[PLUG] kernel and bios and pnp

[Jeff Abrahamson <jeff@purple.com>]

Here's a bit of oddness that I don't understand.  I boot my kernel
with the nobiospnp option, and yet it still seems to pay attention to
the bios pnp stuff:

    jeff@astra:~ $ dmesg | grep pnp
    Kernel command line: auto BOOT_IMAGE=Linuxn ro root=301 noapic nobiospnp acpi=no
    PnPBIOS: You may need to reboot with the "nobiospnp" option to operate stably
    isapnp: Scanning for PnP cards...
    isapnp: No Plug & Play device found
    jeff@astra:~ $

Any idea what is meant here?  The problem for me is that my machine is
(still) not stable, although it's usable if I lower my standards.

In fact, the detailed output (other than the first line) is this:

    Linux Plug and Play Support v0.97 (c) Adam Belay
    PnPBIOS: Scanning system for PnP BIOS support...
    PnPBIOS: Found PnP BIOS installation structure at 0xc00f57b0
    PnPBIOS: PnP BIOS version 1.0, entry 0xf0000:0x656a, dseg 0xf0000
    PNPBIOS fault.. attempting recovery.
    PnPBIOS: Warning! Your PnP BIOS caused a fatal error. Attempting to continue
    PnPBIOS: You may need to reboot with the "nobiospnp" option to operate stably
    PnPBIOS: Check with your vendor for an updated BIOS
    PnPBIOS: get_dev_node: unexpected status 0x28
    PnPBIOS: 6 nodes reported by PnP BIOS; 6 recorded by driver
