Risk: Experimental firmware can brick hardware, cause mining downtime, and may affect warranty coverage. Identify the control board and prove recovery before writing anything.
DCENT_OS 0.9.0: exact-board Experimental status
beta20261002 has 29 exact-board status cards; 29 sets have retained or verified public static URLs. There are 17 raw SD images, 11 route-restricted archives and one BeagleBone developer payload. Only 13 raw-image rows have a lab SD route; 4 are inspection only while permissions conflict. Physical qualification is pending. The automated installer route is unavailable because its signed host does not resolve. Static file availability and installation permission are separate.

What Is DCENT_OS Antminer Firmware?
DCENT_OS is a purpose-built Linux distribution and open-source (GPL-3.0) firmware stack for supported Bitmain Antminer hardware. During the beta, every install should be treated as experimental: wrong images, interrupted writes, unsupported control boards, or NAND flashing on the wrong unit can brick hardware.
The Rust mining daemon and local dashboard expose mining, thermal and diagnostic surfaces. Heat Mode and the local MCP control surface are secondary capabilities whose readiness is build- and board-specific; exact artifact and installation evidence comes first.
The project daemon, dashboard and Buildroot integration are GPL-3.0. Complete firmware images include third-party boot/kernel inputs with unverified source correspondence and redistribution permission. Read the exact release source record. View the source on GitHub.

DCENT_OS Firmware Stack
Three layers, minimal dependencies, and staged control for supported beta images.
DCENT_OS is organized in three layers. A stripped-down Linux system boots the miner. A Rust-powered mining engine talks to supported ASIC hardware and manages hashrate, fans, frequency, and voltage domains where supported. A browser dashboard presents the Space Heater, Mining, and Companion modes from any phone or laptop on your network.
Antminer Hardware Abstraction Layer
The Rust HAL is intended to isolate chip, control-board, PSU, and sensor differences as image-specific support lands.
Every ASIC miner family has different chips, control boards, PSUs, sensors, and board revisions. The Hardware Abstraction Layer is the compatibility boundary between the dashboard and the hardware-specific drivers. During the beta, support is still image-specific: do not assume a model or control board works until its exact SD card image is published.
Secondary capabilities, not readiness claims
The source tree includes autotuning, Heat Mode, MCP/local-agent controls, dashboards and a default-off Stratum V2 implementation. Their presence in source does not prove they are enabled, soaked or independently audited in beta20260709. Treat Stratum V1 as the Antminer baseline unless the exact release record says otherwise.

Before You Flash
- Identify the exact Antminer model and variant.
- Identify the control board family: XIL, BB, CV, or AML.
- Confirm that the exact model and board lane has a named artifact, then review its install-readiness evidence.
- Read release notes, checksum notes, and recovery instructions.
- Do not flash production miners or hardware you cannot recover.

DCENT_OS Firmware FAQ
What hardware does DCENT_OS support?
The July registry remains historical. beta20261002 has 29 exact-board status cards; 29 sets have retained or verified public static URLs. There are 17 raw SD images, 11 route-restricted archives and one BeagleBone developer payload. Only 13 raw-image rows have a lab SD route; 4 are inspection only while permissions conflict. Physical qualification is pending. The automated installer route is unavailable because its signed host does not resolve. Static file availability and installation permission are separate.
Is DCENT_OS really free? No dev fee?
October default configuration disables donations at 0%; retained miner settings may differ. The optional contribution redirects scheduled mining time in Stratum V1, with 0–5% configured. Set it to 0 or disable it to opt out; saved changes require a daemon restart. Accepted shares and payout percentages are not guaranteed. Settings → Donation Fee displays the pool and worker; API/TOML configuration is available.
How does Space Heater Mode work?
Space Heater is a dashboard view, not a verified room thermostat. The current source reports room-temperature control as unavailable and does not establish a working room setpoint. In the S19j Pro Xilinx hybrid lane, power-profile requests of 600, 900 and 1200 W are saved requests, not proof that hardware applied them. BTU/h is calculated from power and inherits its measurement or estimation limits; it is not a measured room-heating result. Exact-controller compatibility and physical validation remain required.
What is Stratum V2 and why does it matter?
Stratum V2 is the next-generation mining protocol for encrypted miner-pool communication and job negotiation. DCENT_OS implements a native V2 stack, but it is default-off behind a readiness gate while live submit/accept and failover soak remain pending. The July Antminer artifacts should be treated as V1 unless exact release notes state otherwise.
What is the Grid Curtailment API?
It is a planned API track for external systems such as smart home hubs, utility demand-response programs, and fleet controllers to request throttling or pause states. Beta behavior will be documented per image.
How does the Home Assistant integration work?
DCENT_OS ships a CGMiner-compatible API on port 4028 in beta, which pyasic and Home Assistant tooling already speak. Deeper native integration — local sensors, power states, and automations for heat, mining, and curtailment workflows — follows as the API stabilizes for supported images.
Will flashing DCENT_OS void my warranty?
Flashing third-party firmware on most ASIC miners can void the manufacturer warranty. During the beta it can also brick a control board, fail to boot, interrupt revenue, or require SD card, UART, or serial recovery. Do not flash production miners or hardware you cannot afford to troubleshoot.
Can DCENT_OS brick my miner?
Yes. Beta firmware can brick a control board, corrupt configuration, void warranty, or leave a miner offline until manual recovery works. A wrong XIL / BB / CV / AML image is especially dangerous. Only install if you understand the recovery process and have a tested rollback path ready (SD reflash or UART).
How does DCENT_OS compare to Braiins OS+ or VNish?
No performance superiority is established for the current Experimental files. Compare accepted shares, wall power and noise on the same exact model, controller, cooling and firmware versions. DCENT_OS has no mandatory fee; October donations default to disabled at 0%, while retained settings may differ.
Can DCENT_OS overclock my Antminer?
The autotuner runs a closed-loop per-chip frequency/voltage search with measured feedback, PVT clamps, ramp limits, and rollback, and advanced controls expose per-chip frequency targets and per-domain voltage where the hardware and beta image support them. Overclocking can damage hardware, cause instability, and brick a miner during beta. Do not use it on production equipment.
Does DCENT_OS work with my mining pool?
The target is pool-agnostic Bitcoin mining. Stratum V1 is the current baseline. The native Stratum V2 implementation is default-off and readiness-gated; confirm the exact protocol support in the release notes for the artifact you are testing.
Which public artifacts are available now?
29 exact-board static file sets are available for beta20261002: 17 raw SD images, 11 route-restricted archives and one BeagleBone payload. Use the exact card for original names, signatures and installation limits. Physical qualification is pending; the automated installer route is unavailable.
Beta Means Real Risk.
Choose the exact model and confirmed board, download the complete matching set, and run its read-only verification. Keep existing firmware if no authorized route matches.
