Do you know if the X800 has the ROM lock "feature".  Thomas Perrier's
site seems to be specific to the R9800.  I have a few X800/X850s
kicking around I've been meaning to convert.  I thought all I'd need
to do is replace the flash chip.  If this ROM lock thing is on that
card too, I can see where that would have been just an exercise in
frustration.

It's too bad that themacelite's forums went down.  There was some
great information in there.  Do you know if there's an archive
available?
