Setting Up the Test System for x86 Platforms

On x86 platforms, use the eeprom command to make serial port A the console. The procedure for this is the same as for SPARC platform and is discussed above. Executing the eeprom commands causes the console to switch to serial port A (COM1) during reboot.

Note -

Unlike SPARC machines, where the tip connection maintains console control throughout the boot process, x86 machines don't transfer console control to the tip connection until an early stage in the boot process.
