Description:
Legacy BIOS implementation
SeaBIOS is a legacy BIOS implementation, aimed at supporting not only emulated hosts such as QEMU, but also real hardware. . Note, however, that SeaBIOS does not handle early initialization of core chipsets, so don't even think of flashing it to your board (look at Coreboot for that).
