[nsp] Cisco 3660 "BAD RAM"

[Beprojects.com]

Does anybody have a link to the Cisco "memory map" page?  I am looking for
the one that says what locations are used for what.  I have a 3660 that
crashes on botup with the following message:

System Bootstrap, Version 12.0(6r)T, RELEASE SOFTWARE (fc1)
Copyright (c) 1999 by cisco Systems, Inc.

Bad RAM at location 0xA0000000: wrote 0xA0000000, read 0xA0000008


No matter what RAM I put in there, I get the same message.  It almost seems
like a bad controller card.

Thanks.
