Yeah, thats pretty much the 'way of PCI', so I was surprized not to see the IRQ line assigned from the x86 host-side. > Umm...

Oh, perhaps the comment was that you had used the board then :) > I'd have to check the u-boot source for PrPMC support, as I > haven't run u-boot on it. No sweat, if I want to put U-Boot on it, then I'll just have to port it :) Since the Artesyn bootloader can tftp etc, I'll figure out first how to get Linux booted. I just booted up the second board, and it did not get an IRQ either. I'll dig into the CPC700 manual, its likely a boot-time enable. Thanks for the feedback! Dave
