Unless I'm missing something, the linux boot sequence uses IBM-PC BIOS functions. I found a number of int 0x13 (diskette services) and int 0x10 (video services) calls in arch/i386/boot/setup.S. Even Grub makes heavy use of BIOS services- a quick grep revealed 23 different BIOS calls,
using
services 0x13 (disk), 0x10 (video), 0x1a (RTC), and 0x16 (keyboard).
That's not a problem -- these are not mandatory and even now there are some people that run Linux on ia32-based embedded systems. They have no BIOS and the kernel is started from flash memory.
Hi, Brian,
that is exactly what I was looking for all the time --- just booting Linux on a bare machine whithout any BIOS. Could you give me some pointers on that?
