Hello

I've been trying to flash a Macronix MX25L12873F chip on a Lenovo IQ2X0IH board. I aquired a bios through vinafix.com.
I tried flashing with flahrom and a CH341a programmer but flashrom detected chip "MX25L12805D" or "MX25L12835F/MX25L12845E/MX25L12865E". I selected one of those options, even though it wasn't my chip and the flashing was succesful. I tried it and it booted one time perfectley but stopped booting afterwards.
I then read on the flashrom supported hardware page that that chip was not supported. So I tried with the windows programs: Ch341a v1.34 and AsProgrammer 1.4. The chip is identified, erased, and written, but fails on verification and of course, does not load.

Any help would be appreciated.

Thank you

Keep trying other tools/version and dont loose time flashing/booting if NO verification is valid.

1.8v chip

@MeatWar Thanks. I'll check that out. Why 1.8V? I thought it was 3V
