Default dualboot configuration with linux(centOS)/grub legacy
hi there
I reccently yesterday tried out PcBSD the first time and first I have to say thank you a lot!
In the last 10 years I never was impressed about a new distribution of any os ive seen like pcbsd.

now I tried to make a dualboot on the same disk with centOS(I need it actually for learning all the rpm based linux distribution stuff). first I had problems when configure my disk that it doesnt let the not partitioned space for free but this is another issue.
so I took the simple way of configuration at the and just create parition and click on it to install. because I have the first primary partition for linux fs and the second for swap, the pcbsd get the third.some how I couldnt add a swap partition bigger than 999mb as the 4th device so I decided wait with that

the installation went fine ive got no erros

this is my disklabel
Code:
       sde1                     Boot                     Primary             Linux ext3                                                        83886,08              *
        sde2                                              Primary             Linux Swap / Solaris                                               2147,49              *
                                                          Pri/Log              Freier Bereich                                                        0,02              *
        sde3                                              Primary             FreeBSD                                                           71303,15              *
                                                          Pri/Log              Freier Bereich                                                     2704,12              *
and this here is my grub.conf (I use grub legacy)

Code:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,0)
#          kernel /boot/vmlinuz-version ro root=/dev/sde1
#          initrd /boot/initrd-[generic-]version.img
#boot=/dev/sde

Hi, people!
I had an PC-BSD 9.0 64 bit installation in dual-boot with CentOS 6.2 rolling-relase 64 bit in my notebook.
I was using the GAG boot-manager to start PC-BSD or CentOS, as I like. I have not changed at all, the CentOS GRUB file.
I had only put the CentOS GRUB into the CentOS root-Partition. After this, I have installed PC-BSD 9.0 64 bit and after that, I have installed GAG into MBR.
And all works good, without any problem.
