SeaBIOS doesn't boot from secondary hard drive with OS if primary hard drive is empty
When I have 2 SATA disks attached to my board, and only second priority device is with OS, SeaBIOS doesn't boot. The "empty" disk doesn't have MBR, so SeaBIOS doesn't stuck on it, it goes to the end message "No bootable device. Retrying in 60 seconds." But if I manually press "ESC" and choose correct disk in interactive promt, system boots successfully. Two logs attached to the message (with and without "ESC" interaction). I use SeaBIOS (d7adf6044a4c772b497e97272adf97426b34a249) as a payload to coreboot.

That's a limitation of the BIOS design - only one drive can be designated as "C:" and only that hard drive is bootable (without a full reboot). So, there's no good way to attempt to boot from a different hard drive should booting from the first hard drive fail. You can change the default order of drives and thus change which drive gets designated as "C:". See the bootorder file: https://www.coreboot.org/SeaBIOS#Configuring_boot_order -Kevin
