This page describes how to use LinuxBIOS on the AZZA PT-6IBD.

After noticing that my motherboard is not fully supported I found much appreciated help on IRC. I submited some of my data to the guys there and with some patching things finally booted. ;)

Hardware

• Northbridge: Intel 440BX
• Southbridge: Intel 82371EB
• Super I/O: Winbond W83977EF

To check the hardware the way LinuxBIOS sees it, I used already made programs that LinuxBIOS offers. As I use Gentoo, I hacked up a few ebuilds that install the latest svn versions of these programs. You can find them on this Gentoo Forums thread.

# superiotool -dV

Superiotool showed me which (if any) Super I/O chip is on the motherboard.

# flashrom -V

This tool showed me which ROM chip is used in the mainboard, and whether Flashrom supports it.

Build process

Checkout and Patching

After you get all the data from your computer by looking with eyes on the motherboard and checking the same things with the above programs, you need to do the following.

Make yourself a directory and checkout the svn repository for LinuxBIOSv2:

# svn co svn://linuxbios.org/repos/trunk/LinuxBIOSv2

If you want to use the patch with Gentoo ebuilds, add it as specified here.

FILO

Then get FILO from svn:

# cd ..
# svn co svn://openbios.org/filo/trunk/filo-0.5

First:

# cd filo-0.5
# make

Now edit the Config file with your favorite editor as you wish.

# nano Config

Here is what I ended up with:

USE_GRUB = 1
MENULST_FILE = "hda1:/boot/grub/menu.lst"
MENULST_TIMEOUT = 6
IDE_DISK = 1
VGA_CONSOLE = 1
PC_KEYBOARD = 1
SERIAL_CONSOLE = 1
SERIAL_IOBASE = 0x3f8
FSYS_EXT2FS = 1
SUPPORT_PCI = 1
PCI_BRUTE_SCAN = 1
LINUX_LOADER = 1

After you're satisfied do make again and copy filo.elf to /tmp:

# make
# cp filo.elf /tmp

Building LinuxBIOS

Lets create the linuxbios.rom file for the motherboard:

# cd ../LinuxBIOSv2/targets
# ./buildtarget azza/pt-6ibd && cd azza/pt-6ibd/pt-6ibd && make

We ended in the motherboard's directory, where the linuxbios.rom file resides now.

Flashing LinuxBIOS

Let's put the newly made linuxbios.rom file on the ROM chip. Be sure you have the right ROM chip in the board, so you don't accidentaly ruin your original chip.

Then do

# flashrom -wv linuxbios.rom

Reboot

Now reboot the machine and see if it boots ok.

When I did the above procedure my LinuxBIOS made use of only 64 MB of RAM. Some additional patches are still needed (this is being worked on).

But the result is fantastic anyway. Usual time for boot was long, 10-15s at least, now its close to 0s.
