    How to insert SLIC 2.1 into a Fujitsu Siemens Scaleo Li 2642.


    The motherboard of this computer comes from ECS and has the model
    designation G31T-M2. However, do not assume that a standard ECS BIOS from a similar model will work. In fact, wise from other such arrangements between producer firm and marketing label, we can assume it probably won't.

    Fujitsu Siemens is nowadays two divorced companies, PC support for F-S computer products is handled by Fujitsu (without the Siemens).

    The BIOS of this motherboard comes from AMI and sports a fancy Fujitsu Siemens logo at post. The shipped BIOS is already at SLIC 2.0 level, meaning it will OEM activate Vista, if a suitable version of Vista is used as operating system.

    The mystery of this BIOS is in the seemingly odd way it is updated. Fujitsu will offer you a Linux CD ISO file which needs to be burned to a physical CD. Then you can boot up the system with that CD and the rest will all go automagically. If you examine the ISO file (or the burned CD) you will not see anything resembling a 512KB ROM file.

    OK, so what to do?

    To begin with, download that ISO file from Fujitsu's support pages. You will need to provide the support form on the page with the motherboard's serial number. If you have a working system you can get that serial number with a program like Belarq Advisor or similar. You can also search for this file:

    FTS_BiosupdateECSG31TM2V304ISOImage_304_1020647.iso

    Burn that image to a CD and test the CD on another computer than your Scaleo Li 2642. Why so, you ask? On the Scaleo the BIOS will be flashed without questions. On another system there will be an error and you will be thrown to DOS. This CD is your fallback in case anything goes wrong. If your current BIOS is lesser than v.3.04 you should flash it with this original BIOS.

    Next step is to transfer this ISO image to a bootable USB flash stick. Not all are bootable, btw. Run UltraISO as Administrator, load the above ISO, choose Bootable, choose Write Disk Image and choose your USB stick. If the menus in your UltraISO seem different it may be because you have a different version or a different language (mine is Swedish).

    Everything on the USB will be erased.

    If you've done everything right, your USB stick will now behave like that CD mentioned above. Test it on another system than your Scaleo. On that system you will get an error and be thrown into DOS command line.

    Now things get interesting! Your DOS system will recognize three

    drives; A:, C: and Z:.

    Drive A: will be the root of the ISO CD. Nothing much to see there.
    Drive C: will be what the system has booted from, which is a DOS system.
    Drive Z: will be a RAM disc similar to C:.

    To save the BIOS for further editing, copy the *.ROM file from C: to A:. The command for that is:

    copy 080130.ROM A:\

    While you're at it, also copy the START.BAT and AFU408.EXE files. These are the batch file and the flasher program needed for correct flashing of the BIOS. The DOS commands are:

    copy START.BAT A:\
    copy AFU408.EXE A:\

    Now you will have three additional files in the root of your USB stick, these are DOS files and will be accessible to you in Windows or any other system.

    Turn off your system and remove the USB stick. Boot up Windows and put the stick back. The BIOS file, 080130.ROM, can now be copied to the HDD and injected with a SLIC 2.1 signature with the aid of Amitool162. Just accept all default settings that Amitool proposes. You should make sure to have a Fujitsu Siemens digital signature file (SLIC 2.1) ready and point to it in the program. Google for SLIC 2.1 BINS if you don't have it already.

    The Amitool program will create the file 080130_SLIC.ROM and leave the original 080130.ROM file intact.

    The final step is to prepare a DOS boot media and copy the files we need to it. Easiest is probably to prepare a bootable USB stick. Mind you, the stick you prepared before can't be used for this. Well, the stick can, but not the content.

    After you've made a barebones DOS boot disk, copy the necessary files to it. Repace X with the letter of your bootable DOS USB disc:

    copy START.BAT X:\
    copy AFU408.EXE X:\
    copy 080130_SLIC.ROM X:\

    You must also change back the name of the 080130_SLIC.ROM file to the original file name 080130.ROM. The DOS command is:

    ren 080130_SLIC.ROM 080130.ROM

    (That's ren, not rem!)

    Do this in Windows, since real DOS will have trouble displaying file names that exceed 8+3 characters. Boot with the DOS USB stick and just type START and hit Enter.

    Hopefully, everything went well and the BIOS of your Scaleo Li 2642 will now feature the SLIC 2.1 signature.

    If not, use the previously made fallback CD to set things right and start over.



    Pitfalls in BIOS flashing:

    Use only the BIOS intended for your motherboard. Not some close enough file or something that is really from the original manufacturer but you will use it for brand X. In this case ECS to Fujitsu Siemens. Generally this will not go well.

    BIOS mismatch is a much more serious issue than driver mismatch. Do not play Russian Roulette with your system. Have a clear understanding of what you are doing. Don't chance it and hope for the best. The best may happen, but the worst may happen as well. How unnecessary is that?

    If you plan on doing several different modifications to your BIOS, don't do them all at once. For instance, the SLIC modification should be done after you have successfully modified the BIOS boot logo, not before.

    In fact, make as few BIOS mods as possible to one single BIOS. You will normally not interact with the BIOS as much as with the OS you're running. If the BIOS modding thing really is your cup of tea, maybe you should look at the Coreboot project instead. Coreboot allows for SLIC 2.1 injection and any other modification you can imagine.

    Good luck!
