Hello


I have a Cisco 7301 and we are trying to get BGP going using a 4 byte ASN. However the IOS that was uploaded is not liked by the router.


The router keeps going into a boot loop a few times and then it goes into rommon mode. Trying confreg 0x142 or 2102 does not help.


A snippet from the boot output below:

Self decompressing the image :

################################################################################################################################################################################################################################################ [OK]


(mem checks cut out)


%ERROR: Invalid IOS image for this platform.



System Bootstrap, Version 12.3(4r)T4, RELEASE SOFTWARE (fc1)

Are there any suggestions how I can resuscitate this baby? Like erasing the IOS from rommon or even set a jumper on the motherboard to clear everything off and let it load a basic startup config?

Hi Leo


Thanks for the assistance, but unfortunately it looks like the only way to fix this is to use a Cisco flash card with the IOS we want on it, in order for this baby to boot. She is as dead as a doornail :(
