    @tormoz

    Are you sure if there is a whitelist in this machine, what is the error message when you insert a "non authorized" wlan card.

    I try two wwan 3g cards (hp un2400) and system not boot. Black screen and nothing happen. But if I insert card on running system (hot plug) it work correct.

    hello,

    i will not have time to have a look to this bios tonight, but keep in mind that Wlan cards are PCie and WAN card are USB with different connexion.
    and replacing a Wlan ID by a WWan id is something strange, whitelists (when exist) are in separate places and manage by different algorithms.
    regards

    first modifying a bios doent concist to delete modules.
    second you will not be able to flash it with insydeflash
    i've already spend a lot of time to trying to mod dumped bios with no success, i'm still working on it but it will take a while.

    hi greg, were you able to get the dump properly? what software did you use to decompress the binfile you have extracted? any tips? i am in the same situation that i want to use an external programmer to program the 25q16

    thanks

    there are two way to dump bios : fist via insydeflash program that comes with bios from HP site, you have to edit platform.ini file (all parameters well documented ) to enable "options" button ([option] section set flag=1) when it dupms bios , it dumps old bios and new bios just that size that flash IC needs. second way to dump it via programmer. there is a way to decomress bios it becomes 4mb filesize, but i don't know how to compress it back right. only way for me now to edit bios, when you dump it you need to open it with ezh20 program( the thing is that when this program open the bios it knows how and it does decompression bios into memory and when it save file it compress back bios right way ) then run WinHex and open ram (task ezh20) there you can see uncompressed bios image which you can edit directly in memory and then when you save file in ezh20 it saves with you modifications and then you can flash this moded file with programmer only
