OK... Here we go m8.
In this example I use a 320 gb usb hdd, Latest PGI image in the flash and latest PKT image (e2).
connect your usb hdd to the receiver
Power on with the dgs image and wait till you get a picture
download a usb.tar.gz version of your desired e2 image into your pc (desktop for example)
from your pc telnet to your box (with your password/login (root/relook))
then type:
1) umount /dev/sda1
2) fdisk /dev/sda
3) type p and enter
look for the name of your existing partition (sda1 for instance)
then type d and enter
delete the existing partition(s) one by one
4) Create 2 partition on the HDD
n for new partition
w for saving the partition
in my case, I created almost 2 equal partitions (one for the e2 image and another for pgi) like this:
(remember its for my 320gb hdd so you need to choose your own deppending on the capacity of your hdd).
type n then enter
choose p then enter
type 1 then enter
Now choose half of the capacity of your usb hdd, in my case:
1 - 16000 then enter (there are spaces between "1" and "16000" and "-" and "16000")
type 16000 and enter again
type n again
type p and enter
type 2 and enter
enter
and enter again
now type w to write the changes
4) Format each partition
to format sda1 partition type:
mkfs.ext2 -I 128 /dev/sda1 -L ext2
enter
to format sda2 partition type:
mkfs.ext2 /dev/sda2 -L ext2
enter
5) mount /dev/sda1 /mnt/usb
with FTP copy the image you want myimage1.tar.gz to /mnt/usb
TELNET
cd /mnt/usb
tar -vzxf myimage1.tar.gz
sync
rm myimage1.tar.gz
disconnect ftp
cd /
umount /dev/sda1
Now reboot your box and as soon as you see "BOOT" on the front display press and hold number 2 key on your remote for 8-10 seconds and you should be able to boot from e2 on your usb hdd
This way you can record and timeshift with both pgi and pkt images on one hdd
(if decided to use the pkt image you must remember to mount the sda1 through its mount manager (blue button on remote)
Good luck
