    Default problem with Lombard cache memory

    I just started getting the message when I start up my 333 MHz Lombard (OS
    9):

    "The built-in memory test has detected a problem with cache memory. Please
    contact a service technician for assistance."

    It still starts up and runs. Any one have any idea if that is referring to
    cache on the daughter card or logic board what it's going to cost to fix?

    Today, I tried some more experiments. I used G4 cache software that turns off
    the L2 cache. It registered an error message immediately that said the SRAM was
    not present. Presumably, this means the cache memory is defective. I removed
    the CPU card and scanned it with an 10X magnifier and could not see anything
    obvious in the way of bad solder. Wish I had some means of testing the cache.
    Maybe TechTool Pro will tell me something.

    Tech Tool Pro 3.0 said the cache was "unavailable." I take that to mean it's
    missing or dead. I did get a reply from a vendor on eBay that the cache is on the
    CPU card as I expected. The two RAM chips are also mounted on this card, one on
    top and one on the bottom.
