|  | 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> | 
|  |  |
