Every so often, while booting (in verbose mode), I see a memory test failure,  
giving an address, a bank, etc.  It doesn't always appear, and it doesn't  
appear long enough to write down, so I don't know if it is the same error.  I  
have had occaisonal flakiness after seeing one of these, but nothing major.

I want to see how repeatable the error is, and if so, on what SIMM it lies.  I  
got into the monitor ("ROM Monitor 2.0 (v58)" to try to run a dram test from  
there, but such a test doesn't appear on the list of commands given by ?.  Is  
there a way to do the power-up DRAM tests from the monitor?  What about "boot  
extended diagnostics" as given in the boot parameters (p) command?

This is an original cube, upgraded to 68040, with 24mb of RAM, running release  
3.0.  Thanks in advance,
