when you have the iso image, you can do > md5sum <isoimage> to check for a correct download. When you have burned the CD, insert it and start the install. You can do the mediacheck for all CD's before actually starting the install. You can always quit after the mediacheck. Hope this helps, Marc On Thu, 2004-06-10 at 08:48, Lin Tse Hsu wrote: > Hi.
