The controller fails to respond and various IRQ LEDs in the 1–4 range flash once per
second.
This LED pattern indicates an internal microprocessor error
occurred in the controller. Shut down the computer and unplug all
cables. Restart the computer. If the condition does not reappear,
reconnect the cables and devices, one device at a time, until the
faulty hard drive or cable is isolated. If the error persists, contact
Adaptec Technical Support.

During the installation of SCO UNIX with the Adaptec controller as the boot controller,
the following message appears:
Warning: Controller cannot install interrupts vecno=xx, type=2, IPL=5
Vector xx is private.
SCO UNIX reserves certain interrupts for its internal use. This error
indicates that the Adaptec controller has been assigned one of these
reserved interrupts. Assign a different interrupt to the controller and
start the installation again.
You want the system to boot from a drive that is not attached to an Adaptec controller.
However, during startup, the controller BIOS message appears first, indicating that a
drive attached to an Adaptec controller will be the boot drive.
Use SMOR to disable Boot Enable for that controller. This prevents
the Adaptec controller from being used as the boot controller for the
system.
