DCENT_OS documentation: start here

DCENT_OS decision guide

Start with your miner, not a generic flashing guide

Choose the exact model and board first. The S9 has a guarded removable-media trial; the S19j Pro archive is limited to DCENT_OS self-update. Other lanes need their own evidence.

Risk: Experimental firmware can brick hardware, cause mining downtime, and may affect warranty coverage. Confirm the exact board and recovery path before any write.

DCENT_OS hardware evidence and install readiness

Six axes stay separate: availability, maturity, binary, mining, installation and recovery. Evidence on one axis never silently promotes another.

DCENT_OS status and evidence by exact Antminer model and control-board lane
HardwareRelease statusVerified prebuiltMining evidenceInstall / recoveryDetails
Antminer S9
Zynq/Xilinx am1-s9; redundant-slot NAND, with a separate removable-media boot route		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		A verified S9 Zynq/Xilinx sysupgrade archive and a bootable SD image are listed in the current artifact ledger.The project platform matrix reports standalone cold-boot mining with pool-accepted shares on the BM1387 Zynq lane; this website does not claim an independent reproduction.Bitmain's S9 recovery documentation distinguishes complete-board CRT0401/CRT0402 (JP4), CRT0302 (AB pads), and CRT0301 (no SD slot). The public DCENT_OS trial documents only the JP4 route; no other PCB revision inherits that authorization. The current public evidence still lacks a complete witnessed first-install, soak and persistent-recovery capstone for this release.
For the documented removable-media trial, power off, return JP4 to its photographed original position, remove the SD card, then boot untouched NAND. Other S9 PCB revisions require their own verified route. A witnessed persistent stock-restoration procedure for this exact release is not published.		Evidence page
Antminer S9 SE
Ctrl_C43 / XC7Z007S, tracked separately as am1-s9se		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S9 SE prebuilt binary is listed in the current artifact ledger. The model still has AVAILABILITY: RELEASED and MATURITY: EXPERIMENTAL; build-output metadata is not a download.The public source records exact model identity and detection evidence, but no callable production mining runtime or accepted-share proof for this lane.The am1-s9se install row marks update, external media and general installation not implemented or denied. Do not use the S9 image.
No model-specific installation write is authorized and no model-specific recovery-write route is published.		Evidence page
Antminer T17
Zynq/Xilinx am2-t17 with a PIC16 control path		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified T17 prebuilt binary is listed in the current artifact ledger.The source row is management-only and does not establish a current accepted-share mining path on a live T17.The am2-t17 install row has no implemented update or external-media route and denies installation.
No model-specific persistent write or recovery procedure is authorized.		Evidence page
Antminer S17
Zynq/Xilinx; source mapping uses am2-s17p and must not be read as an S17 Pro install promise		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S17 prebuilt binary is listed in the current artifact ledger.The current evidence records a BM1397 source profile, not a reproduced accepted-share result on an exact S17 fleet unit.The mapped source target has update and external media not implemented and installation denied. No separate exact-model route is published.
No exact S17 persistent installation or stock-restoration procedure is authorized.		Evidence page
Antminer T17+
Zynq/Xilinx am2-t17plus with a PIC16 control path		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified T17+ prebuilt binary is listed in the current artifact ledger.The source identifies the BM1397/PIC16 route, but the public evidence does not establish accepted shares on an exact T17+ unit.The am2-t17plus install row marks update, media and recovery not implemented and installation denied.
No model-specific persistent write or recovery route is published.		Evidence page
Antminer S17+
Zynq/Xilinx am2-s17plus with a PIC16 control path		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S17+ prebuilt binary is listed in the current artifact ledger.The source identifies the BM1397/PIC16 route, but the public evidence does not establish accepted shares on an exact S17+ unit.The am2-s17plus install row marks update, media and recovery not implemented and installation denied.
No model-specific persistent write or recovery route is published.		Evidence page
Antminer S19
Zynq/Xilinx source identity; no standalone exact S19 row exists in the canonical install matrix		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S19 prebuilt binary is listed in the current artifact ledger.The source retains BM1398 identity and shared driver-path work, but this registry does not claim current accepted shares on an exact S19 unit.No standalone exact S19 row is published in the canonical install matrix. It must not silently inherit the S19 Pro or S19j Pro route.
No exact-model persistent install or stock-restoration route is published.		Evidence page
Antminer S19 Pro
Zynq/Xilinx am2-s19pro with redundant slots		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S19 Pro prebuilt binary is listed in the current artifact ledger. A build producer name is not a public release asset.Historical cold-boot work produced nonce flow, but no pool-accepted share is proven for the current native BM1398 path; current electrical admission remains fail-closed.The am2-s19pro update mechanism is experimental and lab-only. Public-beta installation is false and no general stock-firmware first-install route is published.
Generated boot-media evidence is lab-only; no model-specific operator recovery procedure is published.		Evidence page
Antminer S19j Pro
Verified artifact: am2-s19j Zynq/Xilinx; BeagleBone, Amlogic, CVitek and STM32MP15 are separate, unauthorized lanes for that file		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		A verified S19j Pro Zynq/Xilinx sysupgrade archive is listed in the current artifact ledger.The project matrix reports accepted shares on the Zynq lane and historical runtime proof on BeagleBone; this website does not claim an independent reproduction.The verified package supports a guarded DCENT_OS-to-DCENT_OS update on am2-s19j. Public vendor-stock first installation remains an evidence gap, and public_beta_install is false in the source matrix.
No witnessed vendor-stock first-install and stock-restoration capstone is published for the exact artifact.		Evidence page
Antminer S19k Pro
Amlogic am3-s19k, single-slot, NoPic lane		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S19k Pro prebuilt binary is listed in the current artifact ledger. Build-producer metadata is not a download URL.The current project ledger records a bounded Track-1 temporary-runtime accepted-share proof with terminal SafeOff, not an endurance or installed-image qualification.The am3-s19k host-rootfs-window update is experimental and lab-only. No external-media route or public first-install procedure is authorized.
Recovery is evidence-only in the source matrix; no general operator recovery runbook is published.		Evidence page
Antminer S21
Amlogic am3-s21, single-slot, NoPic lane		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S21 prebuilt binary is listed in the current artifact ledger.The project matrix records accepted shares on an earlier runtime path; that result has not been reproduced on a verified current public binary.The am3-s21 host-rootfs-window path is experimental and lab-only. Stock AMLCtrl in-place installation remains blocked.
No external-media or model-specific stock-restoration route is published.		Evidence page
Antminer S21 XP
Amlogic am3-s21xp; package and exact topology evidence only		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S21 XP prebuilt binary is listed in the current artifact ledger.The source records exact topology and package-format evidence, but the installed runtime remains management-only and no accepted-share proof is claimed.The am3-s21xp install row has no implemented update mechanism, denies installation and authorizes no persistent update.
No external-media, installation-write or recovery route is published.		Evidence page
Antminer S21 Pro
Amlogic am3-s21pro, single-slot, NoPic lane		AVAILABILITY: RELEASED
MATURITY: EXPERIMENTAL		No verified S21 Pro prebuilt binary is listed in the current artifact ledger.The source records an exact BM1370/Amlogic profile, but no current accepted-share proof on a verified public binary is claimed.The am3-s21pro host-rootfs-window update is experimental and lab-only, with no authorized external-media route.
No model-specific operator stock-restoration route is published.		Evidence page
