hello all, i have been following this thread from start and would like to
test the firmware myself. i have some questions about flashing that i'm
hoping someone can answer. both my turbot boards currently have .090
firmware. in the past i have used a piece of hardware called SPI Hook by
tincantools and the software "flashrom" to flash my boards. i know the
flash utlity is available but i just enjoyed using the mentioned combo. up
to and including firmware 0.90 the file provided had extension .bin. since
0.90 all the compressed packages use file with extension .fd my questions
are 1. is the .fd file flashable with flashrom like .bin file are.?   2.
i've read i can open .fd file in hex editor and save as .bin and flash
that, is this possible to do without damage to board?   thanks for any
help. also if anyone has other suggestions on flashing the current file
from intel using flashrom i would like to hear.. thanks again. if it turns
out there is no path to using flashrom with the .fd files i plan to use
provided utility to flash and then join these tests. thank you.
