Re: Can a PCI Slave generate INTA# ?
1. If your device wants to generate an Interrupt, you are responsible for
writing an interrupt program to be installed into machine after system
configuration period and before system normal work. In Windows NT, 98, it
may include a sentence in your system.ini file to install your system driver
(another name in software to handle interrupts) at the right time.
2. If you don't write an interrup program while your device generates an
interrupt, the system has a default interrupt program expecting for any
system-unexpected interrupts that would blue your screen. In DOS, it only
skips the interrupt, but in Windows system, it shows you something that is
