| /* 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 |
| * case of modules or from command line parameters (ip2=io,irq) when |
| * compiled in. |

| { |
| {0,0,0,0}, // irqs |
| { // Addresses |
