5.2.4 Installing ROM_BIOS
Point
(1) Data installed in the GOT
When the ROM_BIOS is installed, the monitor data, special data and OS in the
GOT are deleted.
If the data must be retained, upload them in advance.
(2) During installation of ROM_BIOS
Once the ROM_BIOS installation is started, it cannot be interrupted.
Do not turn OFF the power of the GOT/PC or unplug the communication cable
to interrupt. Otherwise, the GOT may became inoperable.
<GOT recovery method>
If the GOT goes down due to the operation above, install the system program
again by the following procedure:
Remove the communication module/board or optional module mounted
on the GOT (remove the communication cable for the communication
interface built-in GOT) before installation.
Turn OFF the GOT.
Turn ON the GOT while pressing two locations shown below on the GOT
at the same time.
Message "Reinstall the ROM_BIOS/OS" appears on the GOT.
Complete installation according to the GOT instruction.
If the GOT is not recovered by the above method, contact your local
Mitsubishi service center or representative.
