When 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 (cable not provided) to view the BIOS, a better solution is to use "Remote Access" to the BIOS via the serial port.

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 as soon as you hear the beep, type <TAB> to enter the BIOS Setup, go to the "Advanced" -> "Remote Access Configuration" .  Make the following changes...

  * ''Serial Port Mode -> 19200 8,n,1''
  * ''Redirection After BIOS POST -> Disabled''
  * ''Sredir Memory Display Delay -> Delay 4 Sec''


The results should like the following screen...

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