Epson 7500 - Manual (Page 32)

If you install one type of display adapter card and then change
the adapter (from VGA to CGA or vice-versa), you also may
need to set jumper J5. If you have two types of cards, set the
jumper to match the adapter controlling your primary display.
See Chapter 2 in the User’s Guide for instructions on changing
jumper settings and the manual that came with your monitor
for additional information.
Setting the Self Test Error Level
When you start your system, it performs a self test. The
Halt On option determines the point at which the system will
stop if it finds an error during the self test.
If your computer is running without a keyboard or diskette
drive or it must always start, you can choose one of the options
in the following table to ensure the computer will boot.
