Only the more recent revisions of the Triton-II chipset support ECC.
The information I have says that you need at least the A2 stepping of
the 82439HX chip, which would be marked SU102 or later.  As near as
I can figure you should use x36 (parity) FPM SIMMs rather than x32
(non-parity) FPM or EDO SIMMs.  There's probably a BIOS setting that
needs to be enabled as well.

That's probably missing as well.
