    You meant the TCPA table? It becomes compressed! To compress doesn't mean to decrease the size because prepare also has to add the module header.:

    At rom.scr means: (to edit with notepad)
    COMPRESS LZINT (to compress any following module)

    parameter -X (disables compression)


    At a compressed module you cannot read the OEMIDs anymore like Lenovo cb-01 and TCPA

    If you re-run the edited rom.scr
    ACPI ACPI2.ROM -X

    and have a look at the new created ACPI2.MOD you'll see that the table remains original (header added only)

    To compress is a sort of 'encryption'

    thanks, i understand what all that means... i created the files :p, except rom.scr of course... it's there to show my command was correct

    I ask because I get this PBE error (attached pic) after I insert the acpi2.mod into the bios.
    It may have something to do with the size; rom.log says the size should be 4Bh. The compressed module is 4Dh. If this is the case, then it is a compression problem, right?, since I didn't add any bytes, just altered them?
    How do I insert the modified acpi.rom (acpi2.mod) into the bios without getting this error?

    thanks AGAIN :)
