    I'll try it. It's kinda hard to get the BIOS version when it doesn't even get to the BIOS post sreen. Any suggested software that can get me past the startup-up password? If I can get the machine to get to boot from external media; I fell I can get it licked.

    Just a thought...
    I tried once to reset everything on an Inspiron 6400, try this. Do a bios recovery!, I believe you need to extract the *.hdr file, rename it 1545A14.HDR (not positive about the exact name it is supposed to be) and put it on a fat formatted usb stick - no need to make it bootable. unplug the laptop, remove the battery. put the usb stick in, press the end key, then the power key. then plug it in. (I think from memory that is the sequence, if you want to try this I can confirm all this) The power light should flash red, release the end key as soon as it does, wait a few minutes, it will search for usb sticks, search for the file, read the file, flash and just to be certain it recovers it will reset every stored setting including passwords.

    BEA14.HDR should be the filename BE?à.0BIN... HDR

    my inspiron 1520 is CORA09.HDR = COR?à.0BIN... HDR

    bludgard,

    From the bios itself, here are all possible file names for the HDR file, The ??? are wildcards, I suppose any value may work. I always used to use the last four from the original file (as long as they were alpha-numeric), but have no idea if it made any difference! I suggest putting multiple copies in the usb stick, using every format listed, at least you can rule out file name as the culprit if it doesn't work! I would disregard the *.BIN names and stick with the HDR. I imagine the bin files would be the rom files but cannot confirm that and it is irrelevant anyways.

    Code:
    Offset      0  1  2  3  4  5  6  7   8  9  A  B  C  D  E  F
    
    00002FB0                                           52 4F 42                ROB
    00002FC0   45 3F 3F 3F 3F 42 49 4E  00 52 4F 42 45 3F 3F 3F   E????BIN ROBE???
    00002FD0   3F 48 44 52 00 52 4F 42  45 3F 3F 3F 3F 48 44 43   ?HDR ROBE????HDC
    00002FE0   00 31 35 34 35 3F 3F 3F  3F 42 49 4E 00 31 35 34    1545????BIN 154
    00002FF0   35 3F 3F 3F 3F 48 44 52                            5????HDR
    Just to be clear, this is for an Inspiron 1545 and the file names should be ROBE????.HDR or 1545????.HDR where you do not use the "?" but rather an alpha-numeric value, therefore the names could be ROBEOA14.HDR or 1545OA14.HDR I got these values from the 3B_41.ROM that I used Andy's tool to decompile from the A14 bios version.
    Here is a link to bios recovery instructions. I was wrong about the power button, you only need to remove the battery and power cable. put the usb key in with the appropriate file. Press and hold the end key, plug the power cable back in, the power led should be red momentarily, release the "end" key while it is red and it will search any FAT32 formatted usb stick for the appropriate file.

    sometimes power button is needed if bios not corrupt. depends on model.


    1545A14.HDR no O i believe or maybe that takes place of _ .. but dont forget the . before HDR that counts also
