6500 booting from flash

[rishad ahammed]

I need to boot my 6500 from external flash, and I put the command "boot system flash s72033-adventerprisek9_wan-mz.122-33.SXI13.bin" to set the boot variable. But still the switch is booting from flash sup-bootdisk: and also the boot variable is set to flash sup-bootdisk:  .  Can any one please tell me how to solve this issue

this is the show run

boot-start-marker
boot system flash sup-bootdisk:s72033-ipservicesk9_wan-mz.122-33.SXH4.bin
boot system flash s72033-adventerprisek9_wan-mz.122-33.SXI13.bin
boot-end-marker

and 

Router#sho bootvar
BOOT variable = sup-bootdisk:s72033-ipservicesk9_wan-mz.122-33.SXH4.bin,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2102

Hello

i would suggest to change the boot variable to contain both old and new iOS but have the new iOS try to boot first

no boot system

r
boot system flash:s72033-adventerprisek9_wan-mz.122-33.SXI13.bin

boot system flash sup-bootdisk:s72033-ipservicesk9_wan-mz.122-33.SXH4.bin

Sh boot

External flash?  Like the CF?  

It is known as "disk0:".  So your boot variable is "boot system flash disk0:IOS_filename.bin".

it will be showing disk 0: while copying but there no disk0 for the bootsystem command. Thank you for reply

Ok, if the command "boot system flash disk0:" not allowed, can you please post the output to the command "dir disk0:" and the output to the command when you enter in configuration mode? 

All my Sup720 have "disk0:" as a secondary boot variable.

I tried all of the above .... but it was not working, Then I copied the ios from flash to sup-bootflash. Now the ios is new one in sho version command, but still there is no change in sho bootvar command.  Any way I have managed to boot the new IOS, Thank you all for your reply
