BIOS Configuration
Home menu level: /system routerboard bios
Description
In addition to BIOS own setup possibilities, it is possible to configure BIOS parameters in
RouterOS condole
Property Description
baud-rate (1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600 | 115200; default: 9600) - initian
bitrate of the onboard serial port
beep-on-boot (yes | no; default: yes) - whether to beep during boot procedure (to indicate that it has
succeeded)
boot-delay (time: 0s..10s; default: 1s) - how much time to wait for a key storke while booting
boot-device (etherboot-ide | etherboot-only | ide-only | try-etherboot-once) - specifies from which
device the RouterBoard will boot
• etherboot-ide - boot from etherboot, if it fails, boot from ide
• etherboot-only - boot only from etherboot
• ide-only - boot only from ide
• try-etherboot-once - boot from etherboot once, then returns to previous settings
cpu-mode (power-save | regular; default: power-save) - whether to enter CPU suspend mode in
HTL instruction. Most OSs use HLT instruction during CPU idle cycle. When CPU is in suspend
mode, it consumes less power, but in low-temperatire conditions it is recommended to choose
regular mode, so that overall system temperature would be greater
debug-level (none | low | high) - BIOS output debug level
• none - no debugging output
• low - show only some debugging information
• high - show all debugging information about the boot process
enter-setup-on (any-key | delete-key; default: any-key) - which key will cause the BIOS to enter
configuration mode during boot delay. Note that in some serial terminal programs, it is impossible
to use Delete key to enter the setup - in this case it might be possible to do this with the Backspace
key
etherboot-timeot (time; default: 1m) - how much time to wait for booting from ethernet
memory-settings (fail-safe | optimal; default: auto) - SDRAM memory speed
