Hi, I had downloaded CentOS 5.1 x86 DVD image, and although it passed sha1sum or md5sum test and I burned it verifying it, installation failed.
Also if I recall correctly, when I tested the medium during install, it failed although as I said the media was verified.
==> The same things happen with Scientific Linux 5.1 x86 installation DVD, so perhaps it is a Red Hat EL 5.1 x86 DVD issue?

CentOS 5.0 x86 and Scientific Linux 5.0 x86 installation DVD images do not exhibit this problem.

I installed from the CentOS 5.1 x86 DVD image without a problem, so maybe it is a post-install problem. 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.

If neither worked, it doesn't sound like a download issue (agreeing with you that it verified.) What exactly 'didn't work'?

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.

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.

Here's an issue with Kernel Panics that Ive had. It was not due to bad media etc.. As it turned out it was the bios settings. Either the Bios had to be set to """Default Settings""" or ""APCI"" had to be turned off. Also overclocked processors will cause this also and bad ram.
Like Johnny said MD5sum besed on it passing is really dependent on the media you burn the image to. There is really crappy media out there. Stick to a good known brand
You can pass no apci to the kernel at install time and try that also.

Legacy USB Support is Supported indeed. As in the USB 1.0 Specification. Also burning the disc to fast will cause it also. Try burning the disc at "4x". I know that will take a while.

My usual advice - for those not using VMWare - is: Once you have a valid ISO image (md5sum/sha1sum passed), burn it to DVD. Attempt to mount the freshly burnt DVD. If the mount fails the DVD burn was bad. If the mount succeeds, loop mount the ISO image and perform a diff -r

Well ... one of them is succeeding (the one on the file before you start) and the other is not. The internal media check is comparing the burned ISO to an embedded md5sum that was added at build time.

This has to be a hardware specific issue as two distros fail to install. Perhaps if you were to post your hardware specs, someone may spot an obvious problem.

ok, I have read all your follow up messages in this thread and you have'nt actually mentioned how and when the install failed and with that message.
So rather than everyone going round and round in circles trying to work out wtf is going on, why dont you just tell ?
exactly how are you doing the install ? what sort of vmware do you have setup ? what kind of machine ? using a script / kickstart ? why are you using a physical media when vmware can directly install from iso. etc. And dont forget to mention how the install fails.

Well, I dont really care what he wants to test or not. But if something broke, its reasonable to expect the user to provide some details about what broke and how. Even if its just a question of relaying an error message seen on the screen.
In the absence of any such info ( as a wise man once said ) - it didnt happen.

Well, that would depend on how Ioannis worked out his install had failed. Besides, Function keys dont work well when you are using serial console.

I tracked the problem to the latest firmware of my DVD recorder. I reinstalled the previous version and it looks like everything is OK.
OS: Ubuntu 7.10 x86.
Unfortunately I still got the problem.
I downloaded the CentOS 5.1 x86 DVD image, it passed the md5sum/sha1sum tests, I burned it with nerolinux with verification, I copied all the contents of the burned DVD to a hard disk directory successfuly, it passed the media test during installation and then I got the screenshot attached error message.
vmware version: 6.03 with IDE virtual hard disk.
I just did a minimal network install this morning. I downloaded the 7 meg iso for the boot cd, and used Stanford.edu for the os source. It took me about an hour to get a minimal machine booted. I ran yum update and installed httpd after that. I don't think I'll download the CD's or the DVD anymore...(Unless I'm going somewhere remote...) If this box is able to get to http or FTP, I'd try that. Yum install whatever else you need after you get booted.... I just needed a quick box for a test, and didn't want to download CD's (no DVD drive)

I faced similar problems when I tried to install CentOS 5.1/Scientific Linux 5.1 x86 from their DVDs in my natural machine (the firmware was 2.18 and it has been a stable one which I have been using for a long time, it is the original stock firmware, not some hacked one)/
CentOS 5.0 x86 and Scientific Linux 5.0 x86 DVDs were installing OK.
Now I am using the CentOS 5.1 x86 DVD image directly under VMware to perform the installation and will report in another message what will happen.
It was a hardware problem with my DVD recorder. I got a new one and now everything works OK.

vmware will let you use an ISO file as a CD-Rom or DVD-Rom drive, try pointing your vmware instance at the iso file, and bypass the physical DVD drive in your machine completely. do you still get that error ?

Another possibility is a hardware related issue. In another thread in the past, Johnny suggested adding 300K of pad to the ISO image. I use cd-record. I did some testing. I just yesterday found the floppy that contains my notes on the results. I will be posting a [SOLVED] to that thread (I'll find it later) that discusses this.
In a nutshell: some drives have trouble reading the tail end of the recording on the media. I tested older ones (sounds like you might have one) and a newer Lite-on. Some worked fine, others failed.
Using dd to append 300K of zeros (from /dev/zero) may fix you issue if the problem is this one. Symptoms are erratic because the install continues until it receives notification of the read error, which is deferred by some indeterminate time.

Whats here below is with the CD Install Discs. These are the sames issues in my opinion.
Just to my curiosity in doing a write up for something centos related. This is what happened; Downloaded centos 5.1 Disc used "Infra View" under Windows to burn the image. When booting with the just burned image it failed not finding vmlinuz. When the disc is burned with cdrtools under X CD Roast the disc did not fail when used to boot the install.
Infra View was obtained from sorceforge and installed under Windows XP Home Edition. This was on a Compact Presario Desktop. Both discs were burned at a rate of 4x.
