The thing I was trying to clear up is that the hd(0,0) is only used by Grub, and not the kernel. It it only used after the menu is loaded. For example, if you did not have a /boot partition, you might have kernel /boot/vmlinuz instead of just kernel vmlinuz The hd(0,0) is only used to tell Grub the base of the path. You can also have different menu entries that use different base partitions. For example, you could have another distribution installed with the boot partition being partition 5 instead of 1. You would use root hd(0,4) as the base when pointing to those kernels. But neither specifies where the grub.conf file will be located. This is set when you install Grub. The physical location of stage 1.5 is written in the boot sector when you install Grub. (Usual in the mbr.) Stage 1.5 can then read the file system to find the menu. The stage 1.5 version is determined by the file system, and it is given the partition and path to the config file as part of the Grub installation process. > But, given the lack of _good_ info on how grub really works, (IMO docs should > be complete enough that the function could be re-written based entirely on > the documentation available) such an obviously erroneous conclusion could > easily be drawn. > Yes, the info page is hard to navigate. Unless you know what you are looking for, you are going to have a hard time finding it. (You can have a hard time even if you do know what you are looking for.) About the only thing you can say for it is that it is better then the man page. I have often wished for the writing skills to re-write it. But that is beyond me. I do have some bits rattling around in my head. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
