The docking station has a built in Ethernet card and I use an Ethernet and modem PCMCIA card. Problem: I seem to be out of IRQ's! I use FreeBSD 2.2.1 and PAO and this is "dmesg | egrep irq" edited a bit and adding some comments irq 1 sc0 at 0x60-0x6f on motherboard irq 2 (the programmable interrupt controller) irq 3 pcic: controller irq 4 sio0 at 0x3f8-0x3ff on isa irq 5 sb0 at 0x220 drq 1 on isa (built in SB Pro comp. ESS ES1688) irq 6 fdc0 at 0x3f0-0x3f7 drq 2 on isa irq 7 lpt0 at 0x378-0x37f on isa irq 8 (CMOS/real time clock) irq 9 (free??) irq 10 ed0 at 0x300-0x31f on isa (ethernet in docking station) irq 11 (free) irq 12 psm0 at 0x60-0x64 on motherboard irq 13 (built in math processor) irq 14 wdc0 at 0x1f0-0x1f7 on isa irq 15 wdc1 at 0x170-0x177 on isa (in docking station) I can't disable PnP, there is no option in the BIOS setup, but this is also what Windows95 reports so I believe it is right. I haven' tried that the sound card work from FreeBSD yet (how do I do that?). Problem is, if I set 9 and 11 for PCMCIA card use in pccard.conf it works "almost". It slows down Ethernet 500 times or make the modem work unreliable. If I'm not docked IRQ 15 gets free and giving PCMCIA 11 and 15 is ok. So I suspect IRQ 9 isn't really free. Is there a way to make the PCMCIA cards share the same IRQ? How do I debug conflicts like this? Is there some commands that give information or test things? Recommended reading? I can't be the only one having IRQ problems ;-) I have tried zillions of combinations of settings in /sys/i386/conf rebuilding the kernel and in /etc/pccard.conf but haven't found the logic in this thing. /kgb
