I am trying to upgrade the IOS on my Catalyst 4506 with Supervisor Engine IV.
This switch has 64MB of Flash and 512MB of DRAM.
The current IOS is bootflash:cat4000-i5s-mz.122-20.EW.bin and I am trying to upgrade to cat4000-i5k91s-mz.122-25.EWA4.bin.
I have successfully TFTPd the new IOS to bootflash, (when I type show bootflash I can see both IOSs), however when I reload the switch it complains about an invalid something or another and gives me a rommon1>.
If I type boot at rommon> the switch boots with the old IOS and functions properly.
I tried adding the line boot system flash cat4000- i5k91s-mz.122-25.EWA4.bin to the startup-config, but I still get the same problem.
