Think again about what booting means: You want to load the OS kernel into
Hi folks.
I'm trying to boot from a USB drive [1] (just the root filesystem is
important, not the kernel) on a machine that doesn't support USB
booting.
memory and start it. And you have to use the BIOS to do that.
So the kernel and any other file, which is used during the boot process has
to live on a media, which can be accessed by the BIOS.
Fortunately all stuff used during the boot process on Linux is installed
into the /boot directory. If the root partition is not accessable by the
BIOS, you usually put that directory on its own small partition ( 20 MB).
So the supported method would be: Resize the partition(s) on that DVR to
make space for a /boot partition and then run the normal installation.
As an alternative, it seems also be possible to run /boot from an existing
FAT partition. But I didn't test that, the installer of your distrbution
probably doesn't support that and I'am not sure, if the DVR uses FAT as
filesystem. Using an NTFS partition instaed is problematic,because the the
linux NTFS driver still lacks full wtite capability.
