yes, very likely.

What do you mean exactly? The interface type is noted in the wiki table
as well as in the output of flashrom -L. For the chip in question on
that nforce2 board i think it would not make any difference anyway if
you would modify the bustype field in flashchips.c.

In theory that is possible, but normally the pin is connected to a
software-controlled pin (GPIO pin of the southbridge for example), and
you are way better off controlling that pin with flashrom (a
so-called board enable), than physically modifying a board.

when we type flashrom -L, we get:

...
MSI             MS-6787 (P4MAM-V/P4MAM-L)          OK      msi:ms6787
MSI             MS-7005 (651M-L)                   OK      (autodetected)
MSI             MS-7025 (K8N Neo2 Platinum)        OK      (autodetected)
MSI             MS-7046                            OK      (autodetected)
MSI             MS-7061 (KM4M-V/KM4AM-V)           OK      (autodetected)
...

i was thinking about adding column about packing/type of bios memory ie:

MSI    MS-7030   OK   (autodetect) PLCC32/LPC

or even some comments about this one. or link to report (this should be
enought readable.
in my case, i was looking for motherboard to program exactly one type chip.
it is not easy to look for mobo photos on google to find out which type the
chip is.

and in this case - i found plcc32 but wrong type.

i do prefer using flashrom's control - its easy and fun ;)
but with my mobos (as i reported few not working and being ready to help
find out how to enable it*)
i dont really care about them - it can be damaged throught this proccess or
not.
so i can try if it is impossible to 'enable' it.

*i can give You access throught ssh and leave those pc's powered on - but
it is for another topic.
