Broken - is it a broken bios (so I will ask HP for an update), or is it just how things works? ;) BTW, there are quite some resources mentioned at PNP init time, like this: pnp: 00:08: ioport range 0x680-0x6ff has been reserved pnp: 00:0c: ioport range 0x400-0x47f could not be reserved pnp: 00:0c: ioport range 0x680-0x6ff has been reserved pnp: 00:0c: ioport range 0x500-0x53f has been reserved pnp: 00:0c: ioport range 0x500-0x53f has been reserved pnp: 00:0c: ioport range 0x400-0x47f could not be reserved pnp: 00:0c: ioport range 0x295-0x296 has been reserved pnp: 00:0c: ioport range 0x3e0-0x3e7 has been reserved > I'd like to see how the PnP layer is interpreting this, and also what your > _CRS method is giving us. > > Could I see the output of: > > /sys/devices/pnp0/00:XX/resources > > and: > > /sys/bus/pnp/devices/00:XX/options > > where XX is the function number of your parport device... In one of your > earlier emails it was "08". Sure. With one exception: I can't find a machine where this is really "08" now. I think I grabbed all that info from our machine here at office (HPML150), but now it is reporting id 00:07, not 00:08 (maybe after we experimented with various modes of parallel port - ECP/EPP/Standard - in bios). Maybe it was from another machine (in a remote office) where I first tried to deal with the problem. I checked current dsdt - it's still the same as on the URL above. Here's all the stuff from /sys/bus/pnp/devices/*/{resources,options} on this machine (HPML150), devices 00:06 (serial port) and 00:07 (parallel port) are on top, after first load of parport_pc and 8250_pnp modules (for all other devices, options file is empty): 00:06 state = active io 0x3f8-0x3ff irq 4 irq 3,4,5,6,7,10,11,12 High-Edge Dependent: 01 -
