ian@0 1 NOTE: This driver is obsolete. Digi provides a 2.6 driver (dgdm) at
ian@0 2 http://www.digi.com for PCI cards. They no longer maintain this driver,
ian@0 3 and have no 2.6 driver for ISA cards.
ian@0 4
ian@0 5 This driver requires a number of user-space tools. They can be acquired from
ian@0 6 http://www.digi.com, but only works with 2.4 kernels.

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