Hello, I am developing my own operating system. It has its own filesystem, assembly compiler, c compiler, etc. I was wondering though how to access a CD drive using basic assembler at the BIOS level (no Linux or DOS interrupts!). I need to program the code to use the CD drive, but I already have IDE support. Thanks!

Why is it that questions on these message boards are either really easy or really difficult? In other words I have no fuxing idea...

lol, I think that I may be able to get a working prototype for IDE CD Drives, but not SCSI. I'll keep thinking about it.

nice, can you send me the coding for your OS? i'd love to see OS code, i know i could use lnix but i want a more basic os. I assume you also have a kernal and shell for the OS? and also what file system (FAT, FAT32, other partition) does it use and is it native?

i repeat metamorphic's statements. I would like to see the code too.

It uses my own filesystem. Yes I have a kernel and shell. Sorry but I'm not releasing any code until I have finished it. After that I will think about releasing it.

come on! Plllllllllleeeeeeeaaaaaseee! Im not going to critisise it or anything, i just want to see.

Sorry, it is STAYING closed source for now.

Hmmmm. I don't believe that it is truely an opensource OS then, if it is closed source during development :-)

For those of you who just can't wait, see the rather valiant attempts of one of our TPUers of old, DrDevil.
http://gaztek.sourceforge.net/ and go to the "GazOS" and "OSDev" sections. It features many of the things sord has talked about, like its own FS, a full kernel and a basic shell.

thanks gian
