IBM 704 - Manual (Page 162)

Installing Adapters
systems that support the Plug and Play feature become available,
your server will automatically configure itself when you install
EISA, ISA, and PCI Plug and Play devices.
Your server comes with a video controller. This video controller is
an integrated component on the system board. It is not in an
expansion slot. The integrated video controller has super video
graphics array (SVGA) technology.
The integrated video controller is not removable. If you want to
disable this controller and use a video adapter instead, you must
install a PCI video adapter in an expansion slot. When you install a
PCI video adapter, the server BIOS automatically disables the
integrated video controller.
The following illustration shows the PCI and EISA expansion slots
in your server.
