An updated IOS image sent to replace one subject to the IOS Heap
overflow vulnerability arrived at 16,855,588 bytes. TAC rep said the
min requirements are 10MB dram, 16MB flash. Problem- the flash card
is around 16,500,000 bytes, about 300k short of holding the image.
I have a 20 MB flash card, but it appears the 1600 won't see anything
above 16 MB.
Is there a way to make the 1600 recognize the full 20 MB of the flash
card? (In case it matters, router has 8MB base mem + 16 MB dimm).
TIA for any help.

Hi Jay,
1600-R series router images run from RAM.
The run from RAM images are compressed and have -mz in the filename.
Because the run from RAM image is stored in Flash in a compressed
state, and decompresses into RAM at bootup, less Flash and more RAM is
required.
Verify whether the image is a run from a Flash image ( with a -l in the
filename ), or a run from the RAM image ( with a -mz in the filename ).
When downloading images from Cisco Downloads:
http://www.cisco.com/tacpage/sw-center/
The run from RAM images are listed under 1601R-1605R.
Sincerely,
Brad Reese

Do you know why the router only recognizes 16 MB of a 20 MB flash
card? It is a completely unpartitioned flash card that other devices
see as 20 MB available, but the 1600R only sees the first 16 MB.
Are the 1600R's limited in how much flash they can recognize?

Jay,
You may wish to investigate:
PCMCIA Flash on the Cisco 1600 Series Router is implemented using one
slot for Fast PC cards ( up to 16MB ).
