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.
Hi, It's me again
Okay so I got I nice litte kernel, loads, prints a litle bit of information and then it waits for keyboard input. But thats is the problem, it WAITS for keyboard input! I don't want it to wait... I want to have a INT fired when the user pressed a key, but I don't know how I'm in pMode, wrtting in C and I don't know what to setup.
I tried looking at the Linux sources but the pc_keyb.c uses soo much other functions outside that I can't undersant a thing . So I request your help ;D
Humm okay, I think I'll need to know: what is an 'IDT' ? I know what the PIC is but I don't know how to access it.
Oh and Tom, I'm using your bootsector -- Or I think it's yours... well anyways, not your kernel. (Bootsector is said to come from FritzOS 0.6 -- Oh wait! there's your name, Tom, in the copyright so I think it yours. )

The Interrupt Descriptor Table is the the protected mode equivalent of the Interrupt Vector Table (IVT); it holds a list of the interrupt vectors, that is, the addresses of an interrupt handlers for each interrupt number. The SIGOPS Roll-Your-Own OS tutorial has a good page on the subject. A messageboard search on "Interrupt Descriptor Table" also brings up a fair amount of useful info.

It's OK to feel like that when you are one, esp. since these are issues you'd almost never encounter except in OS design. You're actually doing better than most do starting out; it took me years to get where you are. Don't rush things, and it will come in time.
I'm in pMode, wrtting in C and I don't know what to setup.
