Antminer S19 DCENT_OS Firmware: Exact Release Status

beta20261002: Antminer S19 / am2-s19

0.9.0 Experimental; development-key distribution; physical qualification pending. Verify and inspect this exact package only. Do not prepare boot media, flash or update from this row. Signed package and exact-board restrictions take precedence over the broad feed label.

After completed Stop/shutdown, power off, remove SD and restore recorded original boot selection to return to internal firmware. Preserve failed-boot card and diagnostics. Do not assume this trial is qualified recovery media.

Verify this exact artifact, key, source and recovery card

Each exact variant keeps its own route

Verify the complete model and confirmed controller. A sibling image, model family or SD slot does not authorize installation. Read the exact card; inspection-only rows forbid media preparation/install/update. Physical qualification and automatic recovery are not established.

Historical July registry evidence and limitations

Antminer S19 · Released / Experimental

No verified public image for this exact model

Antminer S19 is Released on the Experimental channel. Source identity is public, but no exact verified prebuilt binary, install-matrix lane or recovery path is listed.

Risk: Experimental firmware can brick this miner, cause mining downtime, and may affect warranty coverage. Do not continue until the exact board and recovery path are confirmed.

View release status Inspect the source

Exact board: Zynq/Xilinx source identity; no standalone exact S19 row exists in the canonical install matrix
Verified file: No verified prebuilt
Install: No Exact Model Route
Recovery: No Exact Model Route

The shortest responsible path

Identify: confirm the exact model and physical control-board lane.
Choose: use only the route authorized for that lane; no route means no flashing.
Recover: verify the stop condition and restoration path before any write.

Files and current evidence

No verified prebuilt file is listed for this exact model in registry 2026-09-01.5. Do not substitute another model’s file.

Mining, installation, and recovery boundaries

Mining: The source retains BM1398 identity and shared driver-path work, but this registry does not claim current accepted shares on an exact S19 unit.
Installation: No standalone exact S19 row is published in the canonical install matrix. It must not silently inherit the S19 Pro or S19j Pro route.
Recovery: No exact-model persistent install or stock-restoration route is published.

Proof, gap, and limitations

Proof: BM1398 source identity and driver-path work; no exact-unit accepted-share or installation receipt is asserted.

Open gap: Establish exact control-board identity, accepted shares, package provenance and reversible install/recovery evidence.

S19 does not inherit S19 Pro install evidence.
S19j Pro uses a different ASIC and its package is not compatible.
The nominal source chip count is not represented as live-hardware confirmation.
