A free browser simulator lets technicians change BIOS/UEFI settings, save them, and see how the resulting boot process responds.

Landing page captured for the 2026-09-08 issue.

Field notes

The simulator organizes firmware practice around reference machines rather than a generic settings mockup. Visible examples include an OptiPlex 7020 Tower, EliteBook 840 G10, PRIME B650-PLUS, and ThinkPad T14 Gen 4, with vendor-specific entry keys and menu conventions. Its consequence model includes both ordinary Windows handoff and failure states such as no-POST, 0x7B, and BitLocker recovery. The homepage also exposes a glossary, exam area, documentation links, and a 45-minute course.
