Red Hat Bugzilla – Bug 97410
Last modified: 2005-10-31 17:00:50 EST
Description of problem:
When installing on a "brand new setup" 2x IDE disks 60Mb each. Pentium 4
2.4Ghrtz 512Mb RAM
Version-Release number of selected component (if applicable):
Boot from CD, go thru install prompt up to entering root password..then system
...to continue with installation.
When exception occurred info appears and saved to Floppy. This is the text
that appears every time I try.
Traceback (most recent call last):

Have you performed the mediacheck on all CD media?
yep - twice already.
This error only occurs if there is a lack of memory or if there are read errors
from the installation device, in this case the CD. It might possibly happen if
there were errors from the hard drives but that is doubtful.
I would recommend trying a different CD drive if possible.
good news! the problem was corrupt memory chips.
after trying and failing to install 7 (yes seven!) different os's i had the
hardware bench tested and came to the shocking discovery that windows reads
only a portion of the memory chip (hence no memory errors). where redhat reads
the chip in a different way with a more intense integrity (hence all the
errors i got).
i am sure that 99% of the err's out there that look like this are related to
bad memory chips.
so this call can be closed. thanks for all your help.
Wow nice work!
I've been thinking of adding memtest86 (a memory test utility) to the boot CD so
people could test their systems.
