Driver Lenovo L - ig41m2 v1.0

You left out the model number, but go to the page above, click Desktops, click ThinkCentre M Series, click ThinkCentre M57, click 6072, then figure out your model number and select that, finally select the operating system for which you need drivers.

The i in i915p, and i915g, stands for Intel.

It is a motherboard chipset made BY Intel, for IBM/Lenovo.
HOWEVER, just as you suspected, the drivers are proprietary from Lenovo.

Research has led me to conclude the Lenovo 29r8260 motherboard, was used in the IBM/Lenovo ThinkCentre M51; series of Desktop PC's.

Let's go see if this holds true, using the information we have.......

Intel 915G motherboard chipset

http://www.ebay.com/itm/IBM-ThinkCentre-M51-Motherboard-3-4GHz-P4-HT-29R8260-8143-WMG-/360578959486?pt=US_Motherboard_CPU_Combos&hash=item53f42e487e

So far everything looks good.
One more thing to check.........
Go to Device Manager, and see if Broadcom is listed; under -
Network adapters.

(Using WinXP as an example,
Start > Right-click on My Computer > Left-click on Properties at the bottom of the list.
Left-click on the Hardware tab > Left-click on Device Manager.
Left-click on the + sign next to - Network adapter)

Conclusion?
If Broadcom is the name of the ethernet chipset, it will be in the Network adapter list.
If this holds true, then the following Lenovo Support website, for the ThinkCentre M51 is the one you want,

http://support.lenovo.com/en_US/downloads/default.page?selector=expand

Using the Ethernet driver as an example;

1) Click on - Networking: LAN (Ethernet)
2) Click on the blue - [+] Click for files

3) Click on the blue - Broadcom Ethernet driver and software.
(Or Download, to the right)
4) A small window will come up -
Opening q3etn12us13.exe
Click on Save File.

5) A small download window will come up.
Allow the file to download all the way, then DOUBLE-click right on the file name.

At the bottom of the next 3 small windows, click on -
Next, Next, and Finish.

If you are not asked to restart your computer, do so.
Close all windows, go back to your desktop screen.
WinXP: Click on Start > Turn Off Computer > Restart.

I'm sure you didn't need all that, but included just in case.

For additional questions please post in a Comment, or on Reply at the end of the solution.

You will need to individually install the drivers from the Lenova website.

The same model ThinkCentre can have different types of network, video and audio drivers and unless you know exactly which one is installed in your ThinkCentre, you need to download all the drivers and install each driver until you find the right driver. When you download the audio and device drivers, write down the device driver and it's file name so you have a record of which driver you are installing and which directory the unzipped files are located on your hard drive. Go to the IBM/Lenovo WEB site - support/download page and download the latest Windows device drivers for your model computer, Use this link: - http://www-307.ibm.com/pc/support/site.wss/product.do?template=%2Fproductselection%2Flandingpages%2FbrowseByProductLandingPage.vm&sitestyle=lenovo&brandind=10&validate=true
