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> 48 49 50Have fun! 51 52If something is wrong, please email to vadim@rbrf.ru 53 or vadim@ipsun.ras.ru 54 or model@cecmow.enet.dec.com 55 or H.T.M.v.d.Maarel@marin.nl 56 57It happens sometimes that Vadim is not reachable by mail.
