Script to backup Win9x\ME drivers from a working install

I was playing around with an old 9x box and drivers are a pain.
The library here is great, but I wish there was an online driver library to AUTOMATICALLY find drivers.
Or at least some sort of pack that can be looked up from a fresh machine.

I didn't do that.
I did what I think might be the first bit required:
Getting the drivers from a working install into a workable structure including versioning (I used the driver date in YYYYMMDD) that maybe, just maybe, someone will figure out a way to make a more automated driver library.

The script does not intentionally modify any existing files or the registry.
There is no reason it should. Weird bugs happen though.

The coding style... uh... it works. COMMAND.COM is more limited than CMD 🙁
Frankly, it's pretty horrible what had to be done. command.com doesn't have: IF with ELSE, (proper code blocks), FOR in a very useful format, WHILE, and a bunch of other things.
Ever made a while loop with if and goto?
How about if/else with gotos?
It's not pretty. I'm honestly a bit surprised that I got it to work at all.

Dependencies:
reg.exe in the win98 resource kit: https://archive.org/details/mswin98rskt
gawk.exe available here: https://gnuwin32.sourceforge.net/packages/gawk.htm
MSVCP60.dll available here: https://www.dll-files.com/msvcp60.dll.html (I used V 6.0.8168.0 but others might work)
xset.exe available here: https://xset.tripod.com/

How it works:
Reads the registry and finds PCI devices in HKLM\enum\pci
Follows that trail to find details and the INF file that installed them
Attempts to find the INF in (windows directory)\inf and inf\other
Reads the INF looking for the names of the files required
Scans the windows directory for the listed files
Copies the inf and required files to (this folder)\Drivers with subdirectories for driver class, and the driver folder includes its date version
Updates a 'master list' (VenDevList.txt of ALL vendor and device ids listed in each INF with the path to the driver (I figure this would be the index file if anyone ever put it into an online database)

How to use:
Download attached script with dependencies OR
Copy the code below into notepad.
Save as a .bat (I used drvbak.bat)
Get the 3 dependencies into the same folder
Run it from... Well, I've only tested it on the C drive of a 98 box, so I'm going to say put it in a folder in the C drive somewhere. It might run from d: etc, but I don't know.

If you get out of environment errors, configure the dos window with more memory
I used initial environment 4096, EMS 8192, XMS 8192, DPMI 2048
In theory it will run from dos mode.

I'm curious:
1) if anyone cares
2) if anyone likes it
3) how awful you all think my code is. Some could be revised already, I know, but if it ain't broke...
4) how badly it's going to completely fuck up on someone else's machine

Oh.
Hmm.
I ran it from the command line
Best guess: it's starting in c:\windows and not finding the dependencies.

Nope. not that.
Forgot a dependency. Sorry!
Xset

https://xset.tripod.com/
Has to be in the same dir.
Then it should work

I've updated the zip and code.

I've had times I would have used this for sure. You land some old system, it's got a working 9x install. You want to start fresh, but that means you have to investigate all the bits and find the drivers online. Thanks for sharing - I'll give it a whirl next time I've got a suitable box on the desk.
