Preconfiguration Information

PCnet-ISA adapters only:

o IRQ Level:	3, 5, 9, 10, 11, 15
o I/O Address:	0x300, 0x320, 0x340, 0x360

The Solaris pcn driver does not support IRQ 4.
On some systems, particularly those with PCI controllers, IRQ 9 may not be usable by a PCnet-ISA adapter; configure the adapter to use another interrupt. PCnet-PCI adapters aren't affected.
