This might be of some interest for people having this particular
hardware, so I am writing this FIX report to the list:
The problem was:
>
> Dual 200MHz Pentium Pro machine:
> TYAN S1662-AT-001 board
> 100 Mbit Kingston KNE 100TX ether card with DC21140 chip
>
> After upgrading to RH 5.2, kernel 2.2.X (checked with X=1,6),
> and kernel-level NFSD,
> SMP-compiled kernel booted fine, bo there was absolutely NO NETWORK
> The card got detected (both with "tulip" and "de4x5" drivers), the
> eth0 interface was set, but no ping, no interrupts, no packets.

THANKS Evan! I upgraded to the newest BIOS from Tyan (ver. 5.01) and it
works just GREAT! One change that I noticed in "/proc/interrupts"
is that the network card IRQ is now reported as 'IO-APIC-level'
instead of 'IO-APIC-edge'. I have no idea what it means ;-)))
but the 'level' works and the 'edge' was no-good.
One REMARK for followers: write down all BIOS settings before the
upgrade. One has to clear CMOS after the upgrade and the default "clear"
BIOS settings (at least in my case) were not proper - only 64 of 192 MB
RAM was detected. After changing all settings to the original ("old"),
everything started to work as expected.
regards for all,
Michal.
