I already tried to reduce the rw area, and just keep 0xe0 -> 0xef. But obviously it doesn't work the device model needs to write on this frame 0xf1. I still don't figure out why.



The rombios write on this page because of this flags s3_resume_flag
(rombios.c:98883). I don't know if it's a good reason to set the
rombios as rw. However it's bad to set the first 2 pages of the rombios
as rw just because of that.
Any suggestions ?
