Hi everyone,
I have got V3-471G SYSTEM BLOCK DIAGRAM(Broad code is ZQSA). According this diagram, I have filled C345--C348 with 4 0.01uF/16v Capacitances and welded a mSATA connector on CN7.
[attachment=16041][attachment=16040]
After Inserted a Kingston half size SSD, BIOS and Windows can't detect this disk. I have tested +3V_SATA, wire to PCH(SATA port 1) are OK."SATA1GP / GPIO19" is pulled up used as Boot BIOS Selection 0 [bit-0] for SPI.
It seems BIOS have blocked SATA Port 1,because SATA Controller's PCI config space shows offset 0xE00FA092==0x21(Bus0,Dev31,Func2 ONLY Port 0 and 5 Enabled).

Can anybody help me unlock this port?THX!
