Has anyone of you configured PLIP on a stock kernel Red Hat
6.0 system?  I would appreciate any information that will help me
avoid re-reading myriad HOWTOs and source code (and probably still
failing).

        linuxconf is willing to try, but fails.  I've tried a few
things from the root shell prompt after skimming the PLIP mini HOWTO
without success.

        I presume that it may be that I have to build a kernel
different from the stock kernel, but I'm not sure.  (Does anybody know
a short cut for determining which configuration options Red Hat used
for building a kernel, or does anybody have a favorite working set of
such?  The more recent - later than RH5.2 - kernels that I've built
have always seemed slightly unsatisfactory.)

        I need to insmod parport before plip of there are unsatisfied
symbol references.  But then insmod plip complains:

    /lib/modules/.../plip.o: init_module: Device or resource busy

and the following get appended to dmesg:

    parport0: PC-style at 0x378 [SPP,PS/2]

(I'll worry about setting EPP and/or ECP later: it didn't help on the
other machine that I'm also trying this on)

    parport0: no IEEE-1284 device present.
    plip: parport0 has no IRQ.

(!! IRQ 7 is at least available, according to /proc/interrupts)

    plip: no devices registered

The lack of an IRQ seems like a fine reason that no devices were
registered, and the fact that no devices were registered seems like a
fine reason that "ifup plip0" reports:

    SIOCSIFADDR: No such device
    plip0: unknown interface: No such device
    SIOCSIFDSTADDR: No such device
    plip0: unknown interface: No such device
    netmask: Host name lookup failure

and dmesg gets 4 more instances of:

    plip: parport0 has no IRQ.
    plip: no devices registered

        In light of the above, the contents of the "files" in
/proc/parport/0 are unsurprising ("irq" contaings "none", "hardware"
includes "irq: none", and "devices" is empty).  On the other machine,
where I have in the BIOS peripheral setup section set EPP and
confirmed that IRQ is 7, the results are similar (except for the
addition of EPP to the port mode lists).

        lp is not mentioned in /proc/devices, and being sure not to
start lpd in the runlevel doesn't help.

                                                        Bill
