Bootup stops after memory check (Tyan trinity 400, s1854)

Hi,
I have a Trinity 400 that once worked fine, but now it only boots up to the
point where it finishes checking memory and then stops. I've tried changing
the cmos battery, a different (more powerful) power supply, disconnecting
almost all drives, but still nothing doing.
Does anyone have any ideas on what I might try next, or what might be
causing this? Thanks.

Have you tried a different keyboard? If the bios is set to halt on all
errors, a bad keyboard could prevent it from booting. I've also come across
a bad surface mounted coil in the 5v power trace for the keyboard circuit
that prevented a board from booting.

I had a similar symptom when I first put together my system (Trinity
i7205 (S2662). In my case it was due to the floppy drive connector
being not fully plugged in at the diskette drive connector.
