FreeBSD in Grub
 

Hello,

I have two hard drives on my system. One has Debian and the other I just insstalled FreeBSD 7.1. My boot manager is Grub and I need to know how to create the entry for FreeBSD. I know the syntax is as shown below, but not sure about the "root" line. I've included the output from debian and fdisk.

Thanks,

ab

Solved:

I used this in Debian grub:

root (hd0,a)
kernel /boot/loader

I actually reinstalled FreeBSD and made sure that in the first fdisk screen, I set the FreeBSD line as bootable and am now able to boot into FreeBSD. Probably didn't originally set it as bootable.

Nothing has to be marked bootable in the partition table for GRUB or LILO to boot it.

Interesting. Why is "set bootable" option offered then?

Thanks,

The set bootable option is for the freebsd bootloader.

The set bootable option is a generic flag that other bootloaders can use or not. The DOS bootloader it was written for does use it.
