Hi,

I don't know what it exactly stands for, probably it stands for index, I guess.

I was looking for some background information based on your directory names i.e. .../PX-8805/PX-8805 firmware updating.

If the image is an image of a device, such as a flash disk with multiple partitions, then the funky kpartx tool may be what you need. There is a bit of instruction on backreference.org.

Why are bothering to check it? Use qemu -hd1 imagename.img

Hi,

It seems a index or something like that.

^ you need to ask the people you got the image file from what it is and how to use it.

at this point we pretty much determined it is not a standard image backup.
