| NOTE: This driver is obsolete. Digi provides a 2.6 driver (dgdm) at |
| http://www.digi.com for PCI cards. They no longer maintain this driver, |
| and have no 2.6 driver for ISA cards. |
| |
| This driver requires a number of user-space tools. They can be acquired from |
| http://www.digi.com, but only works with 2.4 kernels. |
| |
| |
| The Digi Intl. epca driver. |
| ---------------------------- |
| The Digi Intl. epca driver for Linux supports the following boards: |
| |
| Digi PC/Xem, PC/Xr, PC/Xe, PC/Xi, PC/Xeve |
| Digi EISA/Xem, PCI/Xem, PCI/Xr |
| |
| Limitations: |
| ------------ |
| Currently the driver only autoprobes for supported PCI boards. |
| |
| The Linux MAKEDEV command does not support generating the Digiboard |
| Devices. Users executing digiConfig to setup EISA and PC series cards |
| will have their device nodes automatically constructed (cud?? for ~CLOCAL, |
| and ttyD?? for CLOCAL). Users wishing to boot their board from the LILO |
| prompt, or those users booting PCI cards may use buildDIGI to construct |
| the necessary nodes. |
| |
| Notes: |
| ------ |
| This driver may be configured via LILO. For users who have already configured |
| their driver using digiConfig, configuring from LILO will override previous |
| settings. Multiple boards may be configured by issuing multiple LILO command |
| lines. For examples see the bottom of this document. |
| |
| Device names start at 0 and continue up. Beware of this as previous Digi |
| drivers started device names with 1. |
| |
| PCI boards are auto-detected and configured by the driver. PCI boards will |
| be allocated device numbers (internally) beginning with the lowest PCI slot |
| first. In other words a PCI card in slot 3 will always have higher device |
| nodes than a PCI card in slot 1. |
| |
| LILO config examples: |
| --------------------- |
| Using LILO's APPEND command, a string of comma separated identifiers or |
| integers can be used to configure supported boards. The six values in order |
| are: |
| |
| Enable/Disable this card or Override, |
| Type of card: PC/Xe (AccelePort) (0), PC/Xeve (1), PC/Xem or PC/Xr (2), |
| EISA/Xem (3), PC/64Xe (4), PC/Xi (5), |
| Enable/Disable alternate pin arrangement, |
| Number of ports on this card, |
| I/O Port where card is configured (in HEX if using string identifiers), |
| Base of memory window (in HEX if using string identifiers), |
| |
| NOTE : PCI boards are auto-detected and configured. Do not attempt to |
| configure PCI boards with the LILO append command. If you wish to override |
| previous configuration data (As set by digiConfig), but you do not wish to |
| configure any specific card (Example if there are PCI cards in the system) |
| the following override command will accomplish this: |
| -> append="digi=2" |
| |
| Samples: |
| append="digiepca=E,PC/Xe,D,16,200,D0000" |
| or |
| append="digi=1,0,0,16,512,851968" |
| |
| Supporting Tools: |
| ----------------- |
| Supporting tools include digiDload, digiConfig, buildPCI, and ditty. See |
| drivers/char/README.epca for more details. Note, |
| this driver REQUIRES that digiDload be executed prior to it being used. |
| Failure to do this will result in an ENODEV error. |
