VGA problem??

[Guest]

I am new on XPe. I am working on the WinSystem EBC-855 board, boot from
CompactFlash which is Secondary Master. No floppy, CD-Rom, HD plugged in.

I leave the default Target Device settings from WinSystem as "Multi(0)
disk(0) rdsik(0)partition(1)" and other settings, only change the Boot
partition size from 975MB to 470MB( since I am using 512MB CompactFlash), and
the EWF settings->EWF partition size in Kbytes(481280KB==470MB), and build
the image.

During the First Boot, I can see on the display(CRT monitor) that all the
components installation and registration, then system reboot, display shows
"loading XP.." , my problem is, after that, the display only shows a
floating window with message 'Sync. out of range', if I change to another
Monitor, still show me ' no signal'.

I have Winsystem SBC component and WinSystem-Intel82855-Graphics Controller
component included.

Any component or configuration I missed?

P.S.

I am not positve that the system is still running or not , what I can see
from my power supply that the current still keep changing, and the keyboard
Cap LEd can be turned on and off, and also, after about 10minutes, the
display turn to completely black(looks like system idel mode) , if I hit
'Enter' key on keyboard, the floating window with message 'Sync: out of
range' comes back.

Any suggestion will be highly appreciated.

Charles,

Sounds like you are having display driver issue. What settings you set in TD for the display component you created? Make sure you
don't set the frequency too high.

Btw, what EWF mode do you use? If it is EWF RAM Reg (which is often the best choice for CF boot systems), then EWF partition size is
TD can be safely ignored - it won't impact anything at run time.

Also, if you want to know more about what's going on with your image. Check \windows\FBALog.txt on the target boot storage (you can
always copy and explore the file offline). Then you should see if and where it is failing. Perhaps, you may even be able to notice
display settings failures.

Charles,

I have some experiences with an Intel 855GME chipset based board and
XPe. As I read on the website of WinSystems, the EBC-855 board supports
simultaneous CRT and LVDS flat panel. The question is which output is
handled as primary display output. In your case it seems as if the LVDS
output is handled as the primary output. Your BIOS is configured to show
everything on both outputs but not your XPe respectively the Intel video
driver. So in the moment the computer leaves the textmode and XPe
switches it into graphic mode there is no output no more.
There are two possible solutions:

1. Try to connect an LCD display at the LVDS output.

2. Configure the Intel video driver with Twin or "Dual Display Clone
Mode" how Intel it calls.

I have the "Intel 828252/82855 GM/GME Graphics Controller" on my board
using the driver Version 14.19.50

Good luck and best regards
Dirk

Thank you Dirk and KM!

I set the Frequency to 60Hz, and the EWF is RAM mode.

Dirk, how to Configure the Intel video driver with Twin or "Dual Display
Clone
Mode"?? I don't see the configuration in BIOS , neither in the driver
settings.

Thanks again.

Charles,

my Board has a Phoenix - AwardBIOS and the display option calls "Boot
Display" and is settled in the "Advanced Chipset Features" section. There you
can choose CRT, LFP or both CRT+LFP. But I don't think that's the problem,
because you can see BIOS output while booting - right?
The problem with the configuration of the Twin or "Dual Display Clone Mode"
is, that you need two connected displays. I think that's the wrong path. I
only have had the idea that windows switches to another output. Try another
thing. While the PC is booting press the F8 function key to get the "Windows
Advanced Options Menu". Choose "Enable VGA Mode" from the menu. XPe will
start in standard VGA mode. You shouldn't have any problems with the video
mode. If the problem further exists, my theory of the output switch is very
likely. In this case contact WinSystems and ask them which video output you
should use. Maybe I bark up the wrong tree and you have a total different
problem. I have no other ideas in the moment.

Best regards
Dirk
