6.8 AlphaStation 255: PCI Configuration Restriction
V7.1
The OpenVMS Alpha operating system does not support PCI option cards
configured in PCI slot 0 on any AlphaStation 255 series systems.
PCI slot 0 is the lowest physical PCI option slot on AlphaStation 255 series
systems. The interrupt signal for this slot is shared with the built-in Ethernet
port. Because the OpenVMS Alpha operating system does not currently permit
PCI devices to share an interrupt line, a PCI device installed in slot 0 will not
function correctly or may cause errors to occur with the built-in Ethernet port. As
a result of this restriction, AlphaStation 255 series systems support a maximum
of two PCI option cards, configured in slot 1 and slot 2.
