    I was unable to read correcty smaller ic (XM25QH64A) with ch341 with neoprogrammer or colibri
    Only QH128A was readed correctly.

    Allowed flash chips are recorded in the VSCC table of the descriptor region.
    Descriptor region is in the smaller chip, so nobody can answer your question.
    Also nobody can repair your bios in half. The whole bios dump is divided in parts between the two bios chips, so both parts must be present for repair to happen. And the repaired dump must be recorded back at both bios chips.

                Post more 16MB chip, what do you want us to do with an incomplete bios file ?
                Preferably 8MB file is also unedited files.

                                Hello,

                                i have still problem of two same laptops - still no service tag manufacturing mode.

                                ...tested 1st boot - bios setup, disabled absolute, stag filled , saved reboot.
                                ...2nd boot alt+f doesnt not work because because stag is again missing

                                What now?
                                Will be possible to write service tag manually in hexedit?

                                Thank You

                                        Get the bios update from dell support, extract it with PFS extract, you`ll find it on the forum if you search for it.The 16MB file is a full bios region, (1 -- 1 System BIOS with BiosGuard v1.xx.x.bin) ,flash that to the 16MB bios chip.

                                        .
