    Help... VIA EPIA EN12000 w/ 7" Lilliput LCD

    Surely this is a no-brainer for someone out there and no one else seems to have encountered it...

    I have an nLited XP Pro SP2 system running almost perfectly, except I have the Display Type in the BIOS set to CRT, since the LCD option causes the display to spill out beyond the bounds of the screen.

    The Auto Adjust option on the Lilliput causes it it jump around a little then revert to where it was. There is not enough scope within the manual adjustment to make it usable.

    If I don't install the Hyperion Pro 4n1 chipset driver, the display type remains as CRT and seems to work fine. If I install the driver, it detects the LCD and adjusts the BIOS accordingly, which I don't want. I guess the simple answer is don't install the driver right???

    There is also an option in the BIOS labelled Panel Type, which I think might be the key to this problem. The motherboard manual suggest that this refers to the native resolution of the display being used, but doesn't provide a guide or key, other than [Min = 0000, Max = 000F], which is a HEX entry.

    When I changed the value to 0000, the display was visible on the LCD, but was too small. I then tried 0005 which didn't display anything and required the CMOS battery to be pulled from the board (the BIOS reset jumper is too tricky to reach).

    I'm very surpised that a search here or on Google failed to shed any light on this, what am I doing wrong?

    Thanks in advance,
    HamR.

    I am currently fighting much the same problem: I believe that Windows XP is intermittently changing my BIOS setting from CRT to LCD, which I don't want, even though I am using a 7" Lilliput touchscreen. Once the BIOS is set to LCD, nothing displays after the Windows XP opening screen. I have no idea what is causing this problem. I have an e-main from VIA Tech Support: If connecting through the VGA connector, you do not need to set the panel type as that option is for LVDS daughterboard option. So, I believe, you should leave the BIOS set to CRT 0007.

    Amendment

    Contrary to my initial message, it is actually the VIA VGA driver causing the motherboard to change the Panel Type from CRT to LCD.

    I have noticed that when the driver is installed, it first installs the S3 Unichrome driver, then Windows recognises the Lilliput as a Plug n Play monitor and automatically installs the appropriate driver. It is when the monitor driver is install, not the video adapter driver that the display shows a "No VGA Signal" message.

    I can boot with VGA enabled (F8 on boot) and the screen shows 800x600 at 8-bit color, but any attempts to change resolution or color depth result in the monitor not receiving a VGA signal.

    Perhaps I'll connect to it with VNC (or similar) and see what's going on.

    HamR.

    Boot to safe mode, and change your monitor under Properties Panel to standard 800-600 display.
    Now Galileo is real. Muhahahahaha :p

    Thank you for the feedback.

    I have just plugged a CRT into the PC and discovered that the native resolution after the VGA driver is installed is 1024x768 at 32bit color. If I drop the resolution to 800x600 at 32bit color, the Lilliput will work again...

    At least until I reboot and the BIOS reverts the panel type to LCD. Any ideas on how I can keep the BIOS from changing the panel type from CRT to LCD?

    Okay, setting the Panel Type to CRT+LCD in the BIOS seems to kind of work. The POST settings don't display nicely, neither does the boot screen, but Windows itself seems fine.

    Since Suspend To RAM seems to work perfectly on the EN12000 the misalignment of the boot data can be over looked. I guess I could always try misaligned boot and BIOS images if it annoys me too much.

    Cheers,
    HamR.

    Hello there,

    Yes, really, CRT+LCD setting helps in such a situation. Thank you!
    But what about resolution 800x480 in XP? Have you achieved it? I installed last graphics driver for my EN mobo but without success. Now I just have common res: 640x480, 800x600, 1024x768 and etc. But 800x480 - no. Powerstrip doesn't help me too because display driver doesn't support custom resolutions.

    Best wishes.

    After years of installation, I finally have this problem after reformatting the carpc all over again, now with SP2. (before this it was simply XP SP1).

    I tried CRT+LCD in bios but I get the OVER RANGE notification.
