Dear All,

I have an ISO fromat via dd from an old scsi unix:
dd if=/dev/hdc of=./all_files.iso
I have the following information from my iso:
parted ./all_of_disk.iso print

I think it's sysv unix. How can I detedct its' arch via qemu?

--Best regards
The qemu toolset has no functions that could do this.

Trying to treat it like a harddisk (parted, fdisk etc.) is not useful either.

Try to unpack the iso with e.g. 7-zip (or just loop mount it).

Then use the file command on various program files inside.

Another technique would be to use ISO specific tools to examine the metadata of the ISO image, there may be useful info there.
