ALSO ... if doing to VMWare, you can just point to the ISO file as a CDROM and boot from it directly. Try to install from that and see if it passes the media test. That should help determine if the problem is a bad DVD image when burned or some kind of kernel boot issue. Not passing an md5sum/sha1sum can be caused by many things, some of which are hardware based but do not affect the install. -------------- next part -------------- A non-text attachment was scrubbed...
