Boot Errors
After power-on, all user LEDs (LEDs 1 to 4) are switched on for a short time (to determine that all LEDs
are working). If there are errors happened during the BIOS initialization, an error code is displayed with
user LEDs (note that if LED5 is on, then there is a serious hardware damage, and RouterBOARD may not
be used anymore):
LED2 is on – no RAM detected
LED1 and LED2 are on – testing of the 1

megabyte of RAM failed
BIOS Configuration
BIOS parameters may be configured through the onboard RS232C asynchronous serial interface. To
connect to it, use a standard null-modem cable (pin-out is given in the Appendix). By default, the port is
set to 9600bit/s, 8 data bits, 1 stop bit, no parity, hardware (RTS/CTS) flow control.
To enter the BIOS configuration screen, press any key (or only [Delete] key (or [Backspace] key – see
the note for the respective configurable option), depending on the actual configuration) just after the
BIOS is asking for it:
