SeaBIOS implements a whole bunch of legacy BIOS services, including option ROM processing and the BBS. > Where I see e820 table which is to be passed to OS, in order OS to > understand what memory it can use.

How GRUB2 replaces all of these functionalities? It doesn't and is not supposed to. It is only used to load the operating system, not to create a BIOS environment. If you need a legacy BIOS or UEFI then you do not use GRUB2 as (only) payload. > who/what entity is replacing missing SeaBIOS functionalities? None. With GRUB2 as payload, no legacy BIOS environment is present, and that's a good thing. //Peter -- coreboot mailing list: [email protected] https://www.coreboot.org/mailman/listinfo/coreboot
