I have 4 tyan s2882's. 2 with 244's and 2GB of ram and 2 with 246 and 4GB 
of ram. I don't appear to have bad parallel ports or bad ethernet 
interfaces. They're running fedora core 3's 2.6.11 x86_64 kernel
(2.6.11-1.14_FC3smp)... I cna't tell you what bios version off the top of 
my head but i can reboot one tomorrow if that helps.
