I'm trying to get a backup of the bios of my desktop computer, but it fails with this message:
# flashrom -V -p internal -r bios.rom flashrom v0.9.9-91-g0bfa819 on Linux 4.13.0-0.bpo.1-amd64 (x86_64) flashrom is free software, get the source code at https://flashrom.org

I tried with flashrom "v0.9.9-r1954" from debian/stable as well as the latest version from the git repository. Both gave the same results.
Here are the results of the recommended steps fom https://flashrom.org/FAQ :
- The page "https://www.flashrom.org/Supported_hardware" lists ICH7/ICH7R as supported, but this does not seem to be the case for me.
The user manual of the motherboard is available here: http://www.produktinfo.conrad.com/datenblaetter/850000-874999/871892-an-01-e... - The manual does also not show any jumpers that protect against bios updates.
- The bios setting "Super BIOS Protect" is disabled.
Do you have any suggestions how to proceed ?
Cheers,
Alois
