(2) About the messages displayed
(a) The GOT will display the following messages if you attempt to install
ROM_BIOS that is not compatible with the GOT to be used.
Should the following messages appear due to wrong operation you
performed, there will be no problems since installation is not executed and
ROM_BIOS is not rewritten.
If the above messages have appeared, hold the above screen in that status
and install the standard monitor OS, communication driver and so on.
POINT
The following message will also appear when you power on your GOT for the first
time.
In this case, the message does not relate to the installation of ROM_BIOS.
