PDF schematic for the BIOSTAR TB250 BTC motherboard with the board code IB25C-AHS at revision 6.0, compressed into a 1.01 MB RAR. The circuit diagram covers power sequencing, VRM, PCIe slot wiring and the support chips, which helps when chasing missing rails or dead slots on mining rigs. Any PDF reader opens it after extraction. Pair it with a BIOS image for the same revision when fixing firmware faults, and check that the revision silkscreen on the PCB reads 6.0 so component values line up.
