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 aquired 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. + +Documentation: +-------------- +Complete documentation for this product may be found in the tool package. + +Sources of information and support: +----------------------------------- +Digi Intl. support site for this product: + +-> http://www.digi.com + +Acknowledgments: +---------------- +Much of this work (And even text) was derived from a similar document +supporting the original public domain DigiBoard driver Copyright (C) +1994,1995 Troy De Jongh.
