You'll have to show me where you get this from because it doesn't make sense.  There is no reason I can see for this to be true.

Never heard before too!! it should be a "nonsense" and unusefull behaviour!


Just to check my reasoning, I located my A3k schematics, C= P/N 314677-01.  The clock and ROM chips are on sheet 3.  It clearly show that the battery never powers the ROM.  In fact, unless D191 were to fail, no current could flow from the battery to the 5V rail.

My A3k wouldn't get past the CLI with memory on the motherboard and memory on the CSPPC.  Booting with no s-s, I ran avail and it reported something like 2.5GB of free RAM.  Perhaps the CSPPC maps something to the range the mobo RAM normally occupies.
