Starting up with coreboot and SeaBIOS, the screen is completely black for around 30 seconds before my on-disc bootloader (grub2) is loaded and displayed.
I'm assuming SeaBIOS counts down with some timer before launching the on-disc bootloader but I don't see anything.
I want to use coreboot in text-mode so I'm not including a VGA rom.
That might be why you are getting the delay. Try adding it and see. I ran into the delay too and think that's what fixed it.
According to lspci (attached), I have two VGA devices:
You might need to edit src/device/Kconfig with:
config MULTIPLE_VGA_ADAPTERS bool default y
Try a 'cbmem -t' to see how long coreboot itself took to boot. There might be some delay somewhere causing it to take longer to boot (current system I'm on, it takes 8 seconds, and on other systems I saw it take 15 seconds, because it waits for the ME to respond until it times out) so it might not all be seabios' fault. Also I just tried removing the VGABIOS and setting Coreboot to run the GOP driver, and I got a black screen in seabios (even in grub, screen shows text only after linux boots and inits the driver I think). I'd suggest you try the proper vgabios and no GOP driver, just to see if it helps, then see what happens without the vgabios. Note: i only have one VGA device here.
