Greetings,

Here is a failure report against an Intel DX48BT2 motherboard which
uses a ICH9R and a Winbond W25x16 containing the BIOS.

Command I executed was:

./flashrom -c W25x16 -rV out.bin
 
flashrom v0.9.1-r889
No coreboot table found.

Any idea what is going on?  According to the W25x16 documentation opcodes
0x03 and 0x05 are supported.  OS is Fedora 12.
