1 | NOTE: This driver is obsolete. Digi provides a 2.6 driver (dgdm) at |
| 2 | http://www.digi.com for PCI cards. They no longer maintain this driver, | |
| 3 | and have no 2.6 driver for ISA cards. | |
| 4 | ||
| 0418726b | 5 | This driver requires a number of user-space tools. They can be acquired from |
| 1da177e4 LT |
6 | http://www.digi.com, but only works with 2.4 kernels. |

| 9 | The Digi Intl. epca driver. | |
| 10 | ---------------------------- | |
| 11 | The Digi Intl. epca driver for Linux supports the following boards: | |
| 12 | ||
| 13 | Digi PC/Xem, PC/Xr, PC/Xe, PC/Xi, PC/Xeve | |
| 14 | Digi EISA/Xem, PCI/Xem, PCI/Xr | |
| 15 | ||
| 16 | Limitations: | |
| 17 | ------------ | |
| 18 | Currently the driver only autoprobes for supported PCI boards. | |
| 19 | ||
| 20 | The Linux MAKEDEV command does not support generating the Digiboard | |
| 21 | Devices. Users executing digiConfig to setup EISA and PC series cards | |
| 22 | will have their device nodes automatically constructed (cud?? for ~CLOCAL, | |
| 23 | and ttyD?? for CLOCAL). Users wishing to boot their board from the LILO | |
| 24 | prompt, or those users booting PCI cards may use buildDIGI to construct | |
| 25 | the necessary nodes. | |
| 26 | ||
| 27 | Notes: | |
| 28 | ------ | |
| 29 | This driver may be configured via LILO. For users who have already configured | |
| 30 | their driver using digiConfig, configuring from LILO will override previous | |
| 31 | settings. Multiple boards may be configured by issuing multiple LILO command | |
| 32 | lines. For examples see the bottom of this document. | |
| 33 | ||
| 34 | Device names start at 0 and continue up. Beware of this as previous Digi | |
| 35 | drivers started device names with 1. | |
| 36 | ||
| 37 | PCI boards are auto-detected and configured by the driver. PCI boards will | |
| 38 | be allocated device numbers (internally) beginning with the lowest PCI slot | |
| 39 | first. In other words a PCI card in slot 3 will always have higher device | |
| 40 | nodes than a PCI card in slot 1. | |
| 41 | ||
| 42 | LILO config examples: | |
| 43 | --------------------- | |
| 44 | Using LILO's APPEND command, a string of comma separated identifiers or | |
| 45 | integers can be used to configure supported boards. The six values in order | |
| 46 | are: | |
| 47 | ||
| 48 | Enable/Disable this card or Override, | |
| 49 | Type of card: PC/Xe (AccelePort) (0), PC/Xeve (1), PC/Xem or PC/Xr (2), | |
| 50 | EISA/Xem (3), PC/64Xe (4), PC/Xi (5), | |
| 51 | Enable/Disable alternate pin arrangement, | |
| 52 | Number of ports on this card, | |
| 53 | I/O Port where card is configured (in HEX if using string identifiers), | |
| 54 | Base of memory window (in HEX if using string identifiers), | |
| 55 | ||
| 56 | NOTE : PCI boards are auto-detected and configured. Do not attempt to | |
| 57 | configure PCI boards with the LILO append command. If you wish to override | |
| 58 | previous configuration data (As set by digiConfig), but you do not wish to | |
| 59 | configure any specific card (Example if there are PCI cards in the system) | |
| 60 | the following override command will accomplish this: | |
| 61 | -> append="digi=2" | |
| 62 | ||
| 63 | Samples: | |
| 64 | append="digiepca=E,PC/Xe,D,16,200,D0000" | |
| 65 | or | |
| 66 | append="digi=1,0,0,16,512,851968" | |
| 67 | ||
| 68 | Supporting Tools: | |
| 69 | ----------------- | |
| 70 | Supporting tools include digiDload, digiConfig, buildPCI, and ditty. See | |
| 71 | drivers/char/README.epca for more details. Note, | |
| 72 | this driver REQUIRES that digiDload be executed prior to it being used. | |
| 73 | Failure to do this will result in an ENODEV error. | |
