    Hello, I am using LG T1-5316A9.
    When I checked SLIC for this laptop, it did not had any of SLIC.

    So, I requested to LG for new BIOS and after I install the new bios, I saw SLIC table from Everest.

    However, I was unable to activate my laptop, so I checked SLIC table from the firmware.

    After I check real SLIC, I realized that the bios is missing 3/4 of SLIC.
    There are only names but no data.(as you can see from the picture)
    Also, I checked SLIC through acpiscope and the dump from the bios file.
    So I guess this is correct result of my SLIC.

    I was searching the web for long time, but could not find SLIC for LG.


    So, does anybody can post SLIC for LG so I can use it for my laptop??



    Best regards.

    Here is the LG slic and the matching certificate.

    Code:
    LG = "LGE   LGPC    "
    HEX = 4C 47 45 20 20 20 4C 47 50 43 20 20 20 20
    OEMCERT CRC = 69A660CA

    Thank you very for sharing the file.
    However, it still remains me some question.

    Ori SLIC

    Your SLIC

    As you see at the end, there are some difference of SLIC.
    Do I have to replace whole SLIC (374bytes) for the laptop?
    or should I have to replace the part where the my original SLIC showing FFFFFF....


    I just concern about it might break my laptop :p

    If it was desktop mobo, I would not be so scared lol.


    Best regards

    You have to replace the entire SLIC table (all 374 bytes). If you are interested in the technical aspect of the differences, read on.

    I have highlighted the two differences. The single byte colored in red is the SLIC checksum byte. The entire SLIC table must have a checksum of 00h(CRC8) in order to be considered valid. If is not, you would manipulate this byte so that the checksum is equal to 00h. The SLIC table I posted already has the correct checksum byte so don't mess with it. Just use it as is.The 4 bytes colored in blue is the OEM revision number. This number is in endian format (read backwards by the computer). So, if you use Acpiscope, your OEM revision number would be "1h". After you successfully mod your BIOS with the SLIC I posted, then your OEM revision number would be "6040000h"

    Post your results.
