This allows runtime-configurable `behavior' of the cdrom-drive, - independent of the driver. - -Features since version 0.33 ---------------------------- -- Full audio support, that is, both workman, workbone and cdp work - now reasonably. Reading TOC still takes some time. xmcd has been - reported to run successfully. -- Made auto-probe code a little better, I hope - -Features since version 0.28 ---------------------------- -- Full speed transfer rate (300 kB/s). -- Minimum kernel memory usage for buffering (less than 3 kB). -- Multisession support. -- Tray locking. -- Statistics of driver accessible to the user. -- Module support. -- Auto-probing of adapter card's base port and irq line, - also configurable at boot time or module load time. - - -Decide how you are going to use the driver. There are two -options: - - (a) installing the driver as a resident part of the kernel - (b) compiling the driver as a loadable module - - Further, you must decide if you are going to specify the base port - address and the interrupt request line of the adapter card cm260 as - boot options for (a), module parameters for (b), use automatic - probing of these values, or hard-wire your adaptor card's settings - into the source code. If you don't care, you can choose - autoprobing, which is the default. In that case you can move on to - the next step. - -Compiling the kernel --------------------- -1) move to /usr/src/linux and do a - - make config - - If you have chosen option (a), answer yes to CONFIG_CM206 and - CONFIG_ISO9660_FS. - - If you have chosen option (b), answer yes to CONFIG_MODVERSIONS - and no (!) to CONFIG_CM206 and CONFIG_ISO9660_FS. - -2) then do a - - make clean; make zImage; make modules - -3) do the usual things to install a new image (backup the old one, run - `rdev -R zImage 1', copy the new image in place, run lilo). Might - be `make zlilo'. - -Using the driver as a module ----------------------------- -If you will only occasionally use the cd-rom driver, you can choose -option (b), install as a loadable module. You may have to re-compile -the module when you upgrade the kernel to a new version. - -Since version 0.96, much of the functionality has been transferred to -a generic cdrom interface in the file cdrom.c. The module cm206.o -depends on cdrom.o. If the latter is not compiled into the kernel, -you must explicitly load it before cm206.o: - - insmod /usr/src/linux/modules/cdrom.o - -To install the module, you use the command, as root - - insmod /usr/src/linux/modules/cm206.o - -You can specify the base address on the command line as well as the irq -line to be used, e.g. - - insmod /usr/src/linux/modules/cm206.o cm206=0x300,11 - -The order of base port and irq line doesn't matter; if you specify only -one, the other will have the value of the compiled-in default. You -may also have to install the file-system module `iso9660.o', if you -didn't compile that into the kernel. - - -Using the driver as part of the kernel --------------------------------------- -If you have chosen option (a), you can specify the base-port -address and irq on the lilo boot command line, e.g.: - - LILO: linux cm206=0x340,11 - -This assumes that your linux kernel image keyword is `linux'. -If you specify either IRQ (3--11) or base port (0x300--0x370), -auto probing is turned off for both settings, thus setting the -other value to the compiled-in default. - -Note that you can also put these parameters in the lilo configuration file: - -# linux config -image = /vmlinuz - root = /dev/hda1 - label = Linux - append = "cm206=0x340,11" - read-only - - -If module parameters and LILO config options don't work -------------------------------------------------------- -If autoprobing does not work, you can hard-wire the default values -of the base port address (CM206_BASE) and interrupt request line -(CM206_IRQ) into the file /usr/src/linux/drivers/cdrom/cm206.h. Change -the defines of CM206_IRQ and CM206_BASE. - - -Mounting the cdrom ------------------- -1) Make sure that the right device is installed in /dev. - - mknod /dev/cm206cd b 32 0 - -2) Make sure there is a mount point, e.g., /cdrom - - mkdir /cdrom - -3) mount using a command like this (run as root): - - mount -rt iso9660 /dev/cm206cd /cdrom - -4) For user-mounts, add a line in /etc/fstab - - /dev/cm206cd /cdrom iso9660 ro,noauto,user - - This will allow users to give the commands - - mount /cdrom - umount /cdrom - -If things don't work --------------------- - -- Try to do a `dmesg' to find out if the driver said anything about - what is going wrong during the initialization. - -- Try to do a `dd if=/dev/cm206cd | od -tc | less' to read from the - CD. - -- Look in the /proc directory to see if `cm206' shows up under one of - `interrupts', `ioports', `devices' or `modules' (if applicable). - - -DISCLAIMER ----------- -I cannot guarantee that this driver works, or that the hardware will -not be harmed, although I consider it most unlikely. - -I hope that you'll find this driver in some way useful. - - David van Leeuwen - david@tm.tno.nl - -Note for Linux CDROM vendors ------------------------------ -You are encouraged to include this driver on your Linux CDROM. If -you do, you might consider sending me a free copy of that cd-rom. -You can contact me through my e-mail address, david@tm.tno.nl. -If this driver is compiled into a kernel to boot off a cdrom, -you should actually send me a free copy of that cd-rom. - -Copyright ---------- -The copyright of the cm206 driver for Linux is - - (c) 1995 David A. van Leeuwen - -The driver is released under the conditions of the GNU general public -license, which can be found in the file COPYING in the root of this -source tree. |
