| 13.Cd "device rp0 at isa? port 0x180" | 13.Pp 14For ISA cards, you must specify the port address in 15.Pa /boot/device.hints : 16.Cd hints.rp.0.at="isa" 17.Cd hints.rp.0.port="0x100" |
| 14.Sh DESCRIPTION 15This driver provides a kernel device driver for the 16.Tn RocketPort 17and 18.Tn RocketPort RA 19serial boards. 20These boards provide 8, 16, or 32 high-speed serial ports 21while requiring only 68 bytes of I/O space for all 8, 16, --- 41 unchanged lines hidden (view full) --- 63above address ranges. 64The I/O address range used by any of the 65.Tn RocketPort 66cards must not conflict with any other cards in the system, 67including other 68.Tn RocketPort 69cards. 70The starting range of the I/O ports used by each card | 18.Sh DESCRIPTION 19This driver provides a kernel device driver for the 20.Tn RocketPort 21and 22.Tn RocketPort RA 23serial boards. 24These boards provide 8, 16, or 32 high-speed serial ports 25while requiring only 68 bytes of I/O space for all 8, 16, --- 41 unchanged lines hidden (view full) --- 67above address ranges. 68The I/O address range used by any of the 69.Tn RocketPort 70cards must not conflict with any other cards in the system, 71including other 72.Tn RocketPort 73cards. 74The starting range of the I/O ports used by each card |
| 71must match with the I/O address specified in the kernel 72configuration file. | 75must match with the I/O address specified in 76.Pa /boot/device.hints . |
| 73.Pp 74Since the first 75.Tn RocketPort 76uses 68 I/O addresses, if the first card is 77set to use an I/O block starting at 0x100, 78it will occupy the I/O ports between 0x100 and 0x143. 79This means that the second, third, or fourth 80.Tn RocketPort 81board may not use the block of addresses starting at 0x140, 82since the first three I/O addresses of that range 83are used by the first board. 84This is an important point to keep in mind. 85.Pp | 77.Pp 78Since the first 79.Tn RocketPort 80uses 68 I/O addresses, if the first card is 81set to use an I/O block starting at 0x100, 82it will occupy the I/O ports between 0x100 and 0x143. 83This means that the second, third, or fourth 84.Tn RocketPort 85board may not use the block of addresses starting at 0x140, 86since the first three I/O addresses of that range 87are used by the first board. 88This is an important point to keep in mind. 89.Pp |
| 90If you have two ISA cards, one installed at 0x100 and the 91second installed at 0x180, then you should add the following to 92.Pa /boot/device.hints : 93.Pp 94.Dl hints.rp.0.at="isa" 95.Dl hints.rp.0.port="0x100" 96.Dl hints.rp.1.at="isa" 97.Dl hints.rp.1.port="0x180" 98.Pp |
