Hi everyone, my first post here

Font fail (or so I assume… yet to fix it) changing to 90x60 text mode:


Currently my OS is more or less an amalgamation of code from various tutorials, some of which I don't even understand (definitely not happy about that bit), so my plan is to get it all running using tutorials and examples if need be, then read/rewrite big chunks of it until I know why it works

You're using the 8x16-font instead of the 8x8-font, which is why it got cut off. This might be useful.

I tried some stuff with pixels in real mode. It should have printed just 3 pixels with different colors, but it did a lot more......

I think it actually looks quite pretty.

Thanks, I got it working shortly after doing that post. Also, the line length was wrong—I'd hard-coded it as 80 and forgot to change it when changing modes.

This is a text-mode transcript of an attempt to print the sizes of various data types.

I fixed the problem (my buffer was being cleared incorrectly), but this was the first time I've had my OS vomit in any kind of visible way. I found it strangely cheering...

Nothing special,

only a bug in echo, but nice effect

And the bug is, if you enter "reverse", it will display all words in reverse order? That doesn't sound like a bug to me

Actually, it copies all the words after "reverse" in the right order, and add "reverse", and copies all words before "reverse" in the reversed order

I think it's just that his vararg implementation takes arguments the wrong way round... (was hoping something to do with postfix notation of the "reverse" operator, but I don't think it's that ).

Not entirely sure what I did but something went very wrong...

He just wants to tell you how he's feeling.
