It's good to that.  I've just tried that seven times (three different 
flashdrives 'dd' using different USB ports, then created one CD) and the 
media test failed each time. I wish those downloads listed cksums/md5sums.

I checked the BIOS firmware just a couple days ago, the latest version 
was already installed.  So the laptop out of the carton was fine.

It's good to have all this info  together in one  email.

On the other hand, people should know the Minimal really sucks:


* No dual-boot set up.  It just blithely wiped out the ability to boot 
up Windows.  At some point I'm going to have to recover my Windows 
install because of this install.  Every Linux install I've ever done-- 
out of hundreds of them and going back to 1992-- has gracefully and 
easily set up a dual-boot.  The README should at minimum mention that. 
Better yet, the install's name should be given "Non-dual-boot.iso".

* The resultant OS was text only.  I.e., it wouldn't run init 5... 
trying to do so would cause to hang.

* Maybe the above problem was due to bad coding somewhere-- the entire 
OS horked a couple times... then I finally saw error code saying, 
"kernel panic".  I haven't gotten one of those in decades.

Geez, what a terrible ISO distro!
