i read with afuwin and then tried unmodified file afuwin.rom to write back. error 43 came up.
reboot
then read again. this is afuwin_def.rom
now laptop has graphic problem and does not start every time. stupid from me.
i can read / write chip with programmer if needed.

i tried writing and verifying its okay too.
can somone repair the dump or is there a clean dump? i would like to install last update offered from panasonic.

how do the chips work, sold on ebay? why they are selling with hardware and not only dump?

is it possible to extract bin from original panasonic update exe file? with starting update and looking in temp i wasnt sucessfull. 7 zip extracts some parts but not usefull in my sight.

Yes with panasonic bios extractor. https://www.badcaps.net/forum/troubl...26#post1622426
The bios update then needs further editing with a hex editor to remove a capsule/bios update header
