DIY eGPU Setup 1.35 is menu-driven versatile software that ensures your eGPU is configured and functions optimally.  Some systems cannot use an eGPU without it. Typically, required if you:

• encounter Windows error 12:cannot allocate resources
• want to set PCIe 1.1 Gen1 (2.5GT/s) or PCIe 2.0 Gen2 (5GT/s) link speed (2nd-gen i-core or newer CPUs).
• require ability to detect your eGPU in a pre-boot environment
• want to load a DSDT override without engaging Windows test signing mode
• want to disable a dGPU in a hybrid graphics system to free up resources to host the eGPU
• want to disable a dGPU in a hybrid graphics system to activate NVidia Optimus and if using a x1 link, engage x1 pci-e compression
• want to initialize a NVidia video card prior to Windows boot to prevent hang/BSOD on startup or error 43 in device Manager. Eliminates the need for a standby, attach, resume to overcome this problem.
• want to use x1E/x2E/x2/x4 higher performance PCIe links (core2duo and 1st gen i-core CPUs only)
