The failures were slightly different. My first attempt went as follows:
1. Downloaded and decompressed the latest 3.0 ivi-XYZ.raw.bz2 into a
bootable USB memory stick with Gparted on it. NOT overwriting the entire
stick, but in the filesystem on it.
This resulted in a ivi-XYZ.raw being next to the Gparted.
2. Stuck this bootable stick into the machine. Set it to boot from the
stick (which contained Gparted and a decent micro boot environment)
3. In the shell of this environment, did a: dd if= ivi-XYZ.raw of=/dev/sda
.... in other words, wrote the downloaded raw data over the hard drive
4. Used the refresh command within Gparted. This did two things: it saw
two new partitions created on the disk, and complained that the
backup MBR wasn't properly set to the end of the partition. It asked if
I wanted to fix it.
5. I let Gparted fix the backup MBR, reset the box, and attempted to boot
from disk.
Result: Received a "No bootable device" error.
Attempt #2 went as follows:
1. Downloaded and installed bmaptool
2. Since I already had ivi-XYZ.raw.bz2 downloaded, I just tried using it to
completely overwrite a different stick.
3. bmaptool complained about a missing --nobmap option, so I added it.
4. Tried to boot off of the stick that this command created.
Result: A black screen on the device. No error about a non-bootable device.
In the successful attempt, I simply downloaded the .map file from the
website, and removed the --nobmap option. This worked.
It may be that I did something very stupid, but I don't see anything
immediately wrong with my first two attempts, except that they didn't end
right.
Thanks much. I'll be writing something new in a bit on this list as well.
