On my ThinkPad 600, The ThinkPad PnP BIOS configures all PnP devices at boot time. If I load the isa-pnp.o driver it never detects any ISA PnP devices: it says "isapnp: No Plug & Play device found". This is unfortunate, because it means that device drivers can't find out from isa-pnp where the devices are. David Hinds's pcmcia-cs package contains driver code that interfaces with the PnP BIOS. With it, one can list the resource usage of ISA PnP devices (serial and parallel ports, sound chip, etc.) and set them, using the "lspnp" and "setpnp" commands. Would it not be useful if the isa-pnp driver would fall back to utilizing the PnP BIOS (if possible) in order to read and change ISA PnP device configurations when it can't do this itself? If so, could this perhaps be done by bringing the Hinds PnP BIOS driver into the kernel and interfacing isa-pnp to it?
