I got a 6509E with 2 x 720-3b's
One new with a Bootdisk of 512Mb
One old with a bootflash of 64Mb
what I have for a problem is that the old 720 won't boot at all from the Flash but when I put the 512Mb bootdisk into the old 720 then it boots without a problem.
What I have tried is to remove the Bootflash and boot from disk0:
and get the following errors - see text file
Please tell me what I am missing/need cos I don't have much of a clue with anything bigger than a 3750 :-/
The flash cards that I use in disk0: are 128Mb and 512Mb in size
