  • Modern laptops like the 2020 Thinkpad X13 Gen 1 can still run MS-DOS 6.22, a 30-year-old OS.
  • UEFI Class 3 devices, introduced in 2020, no longer support legacy BIOS, breaking DOS compatibility.
  • Lenovo's 2020 Thinkpad models (Intel variants) still support UEFI-CSM, enabling DOS to run natively.
  • SBEMU provides Sound Blaster compatibility for modern audio hardware in DOS.
  • Network adapters like Realtek 8125, Broadcom BCM57, and Intel I-210 can be used in DOS via Thunderbolt.
  • Benchmark tests show DOS performance on modern hardware, including games like Doom and Quake.
  • Thunderbolt support in DOS is unexpected but works due to PCIe transparency with BIOS support.
  • This experiment highlights the end of an era for native DOS compatibility on future laptops.
