How to Test a FreeDOS Monthly Test Release Without Risking Your Main Installation
Verify media, clone a VM or disk image, compare package changes, capture regressions, and report reproducible results.
Download the current Tyymm test image from the official site and verify the published checksum. Clone a VM or make a full image of real media; never test an unreleased kernel on the only copy of a working system.
Read changes.log, select representative boot, memory, storage, networking, application, and Windows-compatibility tests, then change no unrelated configuration. Capture exact hardware/VM settings and logs. Confirm a suspected regression against the stable release and a clean configuration.
Report the smallest reproducible case with test-release name, package versions, expected/actual behavior, and recovery steps. Testing is useful only when another contributor can repeat it.
