1.1       jdf         1: # How to install GRUB2 on NetBSD
                      2: 
                      3: This how-to explains the steps needed to install GRUB2 on an existing i386/AMD64
                      4: NetBSD-installation. The steps should work on a properly chroot'ed system too.
                      5: Tested on NetBSD 6.0 AMD64:
                      6: 
                      7: First of all, either download the package, using `pkgin install grub2`, or build 
                      8: it yourself from package sources (`/usr/pkgsrc/sysutils/grub2`).
                      9: 
                     10: 
                     11: After that, generate a GRUB configuration file, which tells GRUB the positions 
                     12: of the operating system(s). The following command will generate such a file, 
                     13: while adding your NetBSD system into it's list.
                     14: 
                     15:     # grub-mkconfig -o /grub/grub.cfg
                     16: 
                     17: Now, install GRUB into your hard drive's master boot record (MBR).
                     18: You have to know it's device name for this step (e.g. `/dev/rwd0a`).
1.2     ! jdf        19: Exchange `/dev/rwd0a` with your desired device name, then change `/dev/rXXXa` 
1.1       jdf        20: to `/dev/rwXXXd` to access the raw disk, as in the following example:
                     21: 
                     22:     Device name :   /dev/rwd0a
                     23:     Direct access : /dev/rwd0d
                     24: 
                     25: The appropriate `grub-install` command for this drive would be:
                     26: 
                     27:     # grub-install --no-floppy /dev/rwd0d
                     28: 
                     29: Hopefully, it should return : `Installation finished. No error reported.`
                     30: If it does so, simply reboot the system and you should be greeted by a nice
                     31: OS-selector.
                     32: If not, recheck your device names, if that doesn't fix it, search the web for 
                     33: the error message.
                     34: Even though there aren't that much resources about *GRUB on NetBSD*, you'll
                     35: find a lot of information at GNU/Linux-related sites which apply to this 
                     36: scenario as well.
