 Flash device is detected as a Winbond W39V040B device.  Flashrom attempts
 to flash device, but verification fails.  No actual writing to the chip
 appears to be done.  Tried changing write and erase in flashchips.c to:
 jedec, winbond_fwhub and 49lfxxxc.

 ./flashrom -wv xxxx.bin
 Calibrating delay loop... OK.
 No coreboot table found.
 Found chipset "Intel ICH7/ICH7R", enabling flash write... OK.
 Found chip "Winbond W39V040B" (512 KB) at physical address 0xfff80000.
 Flash image seems to be a legacy BIOS. Disabling checks.
 Programming page: 0007 at address: 0x00070000
 Verifying flash... FAILED!  Expected=0xc7, Read=0x49
