Epson 7500 - Manual (Page 28)

The configuration you define through SETUP is stored in a
special area of memory called CMOS RAM. This memory is
backed up by a battery, so it is not erased when you turn off or
reset the computer. Whenever you reboot the computer, it
checks the settings, and if it discovers a difference between the
information in the CMOS RAM and its actual hardware
configuration, it prompts you to run SETUP. You see a message
such as the following:
FLOPPY DISK TYPE IS SET INCORRECTLY OR
DRIVE ERROR
You also see the following prompt at the bottom of the screen:
Press F1 to continue or Del to start SETUP
If this happens, press to run SETUP and correct the
setting.
Starting the SETUP Program
To start SETUP, make sure there is no diskette in the diskette
drive; then turn on your computer. (If your computer is already
on, turn it off, wait 20 seconds, and then turn it on again.) After
the self test, you see the following prompt at the bottom of the
screen:
Press Del to start SETUP
As soon as you see this message, press
If you do not press within approximately five seconds,
the computer starts loading the operating system and you will
not be able to run SETUP. If this happens, restart the computer
and try again.
When you press you’ll see the first SETUP screen.
