NSSI is a DOS based utility that allow you to view what hardware is actually in your box. Generally NSSI can tell you what is what 99% of the time.

To use NSSI simply unzip the file at the bottom here or copy the contents of the NSSI folder to a floppy disk. Then boot up in dos insert the disk and run NSSi. Once the program has actually loaded simply hit the run button and wait until it gives you its results which will include your BIOs string.

Once you know what you got it it is very simple to find the correct drivers for those parts.

NSSI Version 0.54.4 this is the latest version that as yet i have yet to test. This can also be found in the utilities folder.
