Re: Intel embedded graphics driver

I have successfully used the IEGD. Maybe info below will be useful.
In the INF file check the settings..
The following settings (displayconfig, portorder) in inf will enable clone
mode, with lvds and crt.
Also might be useful to turn overlay off depending on the intended purpose
in clone mode.
[ssigd_SoftwareDeviceSettings_alm]
HKR, Config\1\General, DisplayConfig, %REG_DWORD%, 2
HKR, Config\1\General, PortOrder, %REG_SZ%, "5400"
HKR, Config\1\General, OverlayOff, %REG_DWORD%, 1

Please refer to the manual for info on parameter settings.
The FAQ on the intel website if also useful (specially for understand
overlay settings).

Yes I also looked at modifying the inf file but got all too hard for
me.

But watch out with the standard driver, I've found with some boards if
you boot with a VGA monitor not plugged in it disables this output.
When you next reboot (assuming you don't have ewfmgr enabled) it
remembers that the VGA monitor wasn't pluggged in and not enable the
VGA output.

I followed the same path as you, if I do find a solution I'll send keep
you posted.

Hi Robert
I just forgot that I tried the embedded driver and it behaved the same way
as your: work on VGA and not on LCD.
My download was IEGD_5_1_window.
I had problems with the included SLDs and had to modify .INF files so I
thought that was my problem and gave up.
According Userguide, display config should be set in the .INF file, I did it
following the exemples but my tests gave no success. Probably I forgot
something.
I got the full version .ZIP and made components from it, and these are
really working with both displays, so I forgot the embedded version.
Really it's big, but has more features. Perhaps many files are useless, to
reduce the footprint: this should be checked, but space is not my concern
now.

Sorry I made an typo, it's a 855GM not 845 that I'm having problems
with!

Hi Raffaele,

Yes I've got a LCD panel connected directly to the board via LVDS
interface.
Standard windows XP driver works fine, actually I got around the
problem by installing the standard Intel Graphics driver on my XPE
platform.

To reduce my footprint, I would ideally like to get Intel's embedded
graphics driver working.
I've used a couple of version of the Intel Embedded Graphics driver and
have the same problem, it always defaults to VGA and DVI output. Their
is no option to enable the LVDS output via the iegdgui utility

Hi Rob
what's connected to the LVDS port? I suppose a LCD panel. And you see
the
bios screens and the WIN splash screen, after that when the driver
starts,
this display is black?
Intel driver install 2 video devices, each one for each interface, so I
guess that no more than 2 devices may be connetted at the same time.
Config utility allows to have the same screen on both ( dual display
clone)
or a different image on each or to have only one device.
Have you tried to connect only 2 devices f.i- the LVDS screen and VGA?
If
LVDS works ok you should find it in the config utility.
Have you checked the full Intel Driver on your hardware with XP Pro?
It's
also available as a XPE component in xpefiles.com

Hi All,

Having little luck with the intel embedded graphics driver on the
845GM
chipset.
The embedded baord has several video outputs, LVDS, DVI and VGA.
But once the video driver loads during the video boot process, LVDS
output is disabled and will only output to DVI and VGA.
Have attempted to play with the Intel's configuration utilityIEGDGUI
utility, but the only two options I have are VGA and DVO-C. I can't
for
the life of me get LVDS output to come on. Which is what I need.

Have read Intels documentation of how to enable LVDS output, but this
went straight over my head.
Any help would be great!
