    I spent days looking for the answer and had a hard time so posting this as a new thread to help anyone trying to unhide the full SLIC table on DELL 13th Generation PowerEdge servers (R730, R930, etc.).

    On older PowerEdge servers, the SLIC table was built into the BIOS but "hidden" and needed certain Dell tools like ASSET.COM ran on a DOS boot to enter BIOS MANUFACTURING MODE which unhides the full table. Setting the asset to "ASSET PASS:12/31" or "ASSET PASS:12/34" enabled this mode. But on newer UEFI/GUI based PowerEdge servers with Lifecycle, these tools no longer work.

    So the key question is how to enter BIOS MANUFACTURING MODE on these new servers? Surprisingly, it's even easier now. There's a field in the BIOS for the Asset Tag. Just set this field to "PASS:12/34", reboot and the system will be in BIOS MANUFACTURING MODE. Reboot the machine again to exit the mode, but the SLIC will be fully unhidden! This was tested on a PowerEdge R930. With the newest BIOS, SLIC Toolkit reports SLIC 2.4.

    1. F2 (enter BIOS) -> System BIOS-> Miscellaneous Settings
    2. Enter "PASS:12/34" in the Asset Tag field, then exit and save settings
    3. System will reboot into BIOS MANUFACTURING MODE. Let it go through POST completely, then reboot again to exit BIOS MANUFACTURING MODE. *NOTE*: You may have to go back into the BIOS to reconfigure some settings, such as the boot order, etc.

    EDIT: This trick also works with 12th Generation Servers too (R620, R720, etc.)

    I had successed open slic from this method.Thanks.

    But When I entered the bios,I must typed "/s servertag" first,and secondly typed "PASS:12/34".
    Only done 2 steps all by sequence the machine will entered factory mode,or else not enter if I only typed "PASS:12/34" only.

    Holpfuyly it can help someone.I'm R730.

    Thanks again.

    It didn't work on power edge T20. I can't find a way to unlock Slic 2.3 or 2.4 on it. It's frustrated.

    Does this work on a Poweredge T130? Also if I change the asset tag name can I easily change it back to something else or blank it out later if I want? I'm wondering if I mistype the asset tag that this might be a one-shot kind of deal. Also, I'm just trying to learn and if I sell this later I might want to revert it back to factory specs.

    It's been a few years since I posted this, but this method still works on servers released today. Just tested this on an R940 and T340.

    For those that don't seem to have success: are you checking the SLIC table using SLIC Toolkit? If so, make sure the server is booted in BIOS mode and not UEFI mode. I've noticed that in UEFI mode, SLIC Toolkit reports errors -- but if you run RW Everything in UEFI mode, you'll notice the SLIC table is there.
