 Did not know where I should put this but the bugtracker seemed like the
 right place.

 I tried flashrom and it could not detect my chip on my ASUS P5ND2-SLI
 Deluxe motherboard. The board has a SST49LF004B flash chip and after
 enforcing the right chip flashrom seems to work fine.

 # ./flashrom -V -f -r -c SST49LF004A/B test
 Calibrating delay loop... 796M loops per second, 100 myus = 201 us. OK.
 No coreboot table found.
 WARNING: No chipset found. Flash detection will most likely fail.
 Probing for SST SST49LF004A/B, 512 KB: probe_jedec: id1 0x21, id2 0x5e,
 id1 parity violation
 No EEPROM/flash device found.
 Force read (-f -r -c) requested, forcing chip probe success:
 Probing for SST SST49LF004A/B, 512 KB: Found chip "SST SST49LF004A/B" (512
 KB) at physical address 0xfff80000.
 Force reading flash... done.

 This should probably apply to the P5ND-SLI board, too.

 What do you need from me for adding autodetection of this board/chip?
