Thanks Todd, you've been a big help so far.

That's great advice. I did a little digging and found that the CF
based wireless ethernet card still draws 250ma, so those are of no
gain. But I did find a few of those LP-E CF cards. I may end up with
But for now, a friend of mine lent me this card:
ep0 at pcmcia1 function 0pcic0: port 0x14000410-0x1400041f
: 3Com 3c589 10Mbps Ethernet
ep0: address 00:10:4b:de:7c:75, 8KB byte-wide FIFO, 5:3 Rx:Tx split
ep0: 10baseT, 10base5, 10base2 (default 10baseT)
This is a 3Com 3C589D-TP. This is the one I used to have. Works good.
I found a Xircom credit card 10/100 56k modem combo card. It kept
getting device timeouts. Don't know if it was a bad card or what.

Yeah, I've been installing packages from the Cobalt. I'm starting to
build up a little kit of them if anyone's interested. I just started
building stuff at 2.0. I had some stuff at 1.6-release but I'm
starting over now.

I plug it in while booting CE and it works fine. It's kind of awkward
sticking out of the back of the machine though. And yes, it is slow.
Slower than netbooting.

About to test this.

After netbooting an entire distribution, I just ran "startx" as root
and it worked. The touch screen is a little hokey but sort of works.
But it's sloooow. I'm not even sure that it's useable. I'm building
blackbox because that's about the lightest desktop I can use and still
feel like I'm getting something done. I'll see how it goes.
Netbooting an entire distro is WAY faster than using the USB storage
device. I started building some stuff but it's really slow. I'm going
to leave building to my Cobalt, which is only slightly faster. This
thing is quite useable as a terminal, but I'm not sure about X. It was
Testing the new partioning scheme of the CF card. I'm a little worried
about that because if I can't use a partitioned CF card then the
useability of this thing is not so good for me.
Can't get audio working. I made a small try at it. It would be mono
anyway, which isn't too good.
Overall I'm not sure that this thing is going to suit me, but it's fun
to play with.
