    hello,

    As you can see the method for flashing HP bios is under development.
    You have to wait, sorry.
    Come back in few days, who knows.

    regards

    Can someone please clear something up for me? Based on the above quote, if an HP BIOS (laptop in my case) uses WinFlash to flash the BIOS; then there is no problem with checksums etc. Is this correct or no? The reason I'm asking is that I have an HP Pavilion dv9543cl laptop that comes with SLIC 2.0 and uses WinFlash to flash the BIOS. I would like to flash it with a BIOS modded with SLIC 2.1.

    Of course a one click soltion is better. But at the moment there's no way to get it. You'll have to wait so far...

    Try it. I have NEVER done things like that before, and it went well for me. - Only, HxD HAS to be started as Administrator. :)

    We know that the flash tool writes 14 banks and at bios bakup it backups all 15 banks. HP itself must write the 15th bank to update to SLIC2.1 officially...how do they?

    -special rompaq program (I'm afraid, I don't think so..:( )
    -a update flag set somewhere, at biosfile, at EEPROM?????

    mutante, is there a way to patch rompaq to update all 15 banks?

    I tried patched rompaq_.exe from sp39427 with ORIGINAL 68MAD:
    rompaq_.exe /U (banks 1...14)
    rompaq_.exe /B (banks 1...15)
    rompaq_.exe /R (banks 1...14) with original 68MAD.BIN renamed to 68MAD.BAK
    Code:
    The code used to verify the integrity of your BIOS does not match
what is currently on your system. This could cause parts of the BOIS
to be skipped when updating leading to unpredictable results including
failure to load. It very strongly recommended that you not proceed with the update.
Press
F10=Continue, ESC=Cancel
    I draw your attention to the fact that there are two ways to update the BIOS with a rompaq_.exe, I mean Update (/U) and Restore (/R with modded 68MAD.BIN renamed to 68MAD.BAK ) modes.
