I’m considering buying the Framework Laptop, but I’d love to know if it’s possible to boot into CSM mode - the Compatibility Support Module mode which mimics the boot process of pre-UEFI BIOSes. (Also known as “legacy boot” in some cases.)
I took a look at the BIOS Guide and couldn’t see an option for it, but I’m also aware that there are apparently options that can’t currently be accessed, and looking through the extracted IFR file (as extracted by following the instructions in that post), I can see that the Boot_Hidden form set contains a Boot Type option which can be set to one of Dual Boot Type, Legacy Boot Type or UEFI Boot Type. This is exactly the option I’m looking for, but of course, it’s in the hidden menus so I wouldn’t be able to get to it easily.
Is there any means of getting to it so that I can enable CSM booting?
