Not enough address lines.
I'm told by the Cisco folks that the reason for the things that look "ob-
viously brain-damaged" in retrospect on the 25xx are because it was Cisco's
first custom VLSI implementation of the IGS architecture and they didn't want
to make major changes. This seems to make sense.
This means that if you want more than 18MB DRAM (16 main + 2 I/O) you need
to move out of the 25xx family. However, since probably the only reason for
wanting that much memory is maintaining a large routing table, you should
know that the 25xx doesn't really have enough CPU power to handle updates for
I'd look at your show mem output and see where all the RAM is going - if
you're not doing full routing, I think you have a memory leak.
