    Hi AndyP

    I have modded several different variety and makes of bios and have not encounter so far with any issue with any one of them However today while modding D630_A19.exe to insert SLIC2.1 using phoenix tool 2.59, an error message was reported as follows “Error 6 - Arithmetic operation resulted in an overflow.” and failed to generate a new SLIC2.1 inserted exe file. No such error message was encountered when I modded D630_A17.exe

    Started phoenix tool.
    selected bios executable
    Supplied RW File
    Verified Dell cert (to be sure)
    clicked "Go"
    and no D630_A19_SLIC.EXE was created

    Any Idea, grateful for your thoughts.

    Thank you very much in advance!

    Thanks apologized for providing me the links to the mode BIOS for Dell D360

    From the links provided I down loaded the file wich contained the original and modded bios

    At first glance I noted that the file size of the original D630_A19.exe ((1,241,473 bytes) was different to that of the modded D630_A19_SLIC.exe (3,682,304 bytes)

    Furthermore on line virus check indicated Trojan's in the D630_A19_SLIC.exe

    SHA256: c61caf3c420e3bdbd64cf87443fc418ea3fcc84e8c9fde94114cec859dfd5f72
    File name: D630_A19.exe
    Detection ratio: 0 / 57

    SHA256: 9081237a770b9064d9f155ae060dc21321d7a25fcf5872ed193144dabd233ba6
    File name: D630_A19_SLIC.exe
    Detection ratio: 9 / 57

    Thus my request on the cause of the error message so that I can modd my own BIOS

    Thanks for you help and Kind Regards

    The size difference is caused by the packing by Dell Client Configuration Utility. The packed file isn't a virus but its nature (auto-extract & reboot Windows) confuses some AVs.

    You can use Phoenix Tool v2.14 to mod the bios but still you need to pack the modded bios with DCCU (and again you get those false-positives).
