Greetings. I have an Alphastation 255 with two D-Link 530-TX+ cards and a Promise ATA-100 controller in the PCI slots, running 4.4-RELEASE. After looking through the archives and Google, I can't seem to figure out how to get the onboard DEC Ethernet controller (de) to initiate when the PCI slots are full, due to an IRQ conflict. At boot, whatever card happens to be in the third PCI slot snatches IRQ 5, which causes the init of de0 to fail. It seems that the firmware will always map the onboard ethernet to IRQ 5, assuming that other devices can be shared. I can't find any utility like iconfig or ewrk_config to remap the onboard ethernet IRQ, and I can't seem to get de0 to come up unless I leave that slot empty. I'm hoping that rebuilding the kernel and assigning de0 an IRQ explicitly will help, but I'm still hunting down weird 'link already exists' errors. Is there some nifty way to remap the IRQ of de0 I've missed without recompiling? Thanks.
