NCR 53C810 PCI-SCSI I/O Processor Tests
NCR810 Interrupt Test
This test verifies the interrupt connection between the NCR810 and the SIO
controller to the CPU. A general purpose timer is enabled which generates an
interrupt that is dispatched to the CPU through the SIO controller. The console
PALcode dispatches to the NCR810_diag ISR, which clears the interrupt.
Console Command: ncr810_diag -t 7
Miscellaneous Notes
• These tests do not run in parallel with the SCSI exerciser tests.
