NOTE: This driver is obsolete.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.
