Re: RT809H ISP programming for laptop bios.
Hi
Desoldering bios chip, in my opinion, is the best option. You connect only "this one" and You read/write software directly from/to this one.
RT809H is very good and useful for programming not only KBC and bios chips (ChipProg-481 seems too), but for effective work - desolder "it" :-))
CH341A programmer offers "on-line" programming bios chips too, but sometimes what You
see is not what You want when connected to the mainboard.
Good luck
