Trying to upgrade debian - won't boot off CD
I've got an old (2.4.27-2-386) version of debian on one of my machines. I want to upgrade it. I got a new small distro onto CD, set the target machine to boot from the cd rom drive, but it just comes up with the old version. Is there something else I should be doing to do this upgrade? Shouldn't it be booting off CD if I've set it to do that in the firmware?
