What exactly happened that makes you say that it failed? How far did you get, and what was the failure?It was some time ago, and don't recall all details. I thought it was a CentOS 5.1-specific issue, but when I had to reinstall and used Scientific Linux 5.1 it didn't work either. I will redownload CentOS 5.1 x86 and will run it under vmware, so as to report the issues in the list.Regarding SL 5.1 x86 DVD being the case as the most recent that I retested it under vmware, the image passed the sha1sum check, burned it and verified at the same time with nerolinux, but during installation the "medium checking" showed "FAILED", and when I proceeded with installation something very bad like kernel-panic (but not sure if it was kernel-panic) occurred and it rebooted. I have checked my system with memtest86+ 1.70 with no problems found with the default tests. Now I am redownloading the CentOS 5.1 x86 DVD install image, and I will use the image itself first as a virtual DVD under vmware, and will try to verify the medium during install and see if it proceeds OK with installation. If it succeeds, I will burn it to a DVD-RW and retry the same things. SL 5.0 x86 DVD and CentOS 5.0 x86 DVD work OK.
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.
