    HP Compaq NC6000 whitelist removal

    Has anyone come up with a working whitelist removal for HP Compaq NC6000? I have read that this is a somewhat problematic BIOS. Can it be restored with a USB floppy? Cheers

    Has anyone here ever successfully been able to build a SLIC 2.1 bios for the HP/Compaq DC5000sff? I've got several of these and would really like to get them going on 7.

    Hi TTAV134, could you please help out with the following?:
    I tried "HP Compaq nc8230/nx8220/nw8240 Notebook PC (version F.18 24-jul-2009) whitelist removed" (from post #1107 21 Oct 2010, 02:44 AM) on nc8230, and there are a couple issues with this:
    1) it looks like it's actually F.17 from 2008 and not F.18.
    2) the modded version does not appear to have SLIC2.1 in it (tried to use rweverything and aida extreme to confirm).

    Also, quick question, once the SLIC2.1 is inserted into this bios, and it's flashed, is HP-COMPAQ.xrm-ms from the "The Official Windows 7 Repository" the right certificate to use?
    Thanks.

    Great, but what does it actually work on?
    Desktop only? Which ones?

    How about the other way? Compressor as well?

    HP Compaq Business PC decompressor

    This is only to be used on HP Compaq Desktop Business PCs... Hehe, a compressor wasn't in the ROM image.. This is only a decompressor. Feel free to use OllyDebug on the code and learn :) It uses a dictionary technique.

    I had the code a long time but only for real mode addressing, put in a .COM file.. And now, here it is, fully Win32 capable :) Enjoy, happy XMAS. This tool is dedicated to x7a & my daddy ;)

    No compressor for now, I'm sorry.. Hope you like my hard work.

    HP Compaq Business PC decompressor

    Try googling for 'business compaq 786' and choose your bios from Google autocomplete. My tool decompresses these bios models. If you choose the Windows 7 version of a particular 786 bios, and use a hex editor on the output ROM files, you can find a SLIC table ;)

    Damn me if it doesn't work ;) And for releasing it anyway.

    HP Compaq BIOS Decompressor

    I tested it on HP Compaq Business Desktop dc5000 and dx2000 System BIOS (786B0 BIOS), and 786B2 BIOS. The Rom.Bin size needs to be only 512kb.

    I am sorry, but it is really pointless effort (thanks anyway)

    HP Compaq Business Desktop dc5000 series
    HP recommends Microsoft® Windows® XP Professional

    HP Compaq Business Desktop dx2000 microtower
    HP recommends Windows® XP Professional

    Would they be really worth anything at all under Win7?
