-This is the README file for the Optics Storage 8000 AT CDROM device driver.
-
-This is the driver for the so-called 'DOLPHIN' drive, with the 34-pin
-Sony-compatible interface. For the IDE-compatible Optics Storage 8001
-drive, you will want the ATAPI CDROM driver. The driver also seems to
-work with the Lasermate CR328A. If you have a drive that works with
-this driver, and that doesn't report itself as DOLPHIN, please drop me
-a mail.
-
-The support for multisession CDs is in ALPHA stage. If you use it,
-please mail me your experiences. Multisession support can be disabled
-at compile time.
-
-You can find some older versions of the driver at
- dutette.et.tudelft.nl:/pub/linux/
-and at Eberhard's mirror
- ftp.gwdg.de:/pub/linux/cdrom/drivers/optics/
-
-Before you can use the driver, you have to create the device file once:
- # mknod /dev/optcd0 b 17 0
-
-To specify the base address if the driver is "compiled-in" to your kernel,
-you can use the kernel command line item (LILO option)
- optcd=0x340
-with the right address.
-
-If you have compiled optcd as a module, you can load it with
- # insmod /usr/src/linux/modules/optcd.o
-or
- # insmod /usr/src/linux/modules/optcd.o optcd=0x340
-with the matching address value of your interface card.
-
-The driver employs a number of buffers to do read-ahead and block size
-conversion. The number of buffers is configurable in optcd.h, and has
-influence on the driver performance. For my machine (a P75), 6 buffers
-seems optimal, as can be seen from this table:
-
-#bufs kb/s %cpu
-1 97 0.1
-2 191 0.3
-3 188 0.2
-4 246 0.3
-5 189 19
-6 280 0.4
-7 281 7.0
-8 246 2.8
-16 281 3.4
-
-If you get a throughput significantly below 300 kb/s, try tweaking
-N_BUFS, and don't forget to mail me your results!
-
-I'd appreciate success/failure reports. If you find a bug, try
-recompiling the driver with some strategically chosen debug options
-(these can be found in optcd.h) and include the messages generated in
-your bug report. Good luck.
