So, did you try at all to figure out why the DA logic board won't
turn on?

SOLVED: The computer refused to turn on at all. It occurred to me
then, that the people who gave it to me never mentioned if it
worked or not. So, I swapped in a Quicksilver Motherboard and Power
supply and the overclocked 800MHZ processor. I had to build the
forth mounting post for the processor out of nuts and bolts because
the DA case had not place for it. Everything works perfectly, and
OS 9 doesn't mention anything about cache failure! Thanks for the
help!

So someone gave me a single 533 digital audio g4 yesterday. I
successfully put a 733 quicksilver processor in it, and then
decided to overclock it to 800MHZ. I "successfully" did this,
except that when OS 9 starts up it says that the built-in memory
test detected a problem with the cache memory and to contact apple
support. I zapped the PRAM, reinstalled OS 9. Nothing worked, I can
still use the computer though and it recognizes it as an 800MHZ G4
with 256kb level 2 cache. Thanks in advance!
This is a little out of my area of expertise, I've never had much
experience with G4 PowerMacs, but I thought that both the 533 DA &
733 QS were considered "road apples" because of their miniscule L2
cache? The "normal" size of a 733 QS L2 cache IS 256 KB, so if
that's what you're seeing, it IS correct. It would seem advisable
to get a different CPU with a larger L2, irrespective of whether
this L2 is functional or not.
Also, I've seen that message in OS 9 before on Macs that would also
boot OS X, for example, I've got an old PowerBook 3400 with both OS
9 and OS 10.3.9 installed. In OS 9 I see the message, but in OS X,
System Profiler shows the L2 cache and says it's functional. I
decided that the warning in OS 9 was likely wrong, but I'm not 100%
sure. There is an old utility from NewerTech called "Gage Pro 1.1"
which if I remember right will show your L2 functionality in OS 9.
