12.1.5 VGA INTERRUPT
The video controller can generate an interrupt request (INTR) signal to indicate that the
controller has reached the end of an active field (VSYNC pulse to the CRT monitor).
The interrupt can be connected to and available on the PCI bus INTB line for any PCI
devices connected on the bus, or the interrupt can generate an ISA interrupt request.
§
Settings
To enable the VGA interrupt, install the jumper W12.
To connect the interrupt request to the PCI INTB line, install the jumper W9.
