OK I broke the darn bios chips in trying to reprogram them on my Gigabyte GA-H97M-D3H . The bios chip is MXIC 25L6473 . They are kind odd I guess everyone want a brick of gold for them. The question is can I use different bios chip that I can order on line for a whole less then 7.00 or 8.00 apiece.

@rodtoo40 - Broke them? How did that happen, squeeze too hard with clips and crush the legs? That always worried me

Yes, MX/MXIC Macronix always cost more than Winbond, not sure why, maybe better quality? These are all the flash ROM ID's in the VSCC table within the BIOS/ME, all would be compatible by default

1F4700h = 1F4700: Atmel AT26DF321 / AT25DF321A
EF4017h = Winbond W25Q64 - W25Q64FVSIG <<< this is a common one I know, so didn't have to look up, commonly used on motherboards - this is what I use all the time for recovery, testing etc, very common and almost always works for any modern board with 8MB BIOS
5pcs $2.80 - https://www.ebay.com/itm/123223245280

C22017h = Macronix MX25L6405/6408/6445 <<< Your default BIOS - 5x for $5 here https://www.ebay.com/itm/171253385849EF3017h
Also, all these match same ID - MX2525L6405, MX2525L6405D, MX2525L6406E, MX2525L6408E, MX2525L6433F, MX2525L6435E, MX2525L6436E, MX2525L6439E, MX2525L6445E, MX2525L6465E, MX2525L6473E, MX2525L6473F, MX2525L6475E

EF6017h = Winbond W25Q64FW - 1.8V
EF4018h = Winbond W25Q128FV / W25Q128BV
C22018h = Macronix MX25L12805/12835/12845
EF6018h = Winbond W25Q128 - 1.8v
C84017h = GigaDevice GD25Q64 / GD25Q64B
