x86: Serial Consoles of Some Sun Fire Systems Do Not Work (6208412)

The serial console (ttya) on the following Sun Fire systems does not work by default:

• Sun Fire V20z

• Sun Fire V40z

• Sun Fire V60x

• Sun Fire V65x

To use the serial console, you must manually configure the system's BIOS.

Workaround: This workaround requires your system to have a Sun keyboard and a display monitor. Follow these steps:

1. Boot the machine.

2. During system boot, press F2 at the prompt to access the Phoenix BIOS.

3. Under Peripherals, change the comm port from disabled to enabled.

4. Save the configuration and boot the system.

5. Use the eeprom command to change input-device and output-device to ttya.

Pressing the Stop and N keys at system boot to reset the low-level firmware to default settings does not work on these systems.
