Building coreboot

Currently there is no special target for the ASUS A8V-E Deluxe in coreboot. Instead, we use the ASUS A8V-E SE target.

First, place your payload (usually FILO) into /tmp/filo.elf and build coreboot as usual:

$ cd target
$ ./buildtarget asus/a8v-e_se
$ cd asus/a8v-e_se/asus_a8v-e_se
$ make

The resulting coreboot.rom (512 KB) can now be flashed on a ROM chip.

It's possible to use a 1 MB ROM chip on this board. You'll have to change ROM_SIZE in targets/asus/a8v-e_se/ to make coreboot.rom bigger for that.

Booting coreboot

  • Booting from SATA port 1 works using FILO and this config (I have my root filesystem on /dev/sda2 as viewed from Linux):
 kernel=hda2:/vmlinuz initrd=/initrd.img root=/dev/sda2 console=tty0 console=ttyS0,115200
  • Booting from SATA port 2 doesn't yet work, I'll investigate.
  • Booting from IDE doesn't yet work, I'll investigate.

Comparing boot time

This is an ad-hoc test with pretty much no attempts at optimizing boot-times.

  • BIOS: I disabled the boot logo, SATA RAID blob execution (i.e. I set "IDE mode" in the BIOS menu), floppy detection/usage in order to kill the most obvious delays.
  • coreboot: Stock svn as of r3198, but with console logging level increased to 9 (i.e. slower bootup is to be expected).

Both the proprietary BIOS and coreboot do execute the VGA BIOS ROM from the PCI-E x16 graphics card. I'm booting from a SATA drive, using FILO in coreboot and pointing it at the menu.lst on the SATA drive, and GRUB when booting with the proprietary BIOS. The OS is a standard Debian unstable installation with 2.6.24 Linux kernel.
