Your searching is no good. In general, just follow the links from the main page, it'll get you there quickest.

Oh, I assumed it had an advance search engine. the keyword VGA should have brought me to that page anyways.

Have you used Wikipedia? The search engine on Mediawiki is inversely proportionate to the awesomeness of the OMG Ponie theme. (Meaning it is very un-awesome.)

Anyways here's my lame one, it's gonna get better sooner or later:

One question, what ports do you write to to move the blinky cursor around?

XD your the first person out of 60 that found that out yeah i was sleepy and didnt know what to call it

and this is how you move the cursor

Code: Select all

/* Updates the hardware cursor: the little blinking line
*  on the screen under the last character pressed! */
void move_csr(void)
{
    unsigned temp;

    /* The equation for finding the index in a linear
    *  chunk of memory can be represented by:
    *  Index = [(y * width) + x] */
    temp = csr_y * 80 + csr_x;

    /* This sends a command to indicies 14 and 15 in the
    *  CRT Control Register of the VGA controller. These
    *  are the high and low bytes of the index that show
    *  where the hardware cursor is to be 'blinking'. To
    *  learn more, you should look up some VGA specific
    *  programming documents. A great start to graphics:
    *  http://www.brackeen.com/home/vga */
    outportb(0x3D4, 14);
    outportb(0x3D5, temp >> 8);
    outportb(0x3D4, 15);
    outportb(0x3D5, temp);
}

Just thought I'd add that while we were on the subject.

Well, a quick screenshot of Patlock 0.0.1 pre-pre-pre alpha

(50% is not implemented)

What to implement next: basic floppy reading/writing (FAT12 will be at Patlock 0.0.2), "about" section, suspend function (using APM), a spiral-like screensaver (a demo using mathematical coprocessor, now integrated into every CPU), reboot, poweroff and halt function and maybe more

No paging, no multitasking (for now). I like things simple and I'm a DOS fan

Here's a screenshot from my OS:

Wow.

That's all I have to say.

Posted: **Mon Jun 30, 2008 2:38 pm**

Wow! I'm majorly envious!

I agree with the others WOW, how long have you been coding it and any chance of a image to test on a real PC ?.

PS: How did you get the screen shots ?.

I'm working on this 'project' for 3 years in my freetime. Currently there's no testable CD image because i'm rewriting the guiserver and the gui library from C to C++

The screenshot is created by VMware.
