    Alternate way to do the VFSB mod for the Abit AS8.

    I didn't come up with this mod myself, it was with help from 2 of the better volt modders around here, that came up with this idea for me, I was just the helper monkey willing to risk my board for a easier way to do this particular mod.

    I did it a few weeks ago, and just havent had a chance to get a good picture of it, to show how it was done.

    with this way, you need no soldering or a extra resistor between the two solder points, just solder to the 2 points shown, and ground it with the 3rd leg to the extra hole, that happens to be blocked by the IDE port...

    anyways, I know the pics aren't perfect, but they are all I can get.
    I had to borrow my friends digital camera, and this was about as good as I could get these pics, hopefully, people can get a better idea on how to easily do this mod.

    I used a 5K VR on this mod.
    that not nearly enough at all.
    if I were to redo this mod, I would try it with a 100K atleast.
    see, this mod is insanely sensitive.
    at first it will look like it's not doing anything...
    then you will come to a point where 1/8th of a single turn will take you from 1.23 volts, to 1.73 volts almost instantly.
    that one 1/8th tiny turn is extremely sensitive, and can adjust your voltage extremely fast with the 5K.

    oh yeah... the mod is also backwards...
    meaning, counterclockwise for more voltage, clockwise for less...

    it's abit of a weird mod, but once you get it right, it's nice to have such a range for your VFSB Voltage.
    I have had it up to 1.75 volts with no problem.
    even had it up to 2.0 volts by complet accident...
    but then the motherboard doesn't boot, if you reboot.
    so somewhere around 1.7 volts, the mod will make the motherboard stop booting, in which case you need to turn it back down (clockwise) for less voltage.
