[flashrom] Re: Your flash chip is in an unknown state

[Mike Banon]

Reposting your messages to a flashrom mailing list. Are you sure that a
contact of a clip - with a chip - is good enough? If a chip is hanging in
the air and its legs aren't mounted to the motherboard, the legs are prone
to a tiny bending and the contact is less certain. Do you have a DIP8 to
SOIC8 adapter - to plug this chip directly to a programmer without a test
clip?
