65List the ROM chips, chipsets, and mainboards supported by flashrom.
66The list of mainboards consists of those boards which need a special
67ROM write-enable function for flashrom to work.
68.sp
69There are many other boards which will work out of the box, without such
70special support in flashrom. Some of the known-good/known-bad and tested ones
71are listed at
72.BR http://coreboot.org/Flashrom#Supported_mainboards ,
73but the list is not exhaustive, of course.
