Nope :-( Found a HP document with the following text: "The HP BIOS uses hardware mechanisms on most HP Business Desktops to prevent access to the BIOS flash memory by any software other than the BIOS. This hardware traps any attempts to update the flash memory that do not originate from the BIOS itself. BIOS images that work with HP Windows-based BIOS update tools (flash tools), such as HPQFlash and SSM, contain a digital signature that allows the flash tools to authenticate the BIOS image. This ensures that the image originated from HP and has not been corrupted or tampered with in any way." Which seems to confirm what Michael stated earlier. -mattias _______________________________________________ flashrom mailing list [email protected] http://www.flashrom.org/mailman/listinfo/flashrom
