[comp.os.msdos.programmer] HGC and vertical retrace

ose21@sci.kun.nl (John Graat) (12/06/90)

Hello everybody,

Does anyone know if it is possible to let the HGC generate an interrupt
when a vertical retrace occurs?
I know it can be can done with an EGA-card, but with a HGC too?

Thanks in advance.
