Actually such a shame that these videos aren't getting that many views, so much effort put into these. Even the older videos.

Awesome! I have learned a lot! Just one little optimization in your generate ISRS bash script: replace the sub-shell call "$(seq 0 255)" with bash's brace expansion "{0..255}". It's a way faster than calling a sub-shell. Thanks.

Once upon a time, there was a old nomad who walked this dangerous path of creating an OS, Terry Davis he was called.

What I don't get: earlier we called Interrupt 13h to communicate with the BIOS. Now Interrupt 13h seems to be an exception.
But how does the CPU now differentiate between BIOS calls and Exceptions?

[fundyjo]

will a graphical interface follow at some point? or is that not planned?

[fundyjo]

Is it actually true that most operating systems use Html for the interface (menu) so that's how I read it anyway...
