Lenovo Y410p / Y510p - unlocked BIOS / wlan whitelist mod / vbios mod
markymark69 replied to svl7's topic in Lenovo
Hi, Ive been watching this thread for a while. Any word on when an unlocked (not just whitelisted) BIOS for 2.07 will be out? I can provide a dump if nessacary. Cheers -
I got to the Darwin bootloader on my Y410P ( GT 755M) with OS X Mavericks Retail. However, I cannot get past this step, it throws a few error messages clearly related to my graphics card, "Failed to inject NVIDIA" and some hex error codes. I can see It load the kernel and other boot files when using the -v -x -f flags but the screen goes black and the computer restarts. Apparently they dropped basic VESA support from the bootloader in editions >= Mountain Lion that in the past has enabled people to get past this step and thru installation after which they can use Multibeast to handle kexts etc that our cards require. I wonder if I could use the unlocked BIOS to default to the HD4600 or at least disable the 755m until after installation.

Switching between 750m and 4600m on the y510p when unplugged

The option to switch between GPUs is in Nvidia Control Panel (at least on the most up to date version). In the left hand column under "Manage 3D Settings" you can choose to "Auto-Select", "High Performance NVIDIA processor" or "Integrated Graphics" -
From what I understand OS X dosen't use "optimus" but instead has its own proprietary version of graphics hardware switching software built in to the OS.
