Hi all,
I'd like to learn more about SeaBIOS boot order, but unfortunately I wasn't able to find the answer to my question on the wiki page: https://www.coreboot.org/SeaBIOS#Configuring_boot_order
I would like to add a bootscript for SeaBIOS to search for USB boot devices before falling back to the hdd or PXE.
If I have USB bootable media plugged in, SeaBIOS seems to immediately boot from the hdd. I'm not able to boot from USB unless I physically unplug the SATA connection.
When I look at the console log in cbmem, I don't see SeaBIOS searching the USB controller at all.
It's an Ivy Bridge platform.
SeaBIOS log from cbmem: Searching bootorder for: /pci@i0cf8/*@1f,2/drive@0/disk@0 Searching bootorder for: /pci@i0cf8/pci-bridge@1c,3/*@0 Press ESC for boot menu.
