I have read many threads on this subject, and have not been able to get any of them to work...
My problem started by saving a config file onto the 6500, and subsequently when the 6500 is booted, it comes back with the error about the first file on the flash is not an IOS image as I had not configured boot system sup-bootflash:<filename> when the 6500 was up.
I have been trying to follow the published recovery procedure, to no avail: i.e. put a disk in the supy with the IOS on and do boot disk0:<filename>. In SP rommon, a dir disk0: comes back with "device does not contain a valid magic number", even though this came from another 6500 that has booted off of the disk.
What I can see is in SP rommon, dir bootflash: shows a valid image, for which I can boot from SP rommon to RP rommon.
At RP rommon, if I try to dir any of the file systems shown by the dev command, no files are found. If I try boot sup-bootflash:<filename>, the RP boot just crashes, although at this point I can then dir bootflash: and see an image, but I suspect at this time it has gone back to SP rommon, and that is why I see a file.
The fact SP rommon boots from the bootflash:<filename> image must mean that the image is not corrupt, so I would have thought there should be a way of getting the RP to boot from it (hence trying boot sup-bootflash:<filename>).
Any ideas greatly appreciated, as this is due to go live on Wednesday...!

Although the situation has improved, I'm not quite there yet:
I had the flashdisk taken to another site, where on insertion, messages about the format came up (this was a new flashdisk out of a box). I have now formatted it in another 6500, copied the IOS on and had it taken back to the broken 6500.
At SP rommon, a dir disk0: now returns the IOS filename.
If I boot disk0:

I also tried the xmodem download of a boot image straight into the RP, as per the recovery procedure.
Still no joy.
I eventually got a hardware support call out for it, and the engineer replaced the Sup720 saying "the software on the card is corrupt".

Hi Foster,
A few basic steps which you can try is to verify the disk using the 'verify' command and if possible do update the IOS version you are using.
Try to reseat the flash card in the slot once again properly and let us know what happens.

Thanks, but as I put in the previous post, the sup720 has now been changed out and it is working.
I just put an update on in case anyone came looking for a fix to their problem, but could not see how you are supposed to "close" a thread on the forum.
