[cisco-voip] Largest CF that a 2821 / 2851 will take?

[Robert Kulagowski]

I've got a bunch of 2821/2851 routers which were all shipped with the 
standard 64MB of CF.

64MB of CF isn't large enough to store two IOS images at the same time, 
so our current practice is to delete the existing, then load the new 
one.  So, there's a window where it's possible that you end up with no 
IOS and a dead router.

1GB CF cards are available at NewEgg for $9.79; can't really even find 
the "small" CF cards in the 256/512MB range anymore.

Is there a limit to the size of the filesystem/CF that the router will 
format?
