Hi,
flashrom cannot work on Intel ICH7/ICH7R / SST SST25VF016B (2048 KB, SPI). MB: Supermicro X7SLM-L / http://www.supermicro.com/products/motherboard/Core2Duo/945/X7SLM-L.cfm
The outputs of 'flashrom -V', 'lspci -nnvvvxxx', 'superiotool -deV', 'dd if=/dev/mem of=sm_x7slm.system.rom bs=64k count=1 skip=15' are attached.

Hi,
According to the Device Operation Instructions in page 8 in SST25VF016B datasheet (http://www.sst.com/dotAsset/40371.pdf), I modify OPCODES O_ST_M25P as below. Then flashrom can flash BIOS successfully. Can someone check if any problem or side effect to other boards?

Cool. Nice work. I think that Carldani might be able to tell offhand what effect this has on other chips.
