I don't think so. But I might be able to fiddle with it in the boot-up userconfig... I'll try that. The big problem is that the 'pnp' userconfig command is gone. So I don't know on which irq the modem is setup. In 2.x and 3.x, I could setup the irq and port settings and then setup the sio2 probe appropriatly, but now, I'm out of resources... > The only other thing is: It's not a bloody Winmodem is it? :) It shouldn't. I mean, I used it as a non-winmodem for a good while on FBSD and it worked, that should be proof enough.

One time, it started "detecting new hardware" but detected that stuff like... er... "Main board" and "Central processing Unit" were _removed_. Ah! It removed all the drivers for all the devices I had on my machine. Quite funny. Reinstall. :) > > Latest dmesg (25th build! :): > > You are now appointed as our resident kernel building expert :) yay! I'll try to probe different IRQs from userconfig and see what it gives... A.
