I have a strange situation with a 2960s. After attempting to upgrade the IOS version to 150-2.SE4, the switch appears to load the image and boot normally, but then seems to fail and start over again to load the image (more slowly the second time). Eventually the boot process fails and leaves you in boot loader mode.
As background, the switch was upgraded from the boot loader mode using this syntax:
archive download-sw tftp://10.10.222.222/c2960s-universalk9-tar.150-2.SE4.tar
Also, the flash was formatted and clean prior to the upgrade.
Pasted below is an abbreviated version of what I'm seeing when the switch tries to boot.
Also pasted below is the output of the "set" command from boot loader mode.
If anyone has seen this movie before and knows how to resolve it, I'd really appreciate your help...
When booting I see this:
Using driver version 1 for media type 1
Base ethernet MAC Address: 38:1c:1a:3a:41:80
Xmodem file system is available.
The password-recovery mechanism is enabled.

The system is unable to boot automatically. The BOOT
environment variable needs to be set to a bootable

Hi 2ndcongress,
Just a guess -- I think your configuration register might be misconfigured. Each of the bits in that 0x3000 entry point need to set correctly otherwise the switch won't work correctly. Based on my research it looks like you need to set the least significant bit to on and it will load the image from flash. So the entry point would be 0x3001. Again, each of the 16 bits in that configuration register has a different meaning, so changing that least significant is only a starting point. Other bits could be misconfigured too. Hope that helps!
