Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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