My Dell Lattitude needs this (or the PCMCIA NE2000 winds up sharing IRQ7 with

Unfortunately I installed SuSE Linux on it last weekend because I want IrDA
support.  Last night I just about got ppp over IrDA working with my Siemens S25
mobile phone.  It's a bit lumpy for telnet use though (round-trip time for ping is
~900 msec), although it's just about usable provided you don't look at the
screen while you're typing.  Reminds me of the days when I used to manage a
cluster of 2 VAX 11/780's with ~60 logged-on users each.  :-)

And the Linux install did manage to configure the PCMCIA NE2000 card
automatically BTW.  The laptop has no CDROM, so when I was installing
NetBSD I had to use the 2-disk install set with DDB so I could set
PCIC_ISA_INTR_ALLOC_MASK and install over ethernet.

Any chance you could put an install floppy image somewhere I could get at it?
That should be enough to boot up and check I can access the NE2000, and in fact
might be an easier way for most people to test it.
