Hi,
I have this command configured on a Cisco 6506-E: boot system flash sup-bootdisk:
The IOS image is on the sup-bootdisk.
6500#dir sup-bootdisk:
Directory of sup-bootdisk:/
1 -rw- 74689508 Jan 4 2009 01:26:48 +01:00 s72033-ipservicesk9_wan-mz.122-33.SXH4.bin
2 -rw- 33554432 Jan 4 2009 03:49:32 +01:00 sea_log.dat
3 -rw- 32193 Sep 9 2015 11:50:36 +02:00 tftp
512106496 bytes total (403824640 bytes free)
I need to upgrade the ios image. Can I have two different IOS images on the sup-bootdisk? In that case, How can I tell the switch which one it must use to boot?
Thanks in advance.

Yes you can.
In that case, How can I tell the switch which one it must use to boot?
Important: Verify the config-registry value is 0x2102.
Use this:
config t
boot system flash bootflash:NEW_IOS.bin
boot system flash bootflash:OLD_IOS.bin
boot system flash bootflash:
end

Thank you for your quick response.
There is something that I don't understand. My old IOS is in sup-bootdisk, it isn't in bootflash. In fact, my bootflash is empty:
6500#dir bootflash:
Directory of bootflash:/
No files in directory
Is it possible to use those commands with sup-bootdisk instead of bootflash:?
Are these commands correct?
boot system flash sup-bootdisk:NEW_IOS.bin
boot system flash sup-bootdisk:OLD_IOS.bin
boot system flash bootdisk:
Thanks.

Yes, change my recommendation of "bootflash:" to "sup-bootdisk:".
