Ah, good point. Those instructions were from when we were upgrading to
11.2 a couple of years ago. Back then, our boot ROMS were 10.2, IIRC,
so all of these steps were necessary. I haven't done many upgrades on a
2500 series since then. I have done a few and I forgot that it was a
little easier now. It's still not as easy as a 2600, though. Those are
really painless, especially if you have loads of flash memory.

You are right but if your bootroms are later than 10.x they then
contain the boot load helper which does all those manual steps John
listed for you. In which case you need only set you default-gateway
and
then do the "copy tftp flash" If under the sh ver the bootroms are
listed as 4.1.x or 5.1.x add 5 to the first digit to get what IOS
these
bootroms are, i.e. 4=9 and 5=10. Don't know why they ever did that:(
