|  | /* 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/modprobe.conf. | 
|  | * 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/modprobe.conf and load with modprobe or kmod, the kernel | 
|  | * module loader | 
|  | */ | 
|  |  | 
|  | /* This structure is NOW always initialized when the driver is initialized. | 
|  | * Compiled in defaults MUST be added to the io and irq arrays in | 
|  | * ip2.c.  Those values are configurable from insmod parameters in the |
