Sometime ago i wanted generic SVGA/VESA driver (like in XP) to include onto my 98 rescue CD.

I've found generic SVGA driver for Windows 3.11 circulating in net (SVGA.EXE, you can find it here for example).
But it refused to work (even in 3.1 on 486)

But recently i've found a cool patch which adds VESA compliant video card support to this driver.

And now you have 1024x768x256 instead of 640x480x16. I think it is much better!
MDGx may advise this driver and patch somewhere in his useful tips.

I've created a zip with required files and nothing unnecessary.
You must merge system.cb included into this zip with yours in \windows (if you have one) and copy other files into \windows\system.

After that, in safe mode, you will get maximum resolution. You can reduce "resolution=" in system.cb
I haven't tried it enough - it does not work under VMWare :no: (but nothing bad must happen, just error message and VGA driver loads)

Just tried it, merged the entried with my system.db as indicated. Also extracted the neccessary files to my system folder.

... booted into safemode to test. The patch seems to be a dud. I still had the generic 640x480 resolution and 16 colors. :unsure:

It works for me - just 60 Hz is not very pleasant vertical frequency.

I have ATI Xpert/2000 Pro video card with ATI Rage128 Pro graphics accelerator.

There is written in the file accompanying the patch:

SVGAPTCH will patch svga256.drv to make it VESA compliant. Svga256.drv is a 256 color video driver included in WfWG 3.11 with support for special graphics chipsets only. (enables Hi_res 256 color for ATI Rage 128 AIW AGP adapter for Wins 3.1)


Maybe really just ATI Rage128 is supported?

Is there any utility that lists all available VESA modes?

This driver is working fine on a fresh Windows 98 install. I couldn't do much of a test, since my USB-mouse doesn't work in safe-mode. I'm just a bit lazy when it comes to attaching PS/2 convertor-stuff.

I made some screenshots:

As you see, driver properly reads the Setup.bmp image.

1024x768 at 256 colors. Better than nothing.

And it's not very useful at all. It's just a basic SVGA driver for Safe-mode usage.

Modern videocard use drivers that also support 3D Hardware Acceleration :)

It's useful if you need to go to safe mode and hate to jockey around your icons after safemodes 640x480 throws them all out of kilter....since I play/test a lot of sw, it happens on occasion.

At least now, the icons don'tr move around....but it was not pleasant to view, either!
