Because DIY eGPU setups are highly specific to your laptop's BIOS and motherboard layout, the best place to find the latest "135" links and customized scripts is . This community maintains a massive database of "build guides" for specific laptop models.

Popular choices include the ADT-Link R43SG (for M.2 slots) or the EXP GDC Beast (for mini-PCIe/ExpressCard).

A standard desktop ATX power supply or a Dell DA-2 220W adapter to power the GPU.

A DIY eGPU setup allows you to connect a full-sized desktop graphics card to a laptop via an expansion slot. This is typically done through a Thunderbolt port, an M.2 NVMe slot, or an older mini-PCIe slot. The "135" often refers to specific driver versions or setup scripts, such as the DIY eGPU Setup 1.35 software, which is a popular tool used to bypass "Error 12" (insufficient resources) on older Windows systems. Hardware Requirements

Run the setup script in Windows to create a bootable entry.

The "Setup 1.35" software is a bootloader-based tool designed by developers in the eGPU community (often found on forums like egpu.io). It is used primarily to manage "PCIe Compact" issues.

Plug the eGPU adapter into the chosen slot.

This is the most common issue. It means Windows cannot find enough free resources for the GPU. Use the Setup 1.35 tool to perform a DSDT override or PCIe compaction.
