The CueCat sends Alt+F10 before sending data. Maybe something (X, window
manager etc.) gets confused by a simulated Alt+F10 keypress.

The registers to change are documented in the datasheet of the specific
chipset by Intel. You'll have to look for the PAM registers (at least
that's what they're called for i8xx-chipsets).

The Windows XP driver doesn't care about the BIOS but bypasses it. X on
the other hand needs the BIOS to set the resolution because the
information on how to do that without the BIOS is not publicly available.

had this once with an embedded system which was only configured for a

video modes known to the BIOS can be set.
For the i855-chipset there is a utility called 855resolution to add
custom video modes to the video BIOS. Maybe it'll work with i865, too:

"undefine" the 1024x768 mode and redefine it later so I think it should
work on a 500m, too.
I put a link on the 855patch page so maybe there will be some more
testers soon.

in that list that are supposed to point to the resolution data are
pointing to nonsensical values instead. I couldn't figure out how to fix

Maybe someone else with the appropriate hardware could try.

But you have to make this area writable first. Documentation for that
can be found in the 855GM datasheet from Intel. And probably you'll have
to initialize the new BIOS by calling 0xC0003 in real mode. This call
crashed for me so I had to patch some bytes of the BIOS image.

Sure, in the worst case. As I wrote, the BIOS not configured properly.

Hallo,
an interesting thing to know is whether there are i855GM notebooks by
other companies using the same BIOS build (3066) and if these show the
same problem.

Hi,
I just forgot to say, that BIOS build 3197 is newer than the one
installed on the new Dell machines (build 3066). So if it was an error
by Intel they already fixed it.

that that's a much dirtier solution to the problem than the patched
driver but nonetheless I think it might be useful for people who want to
use the precompiled XFree86 that came with their distribution.

Hi,
Thank you Alain for sorting out this problem and Alan for commiting a patch.
Would it be possible to offer binaries or a small, easy to build source
package? I think many of the users affected by that problem can't build
or don't want to build the whole XFree86 from source.

Hi,
as developer of 855patch I get a lot of feedback from people using
XFree86 on computers with i855GM graphics.
It seems like new notebooks by Dell feature a new video BIOS from Intel
(iirc Build 3066) which finally implements the int 0x10 0x5f11 function
to set the amount of video RAM and thus
my 855patch and its function was verified by some 845GL users
(I don't have a notebook using that chipset).
