Cisco ADSL router come with 24MB Flash memory and 128 MB Memory by default, can we get another memory slots for either Flash or memory and install them later (Flash 24to28, 24-36, or 24-52), (DRAM 128to192 or 128to256). i.e is there is a free slots for both flash and memory or we shall replace the exisiting flash and memory with the new upgrade?
The default 877 flash of 24Mb is made up of 20 MB of onboard flash memory and a 4-MB flash memory card. You can replace the 4Mb flash card with a 32Mb Flash card to give you a total of 52 Mb of Flash. As for DRAM, the 877 has 128Mb of onboard DRAM which you can supplement with a 128Mb DIMM to give you 256Mb in total.
