This paper explores the feasibility and methodology of archiving and running the Microsoft Windows 98 operating system using the QCOW2 (QEMU Copy-On-Write) disk format. While Windows 98 is legacy software designed for IDE mechanical hard drives, modern virtualization requires specific configurations to bridge the gap between legacy BIOS expectations and modern QEMU hardware emulation. This document outlines the creation of the disk image, the installation hurdles, and critical performance optimizations regarding video and input latency.
