In a remarkable feat of retro computing, a YouTuber known as Omores has successfully booted Windows 98 on the modern Ryzen 9900X CPU. This endeavor not only showcases the capabilities of contemporary hardware but also highlights the enduring charm of vintage operating systems. The project required a series of thoughtful modifications and technical adjustments to bridge the gap between decades of technological advancement.

While this isn’t the first instance of a retro Windows OS being run on modern hardware—Omores previously booted Windows 2000 from an NVMe drive—this latest achievement stands out due to the powerful specifications of the Ryzen 9900X, which boasts a base clock speed of 4.4 GHz. The journey to success was not without its challenges; initial attempts were met with failure, prompting the YouTuber to explore various solutions.
Recognizing that the high clock speed of the Ryzen 9900X could be a hindrance, Omores made several BIOS tweaks in hopes of achieving compatibility. However, these adjustments did not yield the desired results. Drawing from past experiences with installing Windows 3.1, the YouTuber recalled that utilizing a PCI SATA card had resolved similar issues. This strategy proved effective once again, allowing Windows 98 to communicate with the modern system.
The PCI SATA card, equipped with its own BIOS, successfully bypassed the contemporary SATA controllers present on the Asus X670 Prime AM5 motherboard. To facilitate this connection, a PCIe-to-PCI adapter was necessary, given that the motherboard exclusively features PCIe slots. Additional modifications included disabling the Advanced Configuration and Power Interface (ACPI) and employing BIOS Flashback. Furthermore, a Gen 5 NVMe SSD was utilized for storage, with a crucial stipulation: the partition had to be limited to a maximum of 8.5 GB to ensure compatibility.
The culmination of these efforts resulted in a successful boot of Windows 98, leading to an impressive demonstration of the operating system’s capabilities. In a notable test, Omores ran 3DMark using retro graphics cards, such as the GeForce 7900 GS and ATI X700LE, achieving surprisingly strong benchmark results. This project not only revives nostalgia for the computing era of the late 90s but also exemplifies the innovative spirit of tech enthusiasts who continue to push the boundaries of what is possible with both old and new technologies.
