Some of models in the 2500 series have 2048K RAM modules soldered to the
system board. Some do not. My routers are mixed as to which ones have it
and which don't.
The number to the right of the '/' represents the amount of memory that the
IOS uses for I/O buffering, called the 'iomem region'. By default in a >4Mb
configuration, the IOS uses 2MB of the total DRAM for I/O. A good reference
for Cisco architecture is the Cisco Press 'Inside Cisco IOS Software
Architecture'. Your question is covered on page 72.
