Installed from boot disks from a LXF DVD Debian 3.0 stable. I haven't gone for 
anything fancy on the box, although I might look into a 2.4 kernel for the 
laptop. This is the Pentium1 that I've been hacking around for the last 8 
years or so (I bought it when Win95 was just 3months old, awww), I don't know 
that a 2.4 kernel would give me much performance improvement.

It does, but only with lots of unnecessary Cat5!

No. I don't THINK it's the switch, but I will check - I had the same light 
results with the router.

Oh I had great fun with P&P. I had disabled it so completely in the BIOS when 
I installed Mandrake 7.2 (with only one NIC) that it disabled the entire PCI 
bus. Which was nice. It took me a fair while to work that one out. It 
certainly appears that all the problems are in the BIOS.

No, just figured that it'd be more reliable to get the hardware sorted.

No Microsoft on this LAN. Mandrake 9.1 (not using DHCP), Mandrake 9.0 (not 
using DHCP but offering a server if necessary), there's a DHCP server in the 
router - I don't like to think where they got that code from.
