From 7d1fd1cc6a176d15d8a938cd0df9868cbbb86d8f Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Thu, 21 Nov 2024 12:29:05 +0000 Subject: rom.sh: Support SeaUBoot for 64-bit x86 U-Boot Same concept as SeaGRUB, but for U-Boot. SeaBIOS starts, but has a bootorder file loading U-Boot first, from flash. You can interrupt it with the ESC menu, to boot something else in SeaBIOS, including GRUB. With this, we can effectively provide extremely user-friendly UEFI-first setups in Libreboot. Take that, edk2!
