Routine Description:
|
|
|
|
This is the interrupt service routine for the Ultra124 SCSI adapter.

It reads the interrupt register to determine if the adapter is indeed

the source of the interrupt and clears the interrupt at the device.
|
|
If the adapter is interrupting because a mailbox is full, the MSCP is
|
|
retrieved to complete the request.
