Surely it isn't the chipset which determines what disk format you can boot from, it's the firmware. I know the BIOS on my new intel PC boots my new Bullseye install which I did with MBR boot partition and no ESP. (Not having setup EFI booting before I stuck with what I knew). The boot selection menu on my motherboard also lets me select between the MBR and EFI boot on my Debian installer USB stick, so seems happy to do both. I've read many places that this experience of legacy boot support isn't universal though, but I'm pretty sure it's a firmware not chipset issue. -- Tixy
