Re: Find VBE mode - The grub way
Hello and welcome.
In the past i get the modelist and the modespecific information from the bios and i get the EDID from the monitor, but i never used GRUB. So i want to know, if it is also possible to choose a refreschrate controlled mode with GRUB, if we found a vbe3 bios for to use a resolution of 1024x768 with 100hz refreshrate together with a 19" CRT-monitor with 96 khz capacity for example?

@muazzam - Welcome to the community.
I appreciate what you're doing by informing people of this feture (it should probably go on the wiki), but you should know that all this function does is enumerate the modes provided by VBE by calling the relevant BIOS calls (same as an OS would do when selecting a video mode).
The mode numbers listed by this command will usually differ between machines, and shouldn't be hard-coded into a kernel. (They are, howerver, suitable for passing to the linux afaik).

Kernel Development, It's the brain surgery of programming.
