McHugh, Have you tried to redownload the IOS image and verify you have the correct checksum (MD5) ? It is possible the IOS you have is now does not have good integrity.

I have tried it several times before with the same results. Anyone know a fix for that? I have 15.x file with 16mg flash and 16mg dram so that should be enough dram and flash to hold the image. thx Randy Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=51840&t=51834 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
