Did the patch work for you on reset? :)
I ran a couple of reset tests and they look okay.
S3-resume or an old style 286 resume, the f-segment must not be cleared.
Are you sure real HW does not reset chipset's BIOS mapping on S3? S3 resume can configure pam0 to map memory again (without copying BIOS) and it will see old memory content.
That is a good point. I don't know if real hardware does that. I'll see if I can run a test on my via chipset machine this weekend.
Should we go this route, it will require seabios changes to handle resume.
