Driver/Interrupt Handler (DIH)
AMP names are defined by $ZZATM. The AMP name is composed of the letter Z
followed by the adapter name and one hexadecimal digit between 1 and F (identifies
the processor number in which the AMP is running). For example, $ZAM11.
Driver/Interrupt Handler (DIH)
The DIH provides an interface to the ATM adapter for clients performing I/O transfers
between a NonStop S-series server and an ATM adapter.
Figure 2-7 on page 2-10 shows the relationship of the DIH and the ATM subsystem.
