could you join us on IRC in #flashrom at irc.freenode.net so we can
debug and fix this problem? Email is a bit slow and IRC is so much faster.

Ouch. A laptop. Laptops are unsupported because so many things can go
wrong. Anyway, we're determined to fix this and we're pretty good at that.

Looks like a boot block lock. Can fix.

First of all, don't panic. There's a good chance we can recover.
First step: Copy your good backup to another external medium. Too many
people destroyed their backups by accident.
Second step: Run
flashrom -c SST25VF016B -V
(all commands as root)
and mail the output to flashrom at flashrom.org (just hit reply-all in your
mailer). Then join IRC and chat with us. If you don't have an IRC
client, you can use the webchat:
We may need your backup BIOS image later, but please don't send it to
the list for now.
