Bad_Ad84 pointed out that itвЂ™s possible to power it from other legs on the chip вЂ“ so link up leg 2 to 13 (GND), and legs 43 and 44 to leg 23 (VCC).

ThatвЂ™s all the legs on one side completed :-) Finally itвЂ™s time to provide power and GND to the new chip. Work your way along, taking your time to do each leg. The red arrow is where I put my soldering iron to heat up the leg and the solder, I gently push it in the direction shown to push the leg down onto the pad properly. The photo above shows that IвЂ™ve completed the first 5 legs. Now do the other 2 corners and the chip will hold itself securely in place ready for you to solder the remaining legs. Make sure that the chip is completely straight and that the rest of the legs line up, then heat up and solder into place the leg on the opposite corner. Hold the chip in place and solder justВ one of the corner legs. I place the chip upside down, then with a drop of solder on the iron down, I touched each leg with the iron to transfer a small bit of solder to it.В You only want a tiny bit on there! Unfortunately I forgot to photograph that I added a tiny bit of solder to each leg. Now itвЂ™s time to prepare your new chip, straighten out legs 1, 2, 43 and 44. You canвЂ™t really see it too clearly in the following photo, but there is more solder there! If necessary, add a small amount to the pads, you donвЂ™t want lots on there though вЂ“ I do this by holding the soldering iron on the pad, and then just quickly touching it with some solder, you can easily control how much gets added to the pad this way by lifting the solder away when ready. The new chip is a tiny bit wider than the old, so make sure that the solder on the pads reach the end so that you get good contact on each leg you solder on next. You can probably do a couple at a time and then wipe them off on a bit of wet sponge. Very quickly run your soldering iron along each pad and the bit of remaining leg should come away with it. Now itвЂ™s time to tidy up the padsВ ready toВ solder the new chip onto. If this is the case, you can gently lever it off, be VERY careful not to damage the board if you have to do this, if possible,В use something plastic to do this, so you donвЂ™t scratch the board or damage any traces. You may find that the chip is glued to the board and wonвЂ™t just lift off. Work you way along both sides and double check them, you definitely want a clean cut through each leg for the next bit! In fact, TRIPLE check them.

I hold them with the flat side facing upwards so that the sharp edge is as far away from the motherboard as possible and then cut each leg as close to the chip as I can (youвЂ™ll probably find it will cut on the bend of the leg, thatвЂ™s perfect!) I donвЂ™t have a hot air station anymore, so I used a pair of half decent side cutters to carefully snip each leg. HereвЂ™s how I removed the existing BIOS chip (IC7 on the couple of boards IвЂ™ve looked at). You can also buy a pre-programmed chip from Bad_Ad84, making this a very very easy mod. For further details check out the the site which released it.Д«ad_Ad84 has pointed out that itвЂ™s probably easiest to get GND and VCC from other legs on the same chip, so вЂ“ link up leg 2 to 13 (GND), and legs 43 and 44 to leg 23 (VCC). Currently it does not let you play CDr discs or control video mode, but itвЂ™s still a fantastic achievement.
