cisco 3620 copy flash command
I want to boot my 3620 from a new 20 MB PMCIA flash card. I already have the router configured in TFTP console session using hyperterminal cli emulation.

I tried this command:Router#copy flash:c3620-is-mz.121-3a.T
and got:
Router#copy flash:c3620-is-mz.121-3a.T
Destination filename [slot0]? c3620-is-mz.121-3a.t7
%Warning:There is a file already existing with this name
Do you want to over write? [confirm]n
I phrased the command this way becasue it looks like in show version the Sim based flashed is just called flash and my 20 mb PMCIA card is slot0
The routers's response seems to indicate that it think that slot0 is onboard flash.
Where am I going wrong here?

ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Your image appears to be corrupt, or your flash memory card is bad.

Well in that case It could not hurt to reformat card and try the copy again. If the check sum is comparing the original image to the PMCIA card the the problem is most likely on the card side.I just boiught this card. New supposedly but who knows.
ASKER
Yes. it looked like an overwrite to me too . I tried your command and got CCCCCC
but the checksum failed.
Verifying checksum... invalid (expected 0xBC40, computed 0x3E95)
9937896 bytes copied in 195.640 secs (50963 bytes/sec)
Router#how version
Trying Dir flash commands:
Router#dir flash:
Directory of flash:/
1 -rw- 9937896 <no date> c3620-is-mz.121-3a.T7
16777216 bytes total (6839256 bytes free)
dir flash0:
Router#dir flash0:
Directory of flash:/
1 -rw- 9937896 <no date> c3620-is-mz.121-3a.T7
How accurate is Cisco Checksumming? Should I try to set the register to boot to flash PMICA card slot0 and cross fingers or try erasing flash and do another copy attempt or try a working config-copy?
