Setup
Your Raptor MicroATX features General Software Embedded BIOS
2000. The system configuration parameters are set via the BIOS setup.
Since the BIOS Setup resides in the ROM BIOS, it is available each
time the computer is turned on.
General Software’s EMBEDDED BIOS brand BIOS (Basic
Input/Output System) pre-boot firmware is the industry’s standard
product used by most designers of embedded X86 computer equipment
in the world today. Its superior combination of configurability and
functionality enables it to satisfy the most demanding ROM BIOS
needs for embedded designers. Its modular architecture and high degree
of configurability make it the most flexible BIOS in the world.
When your platform is powered on, Embedded BIOS tests and
initializes the hardware and programs the chipset and other peripheral
components. During this time, Power On Self Test (POST) progress
codes are written by the system BIOS to I/O port 80h, allowing the user
to monitor the progress with a special monitor. Appendix B lists the
POST codes and their meanings.
During early POST, no video is available to display error messages
should a critical error be encountered; therefore, POST uses beeps on
the speaker to indicate the failure of a critical system component during
this time. Consult Appendix B for a list of Beep codes used by the
BIOS.
Starting BIOS Setup
When a keyboard and video device are attached, the MicroATX can
display either a traditional character-based PC BIOS display with
memory count-up, or it can display a graphical POST with splash
screen and progress icons. Both POST displays accept a <DEL> key
press to enter the setup screen, and both display boot-time progress
activity displays. The graphical display shows the status of file system
devices, but omits character-based PCI resource display. The text-based
POST displays the memory count-up and the PCI resource assignment
table.
