AGS+ boot hang due to memory corruption?

    Ok - I've got an AGS+ w/the CSC/4, bootstrap version 5.3(4), the
    daughter flashcard and it's trying to load from that flash (I'll
    assume - not 100% sure) version 10.3(4) GS3-K-M. It gets as far as the
    vefsion banner for the IOS and then it sits there. I did let it set
    there for over 2 hours once and I finally caught it proceeding to
    this:

    I'll assume this is bad memory on the flash card or is it DRAM? Any
    ideas???

    Maybe, but the heap problems are fairly high-level. Sure, bad memory
    can do most anything, but this feels more like software confusion. IIRC
    your NVRAM is actually RAM with a lithium backup battery. I'm not sure
    how things will behave if that battery is low. You might want to check
    and/or replace it.

  3. Bad "magic" numbers usually point to a corrupt NVRAM or flash module. Is
    this an item that can be replaced on the AGS+? I have no idea...sorry!

    BTW, where did you find this antique? Those things are ancient...hehe.
    Let us know if you actually get it working!

    Thanks to everyone for their help thus far. Yes it is an ancient piece
    of hardware but with 4 ethernet ports it still has its purposes. I
    actually picked it up for nothing. The Flash card is a daughter card
    sitting on top of the main system board and was optional through the
    products' lifetime. It is replaceable; although where I might find
    another one I am unsure. The CSC/4 processor borad - I have seen them
    available on Ebay and might just pick one up for a spare. It holds the
    DRAM and the 68040 main processor.
    I will check that battery Dan - good call.
