-now look between solder points M and N and you will see a 040 on what i think is the bios chip. does this mean the "no gap" version of v4 is actualy v4 R?
-another note, maybe nothing, but on the flipside of the board there is also a chip much the same size with a stamp of "D 011 030 16M", the 030 is what caught my eye. I read something, somewhere about the U5.. 1C being the first in a series to have an anti-something or other, but for the life of me, I can't find the source again. Heard anything along these lines?
