    This is exciting....I'm very curious if the direct edit method will work at 'double' SLIC bioses....

    No, but the module that contains the SLIC table (pubkey and marker) could have a checksum.....therefore to disassemble rompaq and figure how to calculate valid sums would be great....

    HP530 Success!!!!

    Tried and tested on a HP530 which did have slic 2.0
    The entry in the RSDT is a bit odd, SLIC_Dump tool reports the entry as "HP 30D5" but it activated non the less!

    Well done Hotpepper - have a virtual beer or 2 on me.

    Too bad, I was afraid of. HPQFlash DOES NOT update the SLIC at bioses containing 2 occurrences of marker....last chance is to patch rompaq or to correct the sums...

    Hi,

    so I think we figured out how to update a HP BIOS with just one SLIC marker in it.

    Next level is how to do that with a BIOS that has 2 markers in it.

    Absolutely right, I hope mutante can figure something about the sums, disassenbling / patch rompaq...

    HPQ-flash doesn't update....hmmm are there some settings to change...or switches--hpq flash don't start at my PC.....

    Ah yes.....if acpi revision = 2.0 and XSDT OEMIDs are matching to SLIC (I guess so) then RSDT OEMIDs could be different.....OK...rw-everything doesn't dump the XSDT for some reason....back to HP...thanks for the report...

    To be perfectly honest i am just happy that the method seems to work, i just hope it leads to an easier method for those not happy with doing this.

    Thanks to all you bios experts.
