Top Solution #1: Use the Correct MMTool Version

Resizable BAR (ReBar)

: Enthusiasts use this tool to add ReBar support to PCIe buses on older hardware, potentially improving GPU performance. Extract correctly: Use AFUWINx64 /O (backup original) rather

Part 1: What is MMTool and Aptio V?

• Extract correctly: Use AFUWINx64 /O (backup original) rather than a sketchy download.
• Check file size: The file must be an exact multiple of 0x1000 (4096 bytes). Use a hex editor (HxD) to see if the last few bytes contain 0xFFFFFFFF or valid data.
• Test with UEFITool: Download UEFITool NE (open source). If UEFITool opens your BIOS without error, the issue is MMTool-specific. If UEFITool also fails, the file is corrupt.

Platform Support:

Optimized for Aptio IV (Intel 6/7/8/9-series or X79 chipsets).
