The target volume’s free space is only 120 bytes. The NVMe driver requires 2048 bytes after alignment.

Always test your modified BIOS in a virtual machine (like OVMF with the same Aptio V version) before flashing hardware. The 4500023 error is a warning; ignoring it on real silicon can be costly. But with the right methodology, it’s just another step toward firmware mastery. Have you encountered a variant of error 4500023 with MMTool and Aptio V? Share your specific board and module details in a firmware forum—chances are someone has already found the exact volume offset to patch. mmtool+aptio+4500023

By learning to interpret free space, alignment, and volume signatures—and by using replacement tricks or alignment padding—you can successfully modify nearly any AMI Aptio V BIOS. The target volume’s free space is only 120 bytes
