I tried the link and it worked fine, so I can't explain that. Here is another link:

This will take you directly to the download page on the Mandrake site. Scroll down the page a bit and you will see a long list of the FTP sites. Assuming you have a computer above a 486 you will want to get the i586.iso file. Then you will have to burn the iso's to a disk. You should be able to find directions on how to do this but is not just post back and I'll coach you through it.
