Hans,
One last thing. Someone else on this list mentioned that you
can put an 8 MB FLASH in the first slot and a 4 MB in the second
for a total of 12 MB useable FLASH. I tried this and it works.
So, for your 10 MB IOS example, this is an option.
Caveats:
*The Flash sizing reports 16 MB of Flash (the 4 MB SIMM is
mirrored in the memory map).
*When you erase it, you get errors above 12 MB. Ignore these.
*When you load an IOS, make sure it is smaller than 12x1024x1024
(12 MB), and it will work properly.
*If an IOS larger than 12 MB is loaded, you will always get
checksum errors.
*You should probably mark the router on the outside since none
of the show commands can detect this situation (12 MB FLASH
is not a supported configuration)
*Definitely not recommended for production routers.
If you don't want to spend the cash for another 8 MB SIMMS (or
if you have a poor router with 2 4MB SIMMs already), this is a
good way to get more useable flash at a minimum cost.
