[MLUG] crc error

Thanks to Padraig's advice I did eventually get registered with Red Hat. This led me to get onto the rpm so as to start to update the installed packages. As "instructed" I first downloaded the "up2date" program files, installed them & executed. (I downloaded 2 files--one that was just the up2date version, and another one that mentioned up2date for gnome. I wasn't sure which one(s) I needed so I did both. It took several attempts, so I ended up with a few "extra" copies. (Couldn't figure out if I needed to create a separate folder or if the download program would create them automatically--general confusion. Plus I had downloaded them the day before, but hadn't managed to completely install. The packages looked "open" but I wasn't getting indication of them being installed.) Finally seemed to have gotten somewhere, but I couldn't tell which of the various multiple copies had been used, and didn't know if I needed to keep them in those file folders or not. (This may be relevant to what happened next. . .)
Next I was going to download updates for 20 packages. But when it showed the files to confirm for download, there were only 2: something like glibc i386 and glibc i686. I wasn't sure if I was supposed to do them both or not (because my machine is an i386), so I ticked the box for i386 file, and did the download. (it only took a second or so because it was only 1 Kb.) Then I couldn't find it. I delected the "extra" rhn download packages that had the extra up2date files I had previously downloaded. I still couldn't find the most recent glibc i386 file I'd downloaded.
I may have inadevertently deleted what I'd downloaded as I don't remember ticking the box to show me the file after it had downloaded. (That is, maybe it was sitting hidden in a folder I deleted in which I only saw the extra copies of up2date.)
Then the screen froze completely. So I tried to reboot. At the point when it was starting to Uncompress Linux I got the message: crc error System halted
Tried again to reboot, got a bit further in the process but then got: Kernel panic CPU context corrupt (just above it: CPU0 Machine Check Exception)
I've no idea what I've done wrong and how to get out of this. I have no idea how serious or unserious it is. (I do have the redhat 9 discs I originally installed from.)
Whenever I try to reboot I get either the crc error or else the CPU context corrupt message.
I have another computer connected to the 56Kb phone line so I can send this email! So that is very good news.
I will be grateful for any suggestions about what to do next. It's the linux server that is affected. I really didn't think I was doing anything so adventurous that it could lead to a kernel panic!
