When repairing the Antminer S19 BHB42801 hash board, we need to use the test fixture with the BITMAIN official S19 test file to diagnose the specific fault of the hash board. Download, copy and paste in TF/SD card, and then install it in the test fixture.
Become a student of ZMRC bitcoin mining training course, you can download this file for free and get our technical support.
