This, unfortunately, is easier said than done.
I made the mistake as installing Linux on my 4 year old Sony Vaio... Something that was a small miracle in itself. The CD drive is PCMCIA, and is sketchy at best. I still haven't perfected the skill of switching CDs, and for some reason it doesn't like recognizing my disk 2 of FC1. Either of them.
I tried this last night, and got down to installing the RPMs manually off the disk, using the details of the update to know which packages I should install (Not that some of them aren't self-explainatory). This has been working so far, but there must be an easier way!
