Neo Platinum won't post after BIOS change...

Question

I changed a few BIOS settings in my machine.  Everything was working fine before; all I switched (to my recollection) was changing the boot order and also switching from Manual to Automatic for High Performance Timings (named something like that).
After doing this, the machine won't even POST; I get a ~2 second long beep shortly after turning the machine on, and this beep repeats with a ~2 second pause between each beep.
I have tried:
- taking out the memory in bank 2
- taking out both DIMMs
- doing the JBAT1 CMOS reset (pins 1-2 going to 2-3)
- doing the 'remove the battery' CMOS reset
- doing both the JBAT1 and battery reset approaches, leaving it in 2-3 and battery out all last night
After all of these, there was no change -- I still get the beeps.
D-Bracket seems to have the bottom left light red, and the rest green, if I recall.
Any guesses?  Thanks.

Ah, to clarify -- I looked at the Basic Troubleshooting Guide for the exact description of what the D-Bracket is showing. It looks to be "Initializing Keyboard Controller".
Maybe someone else knows -- in the list of all of the D-Bracket codes -- which are meant to be green and which are meant to be red? (As the page has white and black..so I'm trying to confirm that I'm right in mapping correctly between white/black and red/green; if my mapping is backwards, then it really means "Assign Resources to all ISA").
As for possible memory issues -- if I hadn't changed anything in the BIOS other than memory timings -- wouldn't resetting the CMOS have gone back to default timings (which were working a-ok until I made that BIOS change).  (Plus, I don't have any other RAM, so I'm looking for other things to also try
