I disagree, you can use Linux or Windows to create GPT FAT partitions for DOS. So you would want to start by DOS being able to use them ;-) Jeremy is looking into the topic and as you know, Bret has recently donated code from his DOS USB drivers for interpreting GPT to the public domain. His drivers already support GPT FAT partitions on USB media. Once our kernel also supports GPT, you can wonder about booting it from there, too. However, you would still not boot in UEFI mode anyway, because without legacy support, you also lack BIOS int services. For those, you need an UEFI CSM, which is how legacy support would give you a "BIOS" otherwise. The kernel and many apps require BIOS services. > Then find/make an MBR able to boot the active GPT partition. Only later. But it is great to be able to access GPT partitions as DOS drive letters even when you still have to boot from something else :-) Eric _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
