properly with the Rage driver
so I forced using VESA, which is working very good with high video modes
(640x480x256 and higher) but these lower modes are not working:
1: 320x200, 16 colors (4 bitplanes)
2: 640x200, 16 colors (4 bitplanes)
3: 640x350, 16 colors (4 bitplanes)
4: 640x480, 16 colors (4 bitplanes)
5: 320x200, 256 colors (packed-pixel)
6: 320x240, 256 colors (Mode X)
7: 320x400, 256 colors (Mode X)
8: 360x480, 256 colors (Mode X)
9: 640x480, 2 colors (1 bitplane, monochrome)
32: 720x348, 2 colors (1 bitplane, monochrome)
These modes show garbage on the screen, colorful snow. I think that's what
you call "Out of sync"
Most of these modes are rarely used, but Mode 5 is important to me. Even with
forcing the "VGA" chipset this mode is not working. The same garbage on the
screen. It looks to me as it has something to do with the number of colors.
320x200 with 16 Bit or higher is working properly, but 256 colors and lower
are not working.
What can I do to get these low video modes (or at least Mode 5) working?
