I've been asked to help a customer who has a Sup II fitted into a 4500 chassis. He has tried to upgrade the IOS on the switch and somehow in the process lost the boot helper image. So now the switch is at ROMMON, and wont load the IOS, probably due to the missing boot helper.
Documentation on Cisco's web site indicates that this probably needs a RMA swap out, anyone else had this problem and managed to sort it out?
I was thinking of suggesting they use a PCMCIA flash card with a valid IOS image and boot helper in slot 0, but I'm not sure that would work.
