Hi to all.

I've got a little problem with an OS i'm programming with some friends. When I emulate it on Bochs/VmWare, I get no errors. I tried it on real hardware (my CPU is AMD Athlon XP), and when I press the first key, all the previous characters are canceled, but I can continue typing the command and the shell recognizes it. When I press Enter, the prompt is restored normally.

I think it's a problem of video memory management, but I don't know how to find it.

[Sorry for my english, but i'm italian ]

Thanks for any help

Could you give some code? It's hard to say what is the source of the error, without having any code.

probably a problem in your gets command i had that kinda problem,
1. try sending it the pointer to a buffer NOT allocated on the stack(global)
2.make sure your advancing the curor

If you want to see some code:

cvs -d:pserver:[email protected]/cvs/dreamos co dreamos

Well, actually it has to be reviewed, we can code it better Unfortunately for you, most of comments are in Italian, if you want some explanation, please ask me
