Remediation steps

• For modern Windows where 16-bit support is required:

  DMA-Based Memory Access: It enables direct memory access (DMA) via hardware like FPGA devices, allowing for high-speed memory acquisition and analysis without relying on the target operating system's kernel. Title: Demystifying vmm
