Config-Registry value of 0x2101 means ignore the boot variable statement. 

Change this to 0x2101 using the command "confreg 0x2102" and then reboot the appliance. 

Make sure you are still consoled in when rebooting the appliance because it makes troubleshooting a whole lot easier.

Dear Leo Laohoo,

Please see here the output if i change the Config-Registry value of 0x2102.

He could not find a BOOT environment variable.

[Leo Laohoo]

Can you please post the complete output to the command "dir bootflash:" or "dir flash:"?

Config registry value can be changed using the command "confreg 0x2102".

On line bold, it a new IOS I upgrade but he can run correctly because this IOS work with RommonVer cat4500-ios-promupgrade-122_31r_SGA7 or most recent currently I have this RommonVer=12.2(31r)SGA
