You need a chip with the same capacity and same electrical characteristics, i.e. __access time and voltage level__. You can look for this information in the W39V040B datasheet. I think Winbond also provides a cross-reference documentation that list the compatibilities of their flash ROMs with flash ROM produced by other manufacturers. I'm not sure if SB600 can decode the R/W access to Flash ROM bigger than your current flash ROM. Maybe others can clarify? >> >> > superiotool r3511 >> > Found ITE IT8726F (id=0x8726, rev=0x1) at 0x2e >> > No dump available for this Super I/O >> >> Nice, first board with ITE IT8726F we've seen so far.
