Mmmm BIOS mods they can be great fun and a mighty pain in the ass. What has y'all experience been with such a thing? I just softbricked the bios on my lan machine so I had to pull out the old SPI Programmer to fix it.
What sort of modifications have you done to your motherboards BIOS and what would you like to see done in the future?
`./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -w IMB181L1.80 -V
flashrom v0.9.9-r1955 on Linux 4.1.25-ti-r62 (armv7l)
flashrom is free software, get the source code at https://flashrom.org
flashrom was built with libpci 3.2.1, GCC 4.9.2, little endian
Command line (5 args): ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -w IMB181L1.80 -V
Calibrating delay loop... OS timer resolution is 6 usecs, 499M loops per second, 10 myus = 11 us, 100 myus = 193 us, 1000 myus = 999 us, 10000 myus = 10083 us, 24 myus = 25 us, OK.

Found Winbond flash chip "W25Q64.V" (8192 kB, SPI).
This chip may contain one-time programmable memory. flashrom cannot read
and may never be able to write it, hence it may not be able to completely
clone the contents of this chip (see man page for details).
