Description Peter D 2012-03-19 07:34:07 CET
When trying to install from a DVD things don't get very far.  

It loaded the kernel then got as far as a screen that said; 

"Welcome to Mageia release2, Mar 12 2012 20:53:07
  Please answer...
 I can't access a Mageia Installation disk in
 your CDROM drive (ASUS CRW-5232AS).
 Retry?
  Yes  No  Back
<Alt-F1> for here, <Alt-F3> to see the logs, <Alt-F4> for kernel msg


Using a DVD of Mageia2 beta2 i586.

Hi Peter,

Can you confirm that after burning the disc, you also checked the integrity of the disc? Also, can you confirm the checksum of the .iso file you downloaded matches the one on our website?

(I used the same ISO without issues, though admittedly from a USB stick instead of a DVD)
Comment 2 Dave Hodgins 2012-03-19 19:20:26 CET
My wag is that this will be a duplicate of bug 4997, but
in the installer, I'm not sure how to force the module
pata_amd to load before pata_acpi.

Hmmm, it fails on the computer with a PATA DVD drive but not on the computer with a SATA DVD driver.  

The command 
rawread /dev/sr1 | cmp Mageia-2-beta2-i586-DVD.iso -
checks out ok on the machine that has the iso file on it, and 
rawread /dev/sr1 | nice md5sum
gets the same number on both machines, BUT that is a different 
number from the published md5.  

rawread looks like this... 

$[psd@live] cat rawread
#!/bin/sh

# script taken from "Coasterless CD Burning" by Steve Litt
# <http://www.troubleshooters.com/linux/coasterless.htm>

# Typical use;
#       rawread /dev/cdrom | nice md5sum
# or
#       rawread /dev/cdrom > my.iso
# or
#       rawread /dev/sr1 | cmp [file_name] -

PATH=/opt/schily/bin:$PATH

device=$1

blocksize=`isoinfo -d -i $device | grep "^Logical block size is:" | cut -d " " -f 5`
if test "$blocksize" = ""; then
        echo catdevice FATAL ERROR: Blank blocksize >&2
        exit
fi

blockcount=`isoinfo -d -i $device | grep "^Volume size is:" | cut -d " " -f 4`
if test "$blockcount" = ""; then
        echo catdevice FATAL ERROR: Blank blockcount >&2
        exit
fi

# DOESN'T WORK blockcount= $(( "$blockcount" + 166 ))

# original
# command="dd if=$device bs=$blocksize count=$blockcount conv=notrunc,noerror"
# BitTwister
  command="readcd -v dev=$device f=- sectors=0-$blockcount"

echo "$command" >&2
$command

I found that the md5sum returned by the "Coasterless" script never matched the published md5sum.  If I ran the script on the downloaded ISO, I got a different result which DID match.  I have no idea why.  Seems much the same for you.

Hi,

This bug was filed against cauldron, but we do not have cauldron at the moment.

Please report whether this bug is still valid for Mageia 2.

Thanks :)

Cheers,
marja

No problem for me nowadays.  The only problem is a different one: where do I find the mountpoint?  It seems to be somewhere in /run/doug/

closing then, feel free to reopen
