Not enough Disk space for upgrade

["White, Bob" <rcwhite sbec com>]

Hi All,
I messed up this weekend.  I tried to install RedHat 5.2 as an upgrade to my
RedHat 4.0.  I assumed that the upgrade would remove all the programs it was
upgrading before installing the new versions.  It complained about half way
through the installation that it had no more disk space and now I can boot
the thing.  It gets to a point in the initrc and locks up.  How can I boot
the machine to remove the files that have corrupted my machine?  Is there a
way to break out of the install program after it boots my machine?  Sorry I
can't find my boot disk for RH 4.0.
