"Kon-Boot is an prototype piece of software which allows to change contents of a linux kernel on the fly (while booting). In the current compilation state it allows to log into a linux system as 'root' user without typing the correct password or to elevate privileges from current user to root. It was acctually started as silly project of mine, which was born from my never-ending memory problems :) Secondly it was mainly created for Ubuntu, later i have made few add-ons to cover some other linux distributions. Finally, please consider this is my first linux project so far :) Entire Kon-Boot was written in pure x86 assembly, using old grandpa-geezer TASM 4.0. [...]
All CD-ISO's are working in so called Floppy Emulation mode, which should be handled correctly by 100% of Bioses which support the El-Torito bootable CD format. The ISO images were created by some really basic utilitty created by me, however you can convert the floopy images to iso's by using programs like mkisofs etc. etc."
