Optional SSD:

If a SSD is installed, it is internally connected via a SATA3 controller. It is recommended to use a SATA3 SSD, as some older SATA2 SSD's may not reliably boot, quite possibly only an issue in isolated cases with older SATA2 SSD's with old firmware.

BIOS Setup via 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.

Second, on startup after you hear the beep and some text, type <TAB> to enter the BIOS Setup, go to the “Advanced” → “Serial Port Console Redirection” . Make the following changes…

  • Bits per second → 19200
  • Redirection After BIOS POST → Bootloader

The results should like the following screen…

Console Redirection BIOS

Finally, save the above BIOS changes, reboot, and reconfigure you serial terminal program to 19200 baud, this will match what AstLinux expects.
