  • Boot Dreambox from anything - no BIOS change needed

    so here we go:


    As usual - if you chose to do it - do it at your own risk :smile:


    NOTE - content of HDD/USB/CF will be erased and internal flash overwritten

    what's needed:
    1) a storage device
    2) Telnet & FTP client's
    3) nfidump
    -----------------------------------------------------------------------------------------------------------------------------------
    1) boot your dreambox and connect via telnet
    2) check if storage is mounted and umount it (USB, MC, HDD)


    a) print mount table: mount
    b) umount storage (anuthing pointing to your device /dev/sda* /dev/sdb* /dev/disk/...*):


    umount /mnt/HDD /mnt/usb ...


    3) create Linux partition via telnet:


    a) fdisk /dev/sda
    b) print ( p ) partition table and clear it ( d )
    c) create partitions (as many as you like) 1 needs to be LINUX EXT3 or 4 (this post is based on 2 partition example)
    d) write config ( w )
    e) format partitions: mkfs.ext3 /dev/sda1 ( and 2)


    4) mount formatted partitions:


    a) create mount points (if not exist) mkdir /mnt/sda1 (and 2)
    b) mount /dev/sda1 (and 2) /mnt/sda1 (and 2)


    5) copy your .nfi image to storage device (found copying to 2nd partition best) -- OpenATV 5.1 not working (/usr/bin/enigma2.sh: line 104: 2240 Segmentation fault) newnigma2 works perfectly


    6) extract .nfi:


    a) nfidump --overwrite /mnt/sda2/image.nfi /mnt/sda1


    7) update boot directory


    a) mount -o remount,rw /boot
    b) make a copy of boot directory (in case of rollback) cp -r /boot /mnt/sda2
    c) copy and overwrite the kernel cp /mnt/boot/vmlinux.gz /boot (or you can do it with FTP)
    d) update both autoexec*.bat to:


    only line with root=/dev/ needs updating:


    /boot/bootlogo-dm800se.elf.gz filename=/boot/bootlogo-dm800se.jpg
    /boot/vmlinux-3.2-dm800se.gz root=/dev/sda1 rootdelay=10 rw console=ttyS0,115200


    NOTE: root=/dev/sda1 - change this to: root=/dev/whatever is your device where you extracted image...


    8) reboot


    9) the result:
    769c08969dd97.jpg


    10) rollback


    a) mount -o remount,rw /boot
    b) cp -r /mnt/sda2/boot/* /boot


    Let me know if I missed anything...


    Cheers
