dont have the PC so far that Windows 98 is up, so I used chkcpu. but it essentially just reads whatever is set up in bios it seems. I am currently still fighting with an issue, that it keeps telling my that the battery is low, which it is not. And so it forgot the cpu again. I kept that first report with the "wrong CPU" in. I then changed it in bios to the 350mhz cpu and ran it again.
Here is the complete log:

So from that it seems like it indeed is a K6-2 if it is trustworthy
