Black screen when using WAB driver under Windows 3.1 with MELCO WSN-A4F

[frank-deng]

When entered the Windows 3.1 desktop, only the wallpaper and some icons in the Program Manager displays well, with some garbled displays on the top of the screen.

Do you use Win98's driver?

If you can read Japanese, setup guide in follow page. https://sites.google.com/site/np21win/setup/win31

Thanks! I used the original Windows 3.1 PEGC driver.

Also, is it possible to port MELCO WAB high resolution display support to SDL and X11 version.of NP2?

[AZO234]

I'm trying to port WAB to SDL and X11 version. I'll do it carefully and slowly.

[AZO234]

I added WAB implementation. Please try to use it!

[frank-deng]

Thanks! But I failed to start Windows 3.1 with error like this: I used the video driver downloaded from here.

[AZO234]

Did you apply pseudo driver(OEMSETUP.INF) before install WSN's driver?

I enabled Window Acclerator option in X11 version of NP2, and used the downloaded WSN driver. Now it does not give error message, but after entering windows 3.1, it gave me white screen. "MELCO WAB-S" option was used.

[AZO234]

Probably you should use "MELCO WSN-A4F".

[frank-deng]

Thanks! I updated the code and used "MELCO WSN-A4F" at Window Acclerator option. After I started Windows 3.1 with the downloaded WSN driver, it gave me a black screen. Also, if I display JPG images using JPGVCLH then entering Windows 3.1, it will give me the image displayed previously.

[AZO234]

I'm pleased that it works. You did it! I'm sorry for my poor guidance.

On X11 version of NP2, I used "MELCO WSN-A4F" at Window Acclerator option, then use the driver for Windows 3.1 from here. After I started Windows 3.1, it gives me a black screen. Also, if I display JPG images using JPGVCLH then entering Windows 3.1, it still gives me the image displayed previously. With console log messages like this:

Thanks! I replaced A:\WINDOWS\SYSTEM\EGCN4.DRV and A:\WINDOWS\SYSTEM\PEGCV8.DRV with the one from Windows 98, and now 640x480x256 under Windows 3.1 works well. May I add it to README.md?

[AZO234]

Oh, sure! I hope to your experience make other windows user better.
