I am developing a kernel for an operating system. In order to execute it, I've decided to use GRUB. Currently, I have a script attached to GRUB's stage1, stage2, a pad file and the kernel itself together which makes it bootable. The only problem is that when I run it, you have to let GRUB know where the kernel is and how big it is manually and then boot it, like this:
kernel 200+KERNELSIZE boot
KERNELSIZE is the size of the kernel in blocks. This is fine and alright for a start, but is it possible to get these values in the binary and make GRUB boot the kernel automatically? Any suggestions on how to accomplish that?
I would imagine you could just make your own menu.lst conf file, load that at the grub shell with "configfile /path/to/menu.lst" and then do "setup (hd0)" replacing values as needed. I'm just guessing though.. no telling what the differences are on your custom setup.
