Installing Mondo Rescue on Clark Connect.

Packages required:-
These worked for me on Clark Connect version 4.3
gzip is installed by default on my system.
mindi-1.2.0-2.rhel4.i586.rpm
mindi-busybox-1.2.2-2.rhel4.i586.rpm
mondo-2.2.0-2.rhel4.i586.rpm

You need to connect in using ssh and install these packages.
dvd+rw-tools
which
afio
mkisofs

apt-get install dvd+rw-tools which afio mkisofs

These versions threw errors after upgrading to them.
mindi-2.0.4-1.rhel4.i386.rpm
mindi-busybox-1.7.3-1.rhel4.i386.rpm
mondo-2.2.7-1.rhel4.i386.rpm

Complaints about mindi errors with /dev/md2
The problem was solved by removing references to LABEL in /etc/fstab
The system involved was using software raid1 but the swap partitions (one per drive) had been created as
LABEL=SWAP-sda2 swap swap defaults 0 0
LABEL=SWAP-sdb2 swap swap defaults 0 0
The answer was to change them to /dev/sda2 and /dev/sdb2 respectivly, removing the reference to LABEL.
These latest versions of mondo mindi and mindi-busybox are now working fine.

PC Hell: How to Fix Problem When Windows Updates Download But Won't Install

PC Hell: How to Fix Problem When Windows Updates Download But Won't Install: "How to Fix Problem When
Windows Updates Download But Won't Install"

This page (at PC Hell) has information on how to fix the problem of windows automatic updates download but fail to install.

I had to keep going to the last section where you delete the downloaded updates and associated cache to get mine going again.
My mistake was to expect XP Service Pack 3 to uninstall cleanly. I even took care not to install IE 7, but uninstalling SP 3 just killed automatic updates.

Thankfully I found this page and it has (almost) fixed everything.

The only update that seems to refuse to install now is the "Windows Genuine Advantage Notification (KB905474)".
As long as that's the only failing update I really don't have a problem. The OS came from Dell with the PC, so being genuine isn't an issue. Just as long as the update servers don't have a problem with my XP installation I'm happy.
If I get really bored some day, or some problem related to WGAN arises I may investigate further.
