1 | NOTE: This driver is obsolete.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 | |||
5 | This driver requires a number of user-space tools. They can be aquired from | ||
6 | http://www.digi.com, but only works with 2.4 kernels. | ||
7 | |||
8 | |||
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. | ||
