Revision as of 19:34, 15 January 2015

Which board do you have?

The GIGABYTE GA-M57SLI-S4 seems to exist in 4 versions as of 2007/05.

There is a version with a PLCC socket for the BIOS chip (socketed BIOS), but this might be a pre-production board since nobody has so far (2007/03) confirmed the purchase of a GA-M57SLI-S4 board with socketed BIOS. The mainboard photo on the backside of the GA-M57SLI-S4 box shows a ROM socket too.

There are 4 volume revisions, 2 with PLCC32 (v1.0, v1.1) (soldered BIOS) and another 2 with single 8 pin SOIC (SPI). All 4 have unpopulated secondary pads. For the PLCC32 versions, the procedure outlined below can be used to add a ROM socket.

A PLCC32 revision of the GA-M57SLI-S4
An SPI revision of the GA-M57SLI-S4

recent legacy BIOS variants are (for fallback purposes):

  • F15E for GA-M57SLI- S4 (rev. 1.0) non AM3, plcc (fifth variant: socketed plcc, maybe on early sample board only)
  • F15E for GA-M57SLI- S4 (rev. 1.1) non AM3, plcc (not flashable with legacy tool here (no 'chipset support')
  • FHL for GA-M57SLI- S4 (rev. 2.0) AM3 ready, soic
  • FJD for GA-M57SLI-DS4 (rev. 2.0) AM3 ready, soic

F15E is binary identical for hw rev. 1.0 and 1.1. So there are 3 variants of legacy BIOSes, if you count -DS4 as the "fourth" M57 board and not as a separate board form the -S4.

Before you begin

The fact that the BIOS is soldered onto the board complicates matters considerably, because it means that one flash of a faulty image will render your board unusable (it will be 'bricked'). Top Hat Flash does not work with the SST 49LF040B 33-4C-NHE soldered onto the GA-M57SLI-S4, but might work with other chips (FWH). This means a hardware hack is necessary to prevent accidental bricking of the board.


This wiki page is maintained by Ward Vandewege (ward at gnu dot org).

If you're going to work on this board, you need a backup plan in the event you flash a faulty BIOS image. You have been warned!

PLCC32 hardware hack

If you have a PLCC32 revision, it is possible to desolder the BIOS chip, and replace it with a PLCC socket. You will need some tools (heat gun/pencil, good soldering iron, etc) and soldering experience to do that. The other option is to add a PLCC socket to the empty position next to the soldered-on BIOS chip. With an extra resistor and a switch, this allows switching between 2 BIOS chips. This has been documented carefully by ST; see his instructions.

If you don't feel like doing this yourself, you could try to find a commercial service to do it for you. One way to find a shop is to look for game console modification shops, they do this sort of thing (and more advanced things) all day and should be able to help you for around $50 if you bring the needed components (PLCC socket, resistor, wire and switch). Possibly a friendly TV or radio repair shop could help too, but they may not have suitable soldering equipment for the surface mount parts.

Once you put a socket on the board, you will also discover that the RD1-PMC4 BiosSavior does not work with this motherboard: the RD1's built-in chip seems to be incompatible with the mainboard. This means you will need to hot-swap BIOS chips until you have a working coreboot chip. Plugging your BIOS chip into the RD1 and switching it to 'ORG' does work though. I have used the BiosSavior to ease hot swapping; it's a lot easier to pull out the BiosSavior and replace the chip plugged into it than to replace the ROM chip on the board.

This is the list of BiosSavior resellers: IOSS. In the US, FrozenCPU seems to have stock (verified 2007/04). Eksitdata in Sweden also seems to have stock (verified 2007/03).

SOIC hardware hack

If you have an SOIC revision, you can add a second SOIC chip in the unpopulated position, and use a switch to toggle between both chips.

The most recent instructions by Peter Stuge can be found here [1]. This is the recommended modification. Peter's company also sells pre-modified boards if you don't want to do the soldering, contact peter at stuge dot se for more information. Also, you may watch Peter's video lecture on coreboot available at youtube asf. for recent info.

Older instructions can be found here here, and here are some photos. These instructions have been confirmed to work.

It's also possible to put a SOIC socket on the second pad, as documented by Harald Gutmann, with pictures here and here.

Here's are a few pictures of a completed modification using the older instructions:

Flashrom

PLCC32 chips

Flashrom works fine both under the proprietary BIOS and coreboot. Use revision 3088 or higher.

SPI chips

Flashrom works well on the SOIC version of the board and can detect various SPI chips, including the factory soldered MX25L4005.

Payload

Coreboot requires a payload to boot an operating system.

If you want to boot from the network, you will need to use Etherboot.

If you want to boot from an IDE drive, SATA drive, USB stick or CDROM, you can use FILO.

Another possible payload is 'linux-as-a-bootloader' (LAB). You will need a 1MB ROM chip (the GA-M57SLI-S4 comes with a 512KB ROM chip) for this payload. It consists of a (stripped down) kernel + busybox, which can then be used to kexec a kernel from disk. If your disks are playing up, you will still have a busybox environment on boot, which could be useful for debugging.

Buildrom vs. manual build

You can build a coreboot image with a kconfig-style configuration tool (buildrom) if you want to use FILO or LAB. This is by far the easiest way to build a ROM image. Continue to the Buildrom section.

If you want another payload or would like to get closer to the metal, you can use the manual build method outlined below under Manual build.

Buildrom

Skip this section if you want to do a manual build; in that case jump to Manual build below.

Check out buildrom: 

 svn co svn://coreboot.org/buildrom

Now configure buildrom: 

 cd buildrom/buildrom-devel
 make menuconfig

Configure to your liking. If you use the LAB payload, make sure to exclude the kexec binary and boot menu from the initramfs, otherwise your image will be too big. Please note that currently only the FILO and LAB payloads have been tested. The other payloads likely require some more work before they will be useable. Patches are welcome, of course. 

 make

If all goes well, you should now have a ROM image file 

 deploy/gigabyte-m57sli.rom

If you are building a FILO payload, it will be exactly 512KB in size. If you are building an LAB payload, the image will be 1MB.

FILO payload

Skip this section if you use the LAB payload.

When using FILO in GRUB emulation mode, it's important to get a few details right in your GRUB boot stanza. This is what mine looks like: 

title   Ubuntu LB, kernel 2.6.21-rc3
root    (hd4,0)
kernel    /boot/vmlinuz-2.6.21-rc3 root=/dev/sda1 ro acpi_use_timer_override console=tty0 console=ttyS0,115200
savedefault
boot

Note the root device - FILO sees the first SATA device as hd4.

In order to get serial output from GRUB, you will also need to add something like this to your menu.lst: 

 # serial port 0
 serial --unit=0 --speed=115200
 terminal --timeout=15 serial console

LAB payload

Skip this section if you use the FILO payload.

The LAB payload expects a file /lab.conf on /dev/sda1 with contents like this: 

 CMDLINE="root=/dev/sda1 ro console=tty0 console=ttyS0,115200"
 KERNEL="/vmlinuz-2.6.22.1"
 INITRD=""
 VT="1"

This is the kernel that you will be running after boot. It will be kexec'ed by the kernel that is burned into your ROM chip.

You will also need a statically linked copy of kexec, which the LAB payload expects to reside at 

 /kexec on /dev/sda1

If you are on Ubuntu, you can easily recompile your kexec package to be statically linked by following these instructions: 

 cd /usr/src
 apt-get source kexec-tools
 export LDFLAGS="-static"

Now edit kexec-tools-1.101-kdump10/kexec-tools-1.101/kexec/Makefile, change line 53 to 

 $(CC) $(LDFLAGS) $(KCFLAGS) -o $@ $(KEXEC_OBJS) $(UTIL_LIB) $(LIBS)

(you're adding the LDFLAGS variable) 

 cd kexec-tools-1.101-kdump10 
 dpkg-buildpackage -rfakeroot -b
 cd ..
 dpkg -i kexec-tools_1.101-kdump10-2ubuntu2_i386.deb

Adjust the package name as necessary for your distribution.

If you want to build the latest kexec from Debian Sid, you're going to need to be a little more careful. Set -static: 

 export LDFLAGS="-static"

Then build the package 

 apt-get source kexec-tools -b

This will fail more or less like this 

  $ gcc -static -lz   -o build/sbin/kexec kexec/kexec.o kexec/ifdown.o kexec/kexec-elf.o kexec/kexec-elf-exec.o kexec/kexec-elf-core.o kexec/kexec-elf-rel.o kexec/kexec- elf-boot.o kexec/kexec-iomem.o kexec/crashdump.o kexec/crashdump-xen.o kexec/arch/i386/kexec-x86.o kexec/arch/i386/kexec-elf-x86.o kexec/arch/i386/kexec-elf-rel-x86.o kexec/arch/i386/kexec-bzImage.o kexec/arch/i386/kexec-multiboot-x86.o kexec/arch/i386/kexec-beoboot-x86.o kexec/arch/i386/kexec-nbi.o kexec/arch/i386/x86-linux-setup.o kexec/arch/i386/crashdump-x86.o kexec/purgatory.o libutil.a

/usr/src/kexec-tools-20080324/kexec/kexec.c:505: undefined reference to `gzerror'
collect2: ld returned 1 exit status

The problem is that the -lz really needs to go at the end of the gcc command line - otherwise it gets filtered out by gcc. When it encounters -lz, it has not yet seen any need for the libz library so it automatically removes it. Manually running 

gcc -static -o build/sbin/kexec kexec/kexec.o kexec/ifdown.o kexec/kexec-elf.o 
  kexec/kexec-elf-exec.o kexec/kexec-elf-core.o kexec/kexec-elf-rel.o kexec/kexec-elf-boot.o 
  kexec/kexec-iomem.o kexec/crashdump.o kexec/crashdump-xen.o kexec/arch/i386/kexec-x86.o

  kexec/arch/i386/kexec-multiboot-x86.o kexec/arch/i386/kexec-beoboot-x86.o kexec/arch/i386/kexec-nbi.o 
  kexec/arch/i386/x86-linux-setup.o kexec/arch/i386/crashdump-x86.o kexec/purgatory.o libutil.a -lz

fixes the problem and gives you a static copy of kexec in build/sbin/kexec.

You can tell if your copy of kexec is statically linked by running 'file' on it: 

 file /sbin/kexec

If all is well, you will see something like this: 

 /sbin/kexec: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.0, statically linked, for GNU/Linux 2.2.0, stripped

The binary will also be considerably larger than its dynamically linked cousin.

Note that you must build a 32-bit version of kexec, because buildrom puts a 32 bit kernel into the ROM image. A 32-bit kexec can kexec into a 64 bit kernel, so if your system is 64 bit this will work just fine.

The LAB code currently expects lab.conf and kexec to live in / on /dev/sda1.

Manual build

Skip this section if you used buildrom; in that case jump to Burning coreboot below.

Building the payload

In order to boot from a SATA disk, we use FILO.

Once you've downloaded FILO, you will need to put a file 'Config' in its root tree. An example can be found in the distribution, called 'defconfig'.

You can configure FILO to load GRUB. Here's my Config, which does that: 

 # Use grub instead of autoboot?
 USE_GRUB = 1
 # Grub menu.lst path
 MENULST_FILE = "hde1:/grub/menu.lst"
 # Driver for hard disk, CompactFlash, and CD-ROM on IDE bus
 IDE_DISK = 1
 # Add a short delay when polling status registers
 # (required on some broken SATA controllers)
 IDE_DISK_POLL_DELAY = 1
 # Driver for USB Storage
 USB_DISK = 1
 # VGA text console
 VGA_CONSOLE = 1
 PC_KEYBOARD = 1
 # Enable the serial console
 SERIAL_CONSOLE = 1
 # Serial console; real external serial port
 SERIAL_IOBASE = 0x3f8
 SERIAL_SPEED = 115200
 # Filesystems
 FSYS_EXT2FS = 1
 FSYS_ISO9660 = 1
 # Support for boot disk image in bootable CD-ROM (El Torito)
 ELTORITO = 1
 # PCI support
 SUPPORT_PCI = 1
 # Enable this to scan PCI busses above bus 0
 # AMD64 based boards do need this.
 PCI_BRUTE_SCAN = 1
 # Loader for standard Linux kernel image, a.k.a. /vmlinuz
 LINUX_LOADER = 1

Because physical disks take a while to spin up, I've had to add an extra delay to FILO: 

Index: main/filo.c
===================================================================
--- main/filo.c (revision 34)
+++ main/filo.c (working copy)
@@ -60,6 +60,7 @@
     
     /* Initialize */
     init();
+    delay(5);
     grub_main();
     return 0;
 }

This will make FILO wait 5 seconds before probing the disks, making sure that the SATA disk is ready.

In order to get serial output from GRUB, you will also need to add something like this to your menu.lst: 

 # serial port 0
 serial --unit=0 --speed=115200
 terminal --timeout=15 serial console

Now execute 'make', which will generate a filo.elf file that will be your payload. You will need to refer to this file to build coreboot as explained below, because it gets included in the coreboot ROM image.

Your menu.lst entry

When using FILO in GRUB emulation mode, it's important to get a few details right in your GRUB boot stanza. This is what mine looks like: 

title   Ubuntu LB, kernel 2.6.21-rc3
root    (hd4,0)
kernel    /boot/vmlinuz-2.6.21-rc3 root=/dev/sda1 ro acpi_use_timer_override console=tty0 console=ttyS0,115200
savedefault
boot

Note the root device - FILO sees the first SATA device as hd4.

Also, the GA-M57SLI-S4 will not boot unless you add acpi_use_timer_override as a kernel option - and use a modern kernel (tested on 2.6.20.1 and up). Hopefully this will be fixed in newer kernels. If you have a somewhat older kernel (tested with 2.6.16 and up), add these options: apic=debug acpi_dbg_level=0xffffffff pci=noacpi,routeirq snd-hda-intel.enable_msi=1.

Current status of the coreboot v2 tree

Use revision 3088 or higher.

Building coreboot

See the Build HOWTO for information on how to build coreboot for this board.

Burning coreboot

Make SURE that you have a fallback position: a ROM chip with backup copy of your factory ROM image (you can make one with flashrom), and either a socket on the board to plug the backup chip into, or the tools and skills to remove a 'bricked' BIOS chip from the board and replace it with a socket for the backup chip.

If you do not prepare properly, you are likely to brick your motherboard. You have been warned!

You can use flashrom to write the image: 

 flashrom -p internal -w coreboot.rom

(that's assuming the image is called coreboot.rom).

TODO

  • As of >=r4362 all PCI and PCI-E slots should be initialized correct and work fine. For hardware rev.1 it would be nice to get further test results.
  • There is also still an issue with I2C, which causes X startup to be very slow. You can bypass this problem by adding 
 Option   "NoDDC2"
to your "Device" section. Update (14.9.2009): Is this a v1 specific problem? Is this problem maybe fixed with the IRQ-Fix patch?

If you can help out with these issues, please join the mailing list and let us know!
