          * AC Adapter (brick): AC Power Adapter 60W, 12V, 5A
          * Fan: (included on NF9HQL-525 board heat sink)
      * __With PCIe Expansion Card Support__
          * Jetway Case JC-11x-B Series((only a **PCI**-riser-card is included with the JC-11x-B case, no **PCIe**-riser!)) (or similar)
          * AC Adapter (brick) is included, Internal ATX Power Supply not used

Only if a Compact Flash card is used, and it supports DMA, much higher disk performance can be obtained by enabling LIBATA DMA for Compact Flash.  Enable from the CLI by issuing the following command:

  set-kcmd libata.dma=5

**BIOS Setup via Serial Port:**

While it is possibly to use a VGA cable to connect to the board's internal VGA header((in some countries (e.g. Germany) you may need to order the VGA header cable separately)) to view the BIOS((press "DEL" at startup)), a better solution is to use "Remote Access" to the BIOS via the serial port.  Since version A02 of the NF9H BIOS the console redirect feature is enabled((the VGA header cable is **needed** for the BIOS upgrade)).

First, configure your serial terminal program to support ANSI color and 115200 baud.  If you are using minicom be sure to add the ' ''-c on'' ' option to the minicom command line, otherwise the ANSI colors will not be distinguishable in the BIOS Setup screen.

!!Note ->!! Leave ''Serial Port Mode -> 115200 8,n,1'' for AstLinux 1.3.0 and later.

Second, on startup type F4 (<ESC>OS) to enter the BIOS Setup, go to the "Integrated Peripherals" -> "Remote Access Configuration" .  Make the following changes...

  * ''Serial Port Mode -> 19200 8,n,1''
  * ''Redirection After BIOS POST -> Disabled''

The results should like the following screen...

Your system has at least one included CPU fan, you may want to enable Fan Smart Mode in the BIOS.  This will automatically vary the fan speed according to it's corresponding temperature sensor.  In the BIOS Setup, go to the "PC Health Status" -> "Smart FAN Configurations"

{{:userdoc:jetway_nf9hql-525-fan-bios2.png?nolink|Fan BIOS}}

In this example, the fan runs at 35% of full speed at 45 C and below, then linearly ramps up to 100% full speed at 75 C and above.
The above example slows the CPU fan for normal operation and reduces the noise.

Finally, save the above BIOS changes, reboot, and reconfigure you serial terminal program if you changed the baud rate.
