Setting Up a Target System on the x86 Platform

On x86 platforms, use the eeprom command to make serial port A the console. This procedure is the same as the SPARC platform procedure. See Setting Up a Target System on the SPARC Platform. The eeprom command causes the console to switch to serial port A (COM1) during reboot.

Note –

x86 machines do not transfer console control to the tip connection until an early stage in the boot process unless the BIOS supports console redirection to a serial port. In SPARC machines, the tip connection maintains console control throughout the boot process.
