Switching Video Mode

[TomMan]

Hi,

I am currently making my first OS, I need a way of switching the video mode to a nice high VESA resolution. Does anyone have any ideas?

Thanks in advance.

Yes, use the proper interrupt (0x13) to be able to access VESA functionality.

Ideas we do have, and they are worth a penny for a thousand.
The best one of them is the nice OSDev wiki, that is set for anyone to see right there http://wiki.osdev.org/Main_Page .
Inside, there is a section called Video - http://wiki.osdev.org/Category:Video , where many interesting things about graphics in general and video modes in particular can be found.
Just in case, VBE stands for VESA BIOS Extension.

If that is of no use, you would have to clarify your problem to figure out which of the remaining 999.9 ideas can be of use.

Thanks for those replies, I'll try them and see if I can get it working.
