Sugarlabs, a fork of the huge failure that was the OLPC released an OS intended for USB installation so every aging and decrepit computer can have the ability to run an operating system and educational software.
It seems that Sugarlabs brought along some of the huge resources of FAIL at OLPC. It’s the only way I can explain how they missed the most obvious fact of obsolete hardware; If a decrepit computer even has a USB port, chances are huge that it’s bios is not going to allow you to boot from it.
At least they forked the development. You know how I love that.
