GD 2W10 Posted April 23, 2023 Share Posted April 23, 2023 Hi, Is there a way to boot BIOS/CSM on a UEFI Class 3 device such as flashing it with SeaBIOS or an app that emulates CSM/BIOS? And no, using a VM is not possible. Link to comment Share on other sites More sharing options...
jaclaz Posted April 23, 2023 Share Posted April 23, 2023 Short answer: No. Long answer: Maybe (very likely not yet, but hopefully soon). Coincidentally it was recently posted on reboot.pro about a newish boot manager/Windows OS loader that may (or may not) include a layer of BIOS compatibility mode via the SeaBIOS, JFYI, Quibble: http://reboot.pro/index.php?showtopic=22748 As said there, it seems like being yet very experimental and its main scope is different (booting current Windows on EFI with OS residing on a "foreign" filesystem - BTRFS) but from the very scarce and confusing description it sounds like it could work. Still it is the usual "compile as you please" nonsense of many open source projects [1] which limits the possibility to test to a limited number of people with the capabilities to setup a correct build environment and smooth out the (inevitable) quirks preventing a successful compiling[2]. jaclaz [1] the usual Rule being that if you need to compile it, it won't [2] maybe I am too much a pessimist on these, but failure to compile has been the usual outcome of *any* project I ever tried to compile in the last 20 years or so Link to comment Share on other sites More sharing options...
