That's as close as I could get it in the time I had available before heading out of town for Christmas. I'll probably work on it some more when I get back...

One thing I have to ask though, on that first screeny you posted, is that a progress bar, or just a pretty graphic?

Yes that is a text mode progress bar that adds some blocks after some OS loading events.

Thats one thing I've always wondered how to do: how do you exactly calculate the timings/percentages etc? Care to share a bit of code with us? Loving it! Very well done =D>

That is a closed source OS but i can tell you how
i have printed a character after some OS events like "Printf(".");"

Hello,
This is PointerOS (again) a few minutes ago
It shows some boot information and a improved CPUID

I wrote one a while ago which I have since lost. I'll go through how it worked.

There was a struct that looked a little like this:

Code:

struct splash {
        const char* action;
        init_function func;
};

then a function, int splash(struct splash* actions), which you would call something like this:

Code:

struct splash actions[] = {
        { "Load Global Descriptor Table", gdt_init },
        { "Load Interrupt Descriptor Table", idt_init },
        { "Enable Paging", paging_init },
        { NULL, NULL, }
};

splash(actions);

It would count the number of actions in the list, figure out the current percentage based on which item it was doing and how many actions were left, then it would draw a bar in roughly the middle of the screen, with the percentage drawn in the middle, and write the string "action" underneath the bar. I think I also had a "struct splash_screen" that described how to draw the splash screen itself but I don't remember.

I'm going to write this again, it was fun, but I never got to test it.

Suddenly it all makes sense. Thank you. I will get started on this as soon as I have done some debugging (which may take a while) and finished the rewrite of the shell into the message loop structure (should have done that first I guess. bad design considerations cost a lot of time :S). Thanks Synon xD
