I did miss that line in the first mail. Your BIOS traps the access to
that register and reverts it in SMM so that the general write
protection of the flash chip remains enabled. See also the mail titled
"success hacking DELL Dimension 4100" with the same underlying problem.
Sadly the exact hack was not posted (yet), you may wanna ping Bertho to
send his solution.

While that's not the problem, you need to take that range into account
to. It is probably the boot sector.

Kind regards/Mit freundlichen Grüßen, Stefan Tauner
