[SUMMARY] How to update disk firmware on system disk?

Well, this was pretty stupid, sorry for the noise. I had
previously been given the recommendation to boot from CD and
then put in CD with firmware patch on it, I wanted to verify
if this would work.

Consensus is it won't, system will probably panic during firmware
update which is a Bad Thing.

Better to just boot from CD and then either:

1. Bring up network interface and NFS-mount partition with firmware
   update on it or ftp/scp the update into /tmp; or
   
2. Boot from CD, insert CD containing update and copy it into
   /tmp (essentially into RAM), then reinsert OS CD. This way
   OS CD is available during update. [I'm still paranoid about
   there being some kind of panic...I'll avoid this one.]

Of course one could always put in an extra internal disk with the
update on it.

Thanks so much for all the out-of-office replies. Really folks, if
it were up to me such replies would result in being bounced from
the list. Congratulations to the following who were lucky enough
