Describe the bug

I followed the procedure to install the extended 800x600 video mode on Win 2.x. I tried Windows 2.11/286 and 2.03.

There are basically two bugs.

1. The installation disk say sthat a multisync monitor is not present, but this error can be ignored.
   then the setup disk install the driver on the setup disk and start the Windows installer.

2. Windows freezes on the startup screen

The startup screen says ATI VGA Wonder, not EGA, but since this card uses the same 18800 chipset, it may not be an error, and the setup driver, disk seems to be genuine.

Procedure:

The EDRIVER.EXE file must be executed from dos prompt.

Note: In DOS 5.0 and latter SETVER.EXE must be loaded in config.sys. (it uses the win200.bin entry). The disk must be in drive A. Can't install from B drive.

Driver disks:

ATI EGA 800+ Drivers.zip

PD: I also found the drivers for 800, not the 800+. It has drivers for lower resolutions, like 720x410 and 800x560. But the files must be replaced manually as indicated in the readme file.
