I used the provided md5sum to make sure what I was burning was correct. I then burned the disk with k3B verify, for both the md5sum and the actual download file, and burned the DVD with "verify" which succeded.

At the bottom of this interminable list, instead of the former quote, it now says: "Use of these features in this kernel is at your own risk." I'd really like to try this system, but it defies me. doug

From the age of the BIOS (2010) and the date of RHEL-7 coming out 2014.. you are at the cusp of upstream hardware support. The problems you are describing could be anything ranging from BIOS/Mobo incompatibility to a whole host of things which would take a while to debug. I would do the following: 1. See if CentOS-6 runs on the hardware. If an ISO fails to boot either via USB or DVD in a similar way then it may be a hardware issue. 2. Download an older version of CentOS-7 from vault.centos.org and see if that will install. 3. Start looking at the hammer boot options which various motherboards need. These can range from acpi=off noapic or a slew of others. [Google for ones which might match your hardware.] There are 10's of thousands of motherboards manufactured and trying to enumerate which ones aren't usable is not something any volunteer project can do. -- Stephen J Smoogen.

The latest version of CentOS media is 7.6.1810 and you can find ISOs here: http://isoredirect.centos.org/centos/7/isos/x86_64/> "EXPERIMENTAL Support Enabled"This is part of an error output in 7.0.1406 for XFS support, see this for more details: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/7.0_release_notes/known-issues-storage You really ought to use a recent kernel, which you?d get in 7.6.1810.> Is it possible to > > 1: Get a specification of the computer characteristics on which Centos will run? > > 1a. Get the computer requirements, especially necescary disk space?The RHEL installation guide mentions this, and the same holds for CentOS. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/installation_guide/sect-installation-planning-disk-space-memory-x86> 2: Purchase a copy of a disk which is guaranteed to run a CentOS KDE system on the computer which I have described, and > and if so, from whom?Just install from a recent Image. ?
