    Hi there, just tried the modded bios for a Compaq nx6310 earlier in this thread. All went well, it rebooted ok, but didn't seem to mod for slic 2.1. Slic toolkit says Pubkey is ok but Marker is not. If I manually load the certificate and Slic.bin file for hp compaq it seems happy. so i'm guessing the cert I'm using is ok. Any help would be great.

    Hi, I'm a complete noob when it comes to bios modding, I have a Compaq cq60-415so I should have opened the SATA settings. Here's my bios: h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-76825-1&lc=en&dlc=en&cc=us&os=4062&product=3984781&sw_lang

    Are there hotkeys to open the advanced settings?

    Hi there i found something curious, i did a backup of my 6710b bios with BIOS_Backup_TooKitV2.0, i check the file with HXD and see that the backup has my serial number model etc, later y add the HP slic 2.1 mark to the backup on the 2 marker & create de ROM.cab, i flashed with HPQFlash4253_patched, i know everyone will say, that was done with no effect on any of the two slic marks, but when i create a new backup with BIOS_Backup_TooKitV2.0 my new backup has the slic 2.1 table on the first mark but the second one doesn't change, seems that the second mark its the good one because, when i check with SLIC_ToolKit_V3.2 it still say 2.0, i think we skiped something,we only need acces to flash the second slic mark to succeed.

    I hope this help in someway & sorry for my bad english.

    Regards

    Hello guys, sorry for this newbie question, but I would like to insert SLIC 2.1 in this BIOS. It is a very old (2003) compaq desktop.
    Can please anybody give me a clue whether I can try to mod it myself or whether it is totally unmoddeable?
    Many thanks in advance!

    -Manufacturer: Compaq
    -Motherboard Model: Evo D310 Microtower
    -Bios revision: 3.18
    -Bios Type: Compaq

    On a Chinese website I found a bios version of the HP Compaq 6910p (F19, the latest) which was said to be edited with SLIC 2.1.
    I tried it on my 6910p and indeed it says 2.1 when I check with Everest.
    Could this be real, or just some textual change? With hex compare I see there are three places edited in the original. The two SLIC tables are changed and in the beginning of the bin file, a FF changed to FE.

    For the interested, I attached a screendump of the hex diff summary, showing only the differences...

    Could you please post a link to the modded one? Does it activate? How did you flash the mod? A patched flasher? That would be a breakthrough regarding HPQ bioses that have got two instances of a SLIC!!!
    At first sight you are right, the marker is updated at both SLICS and that magic byte...it works??? A rw everything report would be nice.
    Thanks.

    To find the sequence you can have a look at other bioses:
    07 FC 66 B9 9C F1 DD BE XX 00 63 FF FF 66 BF or more unspecific: (one hit only??)

    00 63 FF FF 66 BF
    To figure what it changes you would need to disassemble the code.

    Tested 3 bioses:
    66 B9 9C F1 DD BE XX XX XX FF FF 66 BF
    **EDIT** this sequence is crap it isn't related to ARPL command...

    This is it:
    00 63 FF FF

    Tried several bioses. Should match. One hit only.
