Set TB350-BTC / TA320-BTC for mining

Please update BIOS.
(How to update BIOS by key "F12" :　https://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=491) 
TB350-BTC => B35BG209.BSS 
TA320-BTC => A32BGB30.BSS
(TA320-BTC default setting already as same as below)

After update (For TB350-BTC), you have to manual set and check as below : 
1. Enable : Above 4G Decoding (BIOS / Advanced / PCI Subsystem settings / Above 4G Decoding  )
2. Enable : Mining Mode (BIOS / Chipset / Mining mode)
3. Disable : CSM Support (BIOS / Advanced / CSM Configuration / CSM Support) 

Set on-board primary display.(Only for Bristol and Raven CPU)

BIOS / Chipset / North Bridge / GFX Configuration / 
Primary Video Device => IGD Video
Surround View => Auto

Set PCIe Speed

• Hardware 
  Ensure hardware connect properly first.
  (1). Check VGA card 
  Try to only plug one VGA card in PEX16_1 (long yellow slot) directly without riser card => Check whether display
  
  (2). Check Riser card 
  Try to plug VGA card with only one riser card to test per PEX1 and PEX16_1 => Check whether display.
  
  (3). Check CPU socket Pin
  Remove CPU and check CPU Socket pin whether bent.(If bent , might be no power on or no display.
  
  (4). Check Riser Card and VGA card power are connected properly.
  
  (5). Refer Mining Guide to deploy Rig : https://www.biostar.com.tw/app/en/event/crypto_mining/page4_2.htm
  
   
• Under BIOS
  (1). Ensure BIOS up to latest.
  TB250-BTC => B25CFB29.BSS or latest
  TB250-BTC+ => B25EFB29.BSS or latest
  TB250-BTC Pro  => B25DB29.BSS or latest
  After update and get POST , BIOS will detect PCIE and show each slot status automatically.
  
  (2). Plug all VGA card in slot and into BIOS to check whether get (Present)
  PEX1_1-PEX1_11 => Chipset Menu /PCH-IO Configuration / PCI Express Configuration.
  PEX16_1 => Chipset Menu / System Agent(SA) Configuration
  
  (3). Check BIOS setting. (Or use BIOS default setting)
  Enable Mining mode (Chipset / Mining Mode)
  Enable Above 4G Decoding (Chipset / System Agent (SA) Configuration / Above 4G MMIO BIOS Assignment)
  Disable CSM Support (Boot / CSM support )
  =>Disable CSM support option , it will only recognize UEFI device.
   
• Under Windows
  ***Please make sure BIOS get all VGA card first.***
  (1). Check OS be installed by UEFI format (How to check install by UEFI)
  
  (2). Check Device Manager do not show yellow exclamation mark.
  
  (3). Check VGA card driver up to date.

1. Under Windows10 , press key "Windows" + "R" 
2. Key in msinfo32
   
3. System Information will show BIOS mode.
   

• Under Windows : 
  Each brand of VGA card support up to 8.(VGA card driver limitation)
  So,you could deploy AMD*8+Nvidia*4 or AMD*4+Nvidia*8 or AMD*6+Nvidia*6 ...etc
  
  ***UPDATE***According AMD relaese VGA card driver ReLive Edition 17.11.1  , It can support up to 12 VGA card.(as picture)

• Under EthOS :
  Only support one brand VGA card to use at same time.
  Example : 9 Gigabyte AORUS GeForce GTX 1060 6G have to use EthOS.
  If AMD card , Enable CSM support option.(Path : BIOS/Boot Menu/CSM Support => Enable)

• Note: We couldn't guarantee that overclock VGA card will be work stable and smoothly.

(1) Install two PCI-E M.2 SSD on motherboard.

(2) Boot into BIOS/Advanced/SATA and RST configuration

(3) Set SATA mode selection to Intel RST Premium, both PCIe storage to RST controlled

(4) Set Boot/storge to UEFI, then Save & Exit BIOS

Please update ethOS to the latest version (1.2.3 or above) and enable CSM support in BIOS for multiple AMD GPU mining.

note: update BIOS to the latest version according to your motherboard model. mining mode is set to enabled as default. Nvidia GPU does not need to enable CSM support.

For mining purpose in  BIOS version (7/10) and later version of BIOS, default setting for CSM is set to disabled. In which video is set to UEFI mode. If your GPU does not support UEFI then display through GPU is not supported. Please disconnect all GPU and connect monitor to on-board DVI port, then set on-board display as primary display device in BIOS. Then you can connect GPU back to motherboard and display through on-board DVI at the same time.

1. Power off and unplug all VGA card.
2. Connect moniter display with onboard DVI.
3. Power on and press "DEL" into BIOS set primary display from onboard.(BIOS/Chipset/System Agest(SA) Configuration/Primary display => IGFX).
   Then press "F10" save & exit.
4. Power off again and plug back all VGA card and power on to check whether get all VGA cards.
   PEX1_1-PEX1_5 => Chipset Menu / PCI Express Configuration.
   PEX16_1 => Chipset Menu / System Agent(SA) Configuration
5. If not get all , please check riser card whether work properly.  

If  AMD VGA card overclock and after install driver still show Yellow exclamation mark in Device Manager , here has a method might be fixed issue.

1.  Enter into Windows OS, and install graphic cards driver.
2. After installed driver finished,restart system and check :
   My Computer > Device Manager > To check the graphic cards if all can be recognized OK. 
   ==> If graphics cards show Yellow exclamation mark, it needs install Patch file
3. Run Patch file as Administrator then install.  After install done,please restart system and enter into Windows OS, and check all graphic cards can be recognized well with No Yellow exclamation mark . 
   
4. If check no problem,customer can start to mining.
