When something that previously worked starts giving you problems it can be

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 ?

DVD used: TDK DVD+RW

DVD Recorder: NEC ND-2510A with firmware 2.18.


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.

[Dennis McLeod]

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 tracked the problem to the latest firmware of my DVD recorder. I
reinstalled the previous version and it looks like everything is OK.

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.

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.

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.

That should help determine if the problem is a bad DVD image when burned

Not passing an md5sum/sha1sum can be caused by many things, some of

In my case the sha1sum/md5sum tests are succeeding.


Well ... one of them is succeeding (the one on the file before you

burned ISO to an embedded md5sum that was added at build time.

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

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.

I installed from the CentOS 5.1 x86 DVD image without a problem, so maybe

It was some time ago, and don't recall all details. I thought it was a

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.

Do you mean use a command or something?

By heart, my system is:

Motherboard: ASUS CUV-4XE with the latest BIOS update.


My system passes memtest86+ 1.70 default tests.


SL 5.0 x86 and CentOS 5.0 x86 installation DVDs work OK.

SL 5.1 x86 and CentOS 5.1 x86 installation DVDs fail to install.

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.

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.

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

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.

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?
