Christian Zietz writes: Hi, as I already pointed out some of the users affected by the problem don't want to or aren't able to build XFree86 out of the CVS sources. So I wrote a small hack which wraps around int 0x10 and prevents the function in question (ax=0x5f64, bx=0x0300) from being called. I'm aware 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. Download URL for 855wrap: http://www.chzsoft.com.ar/855wrap.tar.gz I think it would be worthwhile to investigate the origin or the problem and report it to Intel to fix it in the BIOS - in case they have broken something. It looks like an endless loop to me. Since the problem appears both to happen inside the emulator and vm86 mode it points to the BIOS however we cannot say for sure. One may want to try to set up registers and execute this command from 'debug' inside DOS to see if this ends up in an endless loop also.

It runs latest BIOS (v2) as posted by Dell on their web site. The video chipset is Intel 82852/855GM. I installed XFree86 4.4 RC3 with RH 9 kernel 2.4.20-30.9 (although I believe that the same problem occurs with XF86 4.3, but I didn't investigate in detail before upgrading). The monitor is XGA, capable of 1024x768 at 60 Hz. The symptoms are following; * 892 kB of video memory are reported by BIOS * vesa driver takes that amount and can run 1024x768x8 * i810 driver negotiates with BIOS for extra memory (the actual amount seems to depend on video modes specified in XF86Config, anywhere from 8-32 MB) * i810 driver freezes with green screen and the last line of log is; (II) I810(0): 2 display pipes available. Soft reboot seems like the only way to regain the control of console (ALT-F1, etc. doesn't work, although keyboard seems responsive) By changing video modes I tried to convince i810 driver not to request extra video memory, but even for 640x400x8 (4 and 1 bit depth seem not to be supported by i810) it tries to allocate at least 8 MB. I'm attaching the logs (successful vesa and frozen i810) and config file (where I onlt toggle between driver in question).

Egbert.
I've got this problem with the new Dell 510m model : with the normal i810
driver, we've got only a total green screen.
The problem comes from the call to INT 10h, 0x5f64 in the
GetDisplayInfo() function. It never returns.
As this function is only informative, I commented out its call in
I830DetectDisplayDevice() (XFree86 4.3.0.1) :
...
static Bool
I830DetectDisplayDevice(ScrnInfoPtr pScrn)
{
I830Ptr pI830 = I830PTR(pScrn);
int pipe, n;
DisplayType i;
#if 0
for (i = 0; i NumKnownDisplayTypes; i++) {
if (GetDisplayInfo(pScrn, 1 i, pI830-displayAttached[i],
pI830-displayPresent[i],
pI830-displaySize[i].x2,
pI830-displaySize[i].y2)) {
xf86DrvMsg(pScrn-scrnIndex, X_INFO,
Display Info: %s: attached: %s, present: %s, size:

}
}
#endif
pI830-configuredDevices = GetDisplayDevices(pScrn);
if (pI830-configuredDevices == -1) {
xf86DrvMsg(pScrn-scrnIndex, X_INFO,
Failed to detect active display devices\n);
return FALSE;
}
...
Now all is working fine (except the fact that the 1500x1040 resolution
is still not reconized by the bios).
I hope this help.
Regards
PS : not more need to use 855Patch with this bios.

That's good to know. This call to GetDisplayInfo isn't strictly needed,
but it's useful information to find out about the attached displays.
It's probably wise if we make this an option in the driver and turn
it off by default.
