Do you know where I can find his tutorial? Also, do i have to make my own filesystem, or can i use an existing one like FAT12 or something?

By the way, whats an IDT?

The link for my tutorials (I should be updating with the next few parts next week), http://www.invalidsoftware.net/os/. I hope you find it usefull.

I've only covered runtime support for global / static classes so far.

Hmm...did a mod delete my posts? ??? ??? ???

A IDT is the Interrupt Descriptor Table. Links:

Info from me:
Simply Put: It lets you control what happens in the computer. Lets say, your OS is busy letting this or that app run. The IDT lets a interrupt occur that tells your OS that it's time for the other app to run...and when your OS is busy processing, and the user presses a key, it can hold the key, wait for this and that, and then let the key happening occur.

Etc.

Fat12:

Info from me:
Fat12 is the way the computer stores information on the media. There are many better FSs ( file systems ) out there, but Fat12 is very simple and easy to program, learn from, etc. Fat16, used by old windows, Fat32, Used by Win98, VFAT, used by WinME.
