Wistron Spears schematic for an Intel UMA configuration, revision R1.0, packed in a RAR archive of 1.19 MB. UMA means the board relies on integrated graphics with no discrete GPU, so the video and VRAM sections of a dedicated-graphics variant will not apply. Use it to trace power rails, check the CPU core regulator, follow the boot sequence and locate components on a suspect line. Unpack with 7-Zip or WinRAR, and verify that the Spears code and revision printed on your motherboard match before relying on the values.
