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

and this here is my grub.conf (I use grub legacy)


# 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.

#          initrd /boot/initrd-[generic-]version.img

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.
