The software for the flash was a bit different and I had to do a little research for a workaround for windows (I bought a cheaper Chinese flashing usb dongle.) but over the next few days I can compile some print screens and a basic write-up of what I did.

Perfect Wink thanks friend !!!

So I have a rough draft for the steps. Tell me if there's anything else I should include. I'll need to pretty it up a little but this is what I have at the moment.

http://www.ebay.com/sch/i.html?_trksid=p...Test+Clips&_nkw=SOIC8+SOP8+flash+chip+IC+Test+Clips&_sacat=0&_from=R40


Flashing your BIOS with hardware.

Step 1.
Obtain a modified bios.
* The community is ready and willing to help you with this. If you don't have the skills, you can do what I did and ask for a modified bios. Use the proper system that is already set to request a modified bios. [insert link here to template]

Step 2.
Purchase the necessary equipment.
* For my bios chip I needed a CH341A programmer and a SOIC8 SOP8 test clip. (Found them on ebay, it cost me a total of $20 for both items.)

Step 3.
Download the drivers and software for the programmer you purchased.
* (The drivers and software for the hardware I purchased were located on the seller's ad page on ebay.) This step should usually be completed BEFORE plugging the programmer to your computer. Installing them before plugging the programmer into your computer will help avoid potential driver trouble with Windows. (I had some trouble installing the drivers and had to Disable "Driver Signature Enforcement" as the drivers were not digitally signed Looking back on it I maybe should have used a virtual machine but... oh well.]) After installation, reboot your computer.

Step 4.
Plug in the programmer into your computer and run the included software.

Step 5.
Identify the bios chip on your motherboard and secure the clip onto the board.
* This was kind of difficult for me. I looked up a schematic of my motherboard to find out where it would most likely be located.

Step 6.
This step will be based entirely on the software that came with your programmer. I will show the steps involved in the software that came with mine.
* Either enter in the exact chip information or, if the software you're using has an auto-detect option, you can use this, but I would recommend double checking. I went the lazy route and just went with the auto-detection. It worked well enough for me but I don't recommend relying on it.

Step 7.
Read the chip.
* Read the current programming on the chip and make some comparisons to the original bios. This can be done with a Hex editor. Just make sure that it looks almost exactly the same. Remember, they should be the same file just with a few edits so they should still look almost identical.

Step 8.
Load the modified bios file and write it to the chip.
* After loading the modified file, the tools I used only required I click an "Auto" button. This then took around a minute or two to write everything to the bios chip. If the program freezes, or appears to be doing nothing, don't touch anything for the next 10 minutes as you don't want to mess anything up if it is doing something.

Step 9.
Remove the clips and see if your laptop boots.

I also have some pictures of the process but still need to take a few more tomorrow.

What are your thoughts?

I honestly don't know very much about flashing chips but I was asked to make a guide on how I succeeded in flashing a modded bios from this forum to my laptop bios. I do not take responsibility for any damage done to your device if you followed this guide.

Hey guys, does anyone know how to find a schematic of a Lenovo P500 so I can locate the bios chip on the motherboard? I have to flash a corrupt bios.

I've done a little searching and it looks like it might be one of a couple different board types. 
Look on the left side of this image where it says VIWZ1_Z2 LA-9061P
http://partsexpert.com.ua/content/images...791817.jpg

Look on your motherboard where it says LA-9061P in the picture and do a google search for what's written on your board. 

I did a quick search www.google.com/search?q=LA-9061P and found this http://kythuatphancung.com/uploads/downl...-9061P.pdf 

If your motherboard was the LA-9061P, if you look at the schematic, on page 2, it shows the bios (SPIROM BIOS) hooked into, what would have used to have been called the south bridge [I'm going to call it the south bridge from now on because I don't know what they're calling it these days.](The Intel Panther Point chip). If you look at this picture of the motherboard from the top http://partsexpert.com.ua/content/images...small2.jpg. You can see that you have the CPU in the center, and 2 other big chips. The one on top is likely the graphics core and the one on the left is likely the south bridge. (I'm guessing the one on the top is the graphics card because of the long memory chips next to it as a GPU typically will have memory chips very close to it.) So if you look around the southbridge you'll see several chips that could be the Bios chip. Unfortunately I simply took a guess as to what chip was my bios and I was right. You may need to take a picture of the chips in that area, or even take a picture of your motherboard, and post it on the forum here. I'm sure if you posted a few good quality pictures, someone on this forum would be able to point out your Bios chip.

Edit* I am an amateur when it comes to doing this sort of thing. Most of my instructions are based on my experience which is very limited. So, please, take this with a grain of salt.
