+/* Board configuration array.
+ * This array defines the hardware irq and address for up to IP2_MAX_BOARDS
+ * (4 supported per ip2_types.h) ISA board addresses and irqs MUST be specified,
+ * PCI and EISA boards are probed for and automagicly configed
+ * iff the addresses are set to 1 and 2 respectivily.
+ *    0x0100 - 0x03f0 == ISA
+ *	         1        == PCI
+ *	         2        == EISA
+ *	         0        == (skip this board)
+ * This array defines the hardware addresses for them. Special 
+ * addresses are EISA and PCI which go sniffing for boards. 
+
+ * In a multiboard system the position in the array determines which port
+ * devices are assigned to each board: 
+ *		board 0 is assigned ttyF0.. to ttyF63, 
+ *		board 1 is assigned ttyF64  to ttyF127,
+ *		board 2 is assigned ttyF128 to ttyF191,
+ *		board 3 is assigned ttyF192 to ttyF255. 
+ *
+ * In PCI and EISA bus systems each range is mapped to card in 
+ * monotonically increasing slot number order, ISA position is as specified
+ * here.
+
+ * If the irqs are ALL set to 0,0,0,0 all boards operate in 
+ * polled mode. For interrupt operation ISA boards require that the IRQ be 
+ * specified, while PCI and EISA boards any nonzero entry 
+ * will enable interrupts using the BIOS configured irq for the board. 
+ * An invalid irq entry will default to polled mode for that card and print
+ * console warning.
+ 
+ * When the driver is loaded as a module these setting can be overridden on the 
+ * modprobe command line or on an option line in /etc/conf.modules 
+ * or /etc/modules.conf depending on your distrubution.
+ * If the driver is built-in the configuration must be 
+ * set here for ISA cards and address set to 1 and 2 for PCI and EISA.
+ *
+ * Here is an example that shows most if not all possibe combinations:
+
+ *static ip2config_t ip2config =
+ *{
+ *	{11,1,0,0},		// irqs
+ *	{				// Addresses
+ *		0x0308,		// Board 0, ttyF0   - ttyF63// ISA card at io=0x308, irq=11
+ *		0x0001,		// Board 1, ttyF64  - ttyF127//PCI card configured by BIOS
+ *		0x0000,		// Board 2, ttyF128 - ttyF191// Slot skipped
+ *		0x0002		// Board 3, ttyF192 - ttyF255//EISA card configured by BIOS
+ *												 // but polled not irq driven
+ *	}
+ *};
+ */
+
+ /* this structure is zeroed out because the suggested method is to configure
+  * the driver as a module, set up the parameters with an options line in
+  * /etc/modules.conf or /etc/conf.modules and load with modprobe, kerneld or
+  * kmod, the kernel module loader
+  */
+static ip2config_t ip2config =
+{
+	{0,0,0,0},		// irqs
+	{				// Addresses
+		0x0000,		// Board 0, ttyF0   - ttyF63
