Well, is this a flash upgrade or CatOS upgrade, I mean did you upgraded the flash memory or software in it ?

Anyhow, here is the procedure for sup I.

There stuff has a build in, a very small version of CatOS, burnt in the ROM so you can TFTP the full image to flash and run from there. Too boot from that image;

1. Remove sup I, yes, this is the way to do it.
2. Locate the boot Jumper, for Sup I FX (5005-5006) this is J25 (jumper 25 / boot) and for Sup I TX (5009) this is J24 (diag on).
3. Place a jumper connector (this is unfortunately not available on most cases (look one from your IT department, from you old harddisks or somewhere else :)
4. Reinstall SUP I and poweron, you end up in boot mode.

2 options to load the image is to use Kermit protocol and TFTP, kermit should be avoided when possible.

Rest is : copy tftp slot0:
verify slot0:c5aaa-yyy-xx.121-8.bin
shutdown
remove Sup I
remove jumper
reinstall
boot :)

Thats it... Hope this helps...

Correction:
I am not exactly sure about the syntax of copy and verify commands in the boot prompt, but you will easily figure out once you get there. Sorry I don't have a chasis at hand at the moment.
