Question about which tools to use, bugs, the best way to implement a function, etc should go here. Don't forget to see if your question is answered in the wiki first! When in doubt post here.

It's on github, licensed under the NCSA/UIUC license (which is basically BSD with an advertising clause).

@klange Impressive work, but there is a problem: you seem to use rme in order to change the vbe mode. This will work on many emulators but real hardware. Usually the BIOS uses some instructions not supported by that virtual machine. A long of time ago I tried to add the support of the newest and some 32bit instructions used but It wasn't very useful since that solution worked only on some computers. You may want to consider this point ;)

edit: is that a cow the one shaped with characters in the colourful console? XD

I'm aware of this (my laptop uses unimplemented instructions). Proper VBE setup is my current work-in-progress. There's a more complete x86 emulation library out there that I was going to port...

Hm, is any of you working on a usual multitasking, long-mode, smp kernel? There are tons of protected-mode, single cpu kernels out there, but I haven't really seen one of the former (except Pedigree maybe).

Except for long-mode, yes.

Define "usual". My kernel is multitasking, long-mode only and will support smp soon (I designed it with smp in mind from the begining). But I would not say it's a usual kernel.

I am. I'm converting my old 32bit, single core (well it was SMP with a BKL), Posix kernel to an long-mode, SMP, Posix kernel. Pretty much a full redesign going from single core to SMP.

Mine's pretty usual I think except that the VMM is a process.

Yes. It's a text dump generated by a Python script.

This is how PointerOS looks like at the moment.
Only some CPUID test code.

Hi all,

its been a very long time since i was properly involved in OSdev, but just before xmas i dusted off my source code and re-evaluated where my own OS is going. I have changed the name of my OS but this is not reflected in my screenshot, and i am aiming to create a preemptive multitasking OS which is similar in behaviour to the BBC BASIC interpreter built into the BBC Micro (a rather famous oldschool computer in the UK) except with extentions for multitasking.

The entire system as much as possible shall be built in my own derivative of the BBC BASIC language. I have recently got the interpreter running properly in a multitasking environment, with console input and output (optional switchable consoles per process) this is the result of launching a test BBC BASIC program as the init process...

For the new os name, i am thinking 'retro rocket', retro being oldschool etc. Thoughts? :-)

I couldn't get a screenie, but here is a Bochs console dump
Press F12 for boot menu.
