Custom Intel 945GM Drivers for Lilliput EBY701 - Native 800x480

AvWuff · 05-10-2009, 01:26 AM

Hi guys,

After many hours of futzing around, I finally got my Lilliput EBY-701 to work perfectly with 800x480. I've modified these newest Intel drivers for the 945GM chipset to add that resolution as an option.

Hope it works for you, Enjoy!

Does it support Lilliput 8" (889GL-80NP/C/T) LCD ?

No idea. I made it for what I have :-)

I run the TVWsetup.exe, but it said that my system can not meet the mininum requirement. (WINXP SP3).

Oh, don't run the set up -- simply unzip the drivers, then go to your Control Panel, System, Device Manager, and select your 945GM card from the "Display Adapters" list. Go to properties, Driver, click Update Driver. Then click to specify your own driver, click "Have Disk" and point it at the folder where you've unzipped the driver. Select the driver that comes up and let it install, and you'll be all set!

Oh, thanks for your post. Could you pls point out what modification you made in the driver? since My chipset is Intel 945GME Express chipset.

Sure, all I did is download the latest driver for the 945GM from Intel's site. Then I unzipped them.

I opened up the igxp32.inf file in the Graphics folder with Notepad, and made the following changes:

Under the section [NonEDIDMode_AddSwSettings],
I changed "TotalDTDCount" from 0 to 1.

Then, below that , I deleted the line that starts with HKR,, DTD_1 and replaced it with this line:

Code:

HKR,, DTD_1,%REG_BINARY%, 82,0C,20,E8,30,E0,50,10,28,50,D3,0C,00,00,00,00,00,1E,37,01		;800x480

This is essentially the DTD that I found works with the EBY-701 and the 945GM. They might not work on other adapters.

Once I finished that, I saved the file and then followed the steps to make Windows use that driver for my adapter.

By the way, I found the steps for how to make my own drivers with the Intel chipsets from this page:

Good luck!

where did you find that DTD code? ( tring to repicate with a different chip(ati) )

Well, I started with some other drivers I had found years ago that provided 800x480 on the Xenarc, but they never worked properly. I tried them again on the Lilliput when I got it, and it sorta worked -- the picture was there, it was the right width, but it was squashed with big black bars across the top and bottom.

So, I said, "Hmm, it looks like I've almost got it, I just need to change the scan frequency and adjust the front and back porch on the vertical scan." So I fiddled with the numbers until it worked perfectly.

I used DTD Calculator to actually generate that DTD, by inputting the numbers.

Good luck,

What tool you were using to see if the setting is right? Powerstrip or just re-install the driver on each retry?

Reinstall each try. Luckily, my guesses were pretty close and it actually worked perfectly on my second try :-)

I think it is to modify the windows registry. If so, both DTD caculator and make a .reg file will work too, right?

I suppose, but DTD calculator's "apply" option didn't work for me. That's why I reinstalled the driver each time.

After many retries, I got it finally

The dirver is just yours at first post, the point is I must delete the device before install the driver for it, or the LCD just keep black or said "NOT SUPPORT". Once the driver install sucessfully, the display was 800x480 but not point to point with the LCD. I use the LCD auto adjust function to make it point to point.

Now the display was perfect, but has a problem. When I unplug and reconnect the VGA harness, the display will be incorrect. Need reboot windows to solve it. Forunately, there will be a little chance to unplug the VGA during windows running.
