This is for SiS 5598 onboard display adapter, win95. (perhaps win98 also)
The zip file includes 4 EXE files.
First launch the three files
597113-3.exe 597113-4.exe and
Then run setup.
After that your computer should recognize the adapter.
Now, if you have problems, and you get a blue screen each time you try to improve your display settings to be higher than 16 colors and 640X480, then this is the problem I had.
Put the 4th file called 597v113.exe somewhere in your hard drive. (Best in c \).
Add to Autoexec.bat a call for this file.
That's sould work.
