Good afternoon gentlemen, I have been working on getting a windows 7 activation for my Y500 for a few days now. It came with windows 8 (lol) but that doesn't really work for me. I need the UEFI boot mode for the dual boot setup I am running, so Daz's loader was unfortunately out of the question. After playing with WINDslic for a while I saw that was not the way to go either. I finally settled on modding my bios and inserting the SLIC table. I already had a modded bios flashed which enabled my Atheros wifi card which is blocked by the bulls**t whitelisting that Lenovo likes to do. This limited the ways I could add the SLIC (if you don't understand why, just ignore it. far too long to explain.) I was able to inject a SLIC while booted into windows using RWeverything, but the bios flashing I was doing simply WOULD NOT write to the SLIC section of the ACPI table. After digging through MDL stuff, I found the marker set tools, and after long and agonizing hours of constant rebooting...I present to you all the ultimate Lenovo Y500 bios flash toolchain. This will upgrade your bios to 2.04 (which fixes SLI issues), remove the hardware whitelist, and inject my SLIC2.1 all in one shot. Just make a bootable flash drive with the included tool, copy over the files from the contents folder, and reboot. Type in "GO.BAT" and watch the magic. ONLY FOR LENOVO Y500. This has the added ability to turn a $2,000 laptop into a paperweight. If you try to use this with anything other than a Y500, you will achieve that. Works on MBR and UEFI systems.
