I dont know about devconf ($ locate devconf produces empty output as well) but pciconf results are as follows: ahd0@pci2:6:0: class=0x010000 card=0x005e9005 chip=0x801d9005 rev=0x10 hdr=0x00 vendor = 'Adaptec Inc' device = 'AIC-7902B Ultra320 SCSI Controller' class = mass storage subclass = SCSI ahd1@pci2:6:1: class=0x010000 card=0x005e9005 chip=0x801d9005 rev=0x10 hdr=0x00 vendor = 'Adaptec Inc' device = 'AIC-7902B Ultra320 SCSI Controller' class = mass storage subclass = SCSI bge0@pci2:9:0: class=0x020000 card=0x164414e4 chip=0x164814e4 rev=0x03 hdr=0x00 vendor = 'Broadcom Corporation' device = 'BCM5704 NetXtreme Dual Gigabit Adapter' class = network subclass = ethernet bge1@pci2:9:1: class=0x020000 card=0x164414e4 chip=0x164814e4 rev=0x03 hdr=0x00 vendor = 'Broadcom Corporation' device = 'BCM5704 NetXtreme Dual Gigabit Adapter' class = network subclass = ethernet The server runs i386 version of FreeBSD (5.3-RELEASE-p5) since I experienced some problems building ports on amd64 version. > In many cases there are not other IRQs available to route, due to poor > BIOS programming, ccorners cut in the physical board layout, etc. I think this is the case :/ The BIOS assigned all those devices IRQ10 and there is no way to change the settings...
