9This is the README for the sjcd cdrom driver, version 1.6.
10
11This file is meant as a tips & tricks edge for the usage of the SANYO CDR-H94A
12cdrom drive. It will grow as the questions arise. ;-)
13For info on configuring the ISP16 sound card look at Documentation/cdrom/isp16.
14
15The driver should work with any of the Panasonic, Sony or Mitsumi style
16CDROM interfaces.
17The cdrom interface on Media Magic's soft configurable sound card ISP16,
18which used to be included in the driver, is now supported in a separate module.
19This initialisation module will probably also work with other interfaces
20based on an OPTi 82C928 or 82C929 chip (like MAD16 and Mozart): see the
21documentation Documentation/cdrom/isp16.
22
23The device major for sjcd is 18, and minor is 0. Create a block special
24file in your /dev directory (e.g., /dev/sjcd) with these numbers.
25(For those who don't know, being root and doing the following should do
26the trick:
27 mknod -m 644 /dev/sjcd b 18 0
28and mount the cdrom by /dev/sjcd).
29
30The default configuration parameters are:
31 base address 0x340
32 no irq
33 no dma
34(Actually the CDR-H94A doesn't know how to use irq and dma.)
35As of version 1.2, setting base address at boot time is supported
36through the use of command line options: type at the "boot:" prompt:
37 linux sjcd=<base_address>
38(where you would use the kernel labeled "linux" in lilo's configuration
39file /etc/lilo.conf). You could also use 'append="sjcd=<configuration_info>"'
40in the appropriate section of /etc/lilo.conf
41If you're building a kernel yourself you can set your default base
42i/o address with SJCD_BASE_ADDR in /usr/src/linux/drivers/cdrom/sjcd.h.
43
44The sjcd driver supports being loaded as a module. The following
45command will set the base i/o address on the fly (assuming you
46have installed the module in an appropriate place).
47 insmod sjcd.o sjcd_base=<base_address>
