Post subject: | Setting the VBE video modes using GRUB 2 |
I'm coding a simple toy OS in Assembly and C. I'm trying to get a VBE video mode set by GRUB 2, but I simply don't know how. The OS is running in 32-bit protected mode, but I'm interested in having a hi-res video mode. The kernel is running above 1 MB sadly, so I can't just switch to real mode and back without copying code into the <1MB mark (which I can't figure out how). I haven't implemented userland yet, so vm86 won't work. How do I set a VBE video mode using GRUB 2? |

You could do worse than use Google, which would give you this link (amongst many): https://wiki.archlinux.org/index.php/GR ... resolution |
