2. the IOS to upgrade to from System image file is "flash:c1841-ipbase-mz.124-3i.bin".

3. The router is a Cisco 1841.

Cisco 1841 (revision 7.0) with 114688K/16384K bytes of memory.

114MB+16MB = Rounded to 128MB

HTH,

Or without rounding:

114688KB + 16384KB = 131072KB = 128 MB

That is is the DRAM, how about the FLASH memory?
