Hi all.

These are the changes I had to do the flashrom to get my in circuit
programer working. Not much as you can see.

Unfortunately it seems to have problems writing to the chip. The first
time I tried it it worked well. Writing random data to the chip. But
when I then tried to write the bios image. After several tries, adding
more capacitors, increasing the bus speed (yes increasing not
decreasing) and always erasing the chip before doing a write I got
good write. There where a couple of write runs that seems to be get
partial success, parts of the bios looked okay while parts where still
all FF. Increasing the bus speed seemed to make it write more data.

I have some pictures of the programer here:
