Drives supported by these -drivers came packed with Media Magic's multi media kit, which also -included the ISP16 card. The idea (thanks Leo Spiekman) -to move it from these drivers into a separate module and moreover, not to -rely on the MAD16 sound driver, are as follows: --duplication of code in the kernel is a waste of resources and should - be avoided; --however, kernels and notably those included with Linux distributions - (cf Slackware 3.0 included version 0.5 of the isp16 configuration - code included in the drivers) don't always come with sound support - included. Especially when they already include a bunch of cdrom drivers. - Hence, the cdrom interface should be configurable _independently_ of - sound support. - -The ISP16, MAD16 and Mozart sound cards have an OPTi 82C928 or an -OPTi 82C929 chip. The interface on these cards should work with -any cdrom attached to the card, which is 'electrically' compatible -with Sanyo/Panasonic, Sony or Mitsumi non-ide drives. However, the -command sets for any proprietary drives may differ -(and hence may not be supported in the kernel) from these four types. -For a fact I know the interface works and the way of configuration -as described in this documentation works in combination with the -sjcd (in Sanyo/Panasonic compatibility mode) cdrom drivers -(probably with the optcd (in Sony compatibility mode) as well). -If you have such an OPTi based sound card and you want to use the -cdrom interface with a cdrom drive supported by any of the other cdrom -drivers, it will probably work. Please let me know any experience you -might have). -I understand that cards based on the OPTi 82C929 chips may be configured -(hardware jumpers that is) as an IDE interface. Initialisation of such a -card in this mode is not supported (yet?). - -The suggestion to configure the ISP16 etc. sound card by booting DOS and -do a warm reboot to boot Linux somehow doesn't work, at least not -on my machine (IPC P90), with the OPTi 82C928 based card. - -Booting the kernel through the boot manager LILO allows the use -of some command line options on the 'LILO boot:' prompt. At boot time -press Alt or Shift while the LILO prompt is written on the screen and enter -any kernel options. Alternatively these options may be used in -the appropriate section in /etc/lilo.conf. Adding 'append="<cmd_line_options>"' -will do the trick as well. -The syntax of 'cmd_line_options' is - - isp16=[<port>[,<irq>[,<dma>]]][[,]<drive_type>] - -If there is no ISP16 or compatibles detected, there's probably no harm done. -These options indicate the values that your cdrom drive has been (or will be) -configured to use. -Valid values for the base i/o address are: - port=0x340,0x320,0x330,0x360 -for the interrupt request number - irq=0,3,5,7,9,10,11 -for the direct memory access line - dma=0,3,5,6,7 -and for the type of drive - drive_type=noisp16,Sanyo,Panasonic,Sony,Mitsumi. -Note that these options are case sensitive. -The values 0 for irq and dma indicate that they are not used, and -the drive will be used in 'polling' mode. The values 5 and 7 for irq -should be avoided in order to avoid any conflicts with optional -sound card configuration. -The syntax of the command line does not allow the specification of -irq when there's nothing specified for the base address and no -specification of dma when there is no specification of irq. -The value 'noisp16' for drive_type, which may be used as the first -non-integer option value (e.g. 'isp16=noisp16'), makes sure that probing -for and subsequent configuration of an ISP16-compatible card is skipped -all together. This can be useful to overcome possible conflicts which -may arise while the kernel is probing your hardware. -The default values are - port=0x340 - irq=0 - dma=0 - drive_type=Sanyo -reflecting my own configuration. The defaults can be changed in -the file linux/drivers/cdrom/ips16.h. - -The cdrom interface can be configured at run time by loading the -initialisation driver as a module. In that case, the interface -parameters can be set by giving appropriate values on the command -line. Configuring the driver can then be done by the following -command (assuming you have iso16.o installed in a proper place): - - insmod isp16.o isp16_cdrom_base=<port> isp16_cdrom_irq=<irq> \ - isp16_cdrom_dma=<dma> isp16_cdrom_type=<drive_type> - -where port, irq, dma and drive_type can have any of the values mentioned -above. - - -Have fun! |
