I recognize that message. I'm running 1.3 on my home machine, a
486DX2-66. I have an ISA 3Com 3C509 at IRQ11 and a VLB multi-I/O adapter
(IDE, floppy, serial, parallel). Strangely enough, the only settings for
the parallel port are "LPT2", "LPT3" and "DISABLED". I've set it to
"LPT2". The IRQ is also configurable, I can't remember all the options
but I set it to IRQ7. There's only one other card in the machine, a
SoundBlaster at IRQ5.

I can't really find any hardware conflicts, but NetBSD has always
complained about lpt0 being out of paper.

When the 3Com is ifconfig'ed at boot it hangs for a little while, prints
an "out of paper" message and continues.

I can also remember sysinst complaining about stray interrupts when I
configured the network in order to install via NFS.

Anyway, the 3Com card works, I've never had any problems with it.
Haven't tested the parallel port as I've got nothing to connect it to.

Here's the dmesg output from my machine (see especially the last line):

My PPRO machine at work (also running 1.3) has an LPT port on the
motherboard and a PCI 3C900 at IRQ9. lpt0 on this machine probes at
exactly the same address and IRQ:


lpt0 at isa0 port 0x378-0x37b irq 7


This machine never complains about lpt0 being out of paper.
