I'd have to google what the acronym stands for but it's a utility in UEFI which allows 'legacy' booting, that is, booting via the MBR. > So am I as I've not bought a board with a UEFI bios on it yet. However, > there is not a single reason trinity, to my knowledge, writes anything > to the MBR. not sure what you mean: that's where some of the partitioning code used to lodge. I forget the details but something like BIOS jumps to code in the MBR which knows the partitioning scheme. UEFI, replacing BIOS, uses a different process. details cloudy. the crucial code is in a uefi-boot partition. I don't like it defaulting to NetRunner since I wanted it to default to grub and then I could manage everything there. I'd like Windows, NetRunner (soon Maui?) and Trinity. I may remove NetRunner in the longer run but it's been fun and useful. f. -- Felmon Davis Getting into trouble is easy. -- D. Winkel and F. Prosser
