For programmer it would probably be simplest to use another mainboard which is compatible with flashrom.
Can we remove BIOS with the machine turned on? Meaning: We boot with the good one, we remove it, we insert the second machine chip and flash it. Does it work?
Yes. This link has pictures of the pushpin method. It works very well for PLCC, which are pictured.

The downside is that it will take a long time to try a new design, since you will have to boot the machine to Linux, flash the new design, and reboot. Having another machine that is already up will save a lot of time.
About the compatibility, I have a motherboard with a socket that has a award BIOS, is the chip/socket the same for AMI? Are they compatible?
Any BIOS vendor could use any type of chip. Unfortunately, that won't help you figure it out.
