See title.
I've looked around, and I see that for Insyde BIOS' it was discovered that BIOSWE can be kept unlocked at boot in order to later flash with software.
I'm asking in order to play around with multiple BIOS updates, and I get sick of constantly opening the laptop each time. If we can do a hardware flash that runs our code, what is stopping us from stubbing the lock mechanism that disallows writes? Is it not stored in the BIOS?
I don't have the ASM experience to do it myself currently, but has anyone else had such luck?
In particular, I'm curious about post-xx20 ThinkPad machines. I have a bunch of machines that need BIOS flashes, but I don't want to have to dismantle it after the Intel ME update comes out.
