Howdy, here is a good slow mirror...
This is the PowerPack edition. There are actually 3 more CD's out there. You can find them all on overnet.com. That might be the fastest way to get them. There are also bittorent links to them.
Here is a good windows program for deciphering md5sums...
If you're burning iso's in windows its pretty handy. If you burn them in Mandrake, the program: k3b, (not a very intuitive name), will check the md5sum automatically.
After reading the thread, I can relate similar experiences. The Eltoredo CD, (fancy name for bootable in an x86 machine), can have problems being burnt and read in some older CD burners. However, they usually work in most ROM's when burnt correctly. Burning an iso at a slower speed definitely helps. Nero has a special, un-intuitive way of burning iso images, I think you go to File>Burn Image...> then select your iso.
Hope the links help everyone get into Mandrake. Itís my favorite flavor!
