    Hi all,
    I Have this HP Pavilion DV2000 laptop. The Model states it is a DV2500 with a service Tag of DV2637TX.

    I wanted to put in a different WIFi adapter and discovered the wonderful world of whitelisted adapters, and the not so wonderful BIOS hacks.

    Being well versed with coding, Hex editors and the like, I followed a guide to enable the Wifi adapter I wanted. Looked all good until I flashed the BIOS and now the laptop is unbootable.

    I did a million searches and tried all the ways of accessing any type of recovery.

    I beleive the only way is to flash the chip or replace it. I do have a programmer to flash the chip, but what I need to know is what part of the official BIOS update I need to burn to the chip. I assume the software updater is an exe that has checks and the flasher along with the .bin rolled into one.

    I have seen some recent motherboards that seem to flash multiple ROM images, so I am uncertain exactly what to flash to the chip.

    Is anyone able to point to a guide?

    Also, what exactly is this laptop categorised under in the lounge list as I dont see anything that is really the same numbering. The DV2 is AMD nd mine is an intel 2.20GHz.

    Thanks alot

    UPDATE* I put the HDD into an external reader and found the BIOS backup I took before I flashed the modded one.
    Wondering if this can be burnt to the chip without doing it from windows. Remember the laptop is unbootable.

    I am about to unsolder the flash chip and read it. I intend to compare the dump with the BIOS backup and see if the backup resembles the dumped code. If so I will try to work out what needs to be flashed and give it a shot. I cant stuff it up any more than I have already!

    EDIT, flashed BIOS with backup code I cut from the BIOS backup. I have a tiny bit of work to finish off soldering the BIOS chip back on and can report after reassembly.
