@publius This one dual boots XP too, I can't get some things to work properly in Linux on it. Wireless is a bit flaky, but looks like I've found a workaround for it:

I also have a PCMCIA GPRS-modem in it and I can't get it to work, the serial port just gives me some garbage. It works perfectly in Windows. Now I think, maybe it's the same problem — IRQ conflict 🤔
