| |
The Sanyo 3 CD changer that is commonly found only on Gateway 2000 computers (G2k was the primary OEM vendor) is now supported through a kernel patch to operate as a *changer* under Linux. The drive would function using only the CD in the first slot of the changer under Linux but would not function as an actual changer.
Support for the standard ATAPI command to change CDs has already been added to the 2.0 kernel ide-cd driver. However, the Sanyo 3 CD changer was under developement before this relatively new ATAPI command was established. As a result the standard ATAPI changer support does not work with the Sanyo 3 CD changer. But through the help of Jeff Lightfoot who is stationed in Japan, I now have been provided the information required from Sanyo on how to support the changer functionality of the Sanyo 3 CD changer. A patch to enhance the ide-cd driver has already been created and is available at: http://orion.it.luc.edu/~bgallia/cdrom.html
If you or any Linux user you know owns the Sanyo 3 CD changer then please make them aware of this patch! They will have to upgrade to the Linux 2.0 kernel if they have not already done so to use it. But once the patch is put into place, the kernel will support the Sanyo 3 CD changer just the same as it supports any other IDE/ATAPI multiplatter CDROM drive. Users will have to check the linux/Documentation/cdrom/ide-cd file for more information including the cdload.c source code required to request a switch of CDs.
Since this is a relatively trival patch (makes some small changes to only 3 functions in only the ide-cd.c file), I hope to submit this patch to Linus to be included in either the 2.0.2 or 2.1.0 kernel (as he sees fit). Scott Snyder, the maintainer of the IDE CDROM driver, has already looked at the patch and seems to approve it's use for being included in the Linux kernel.
If anyone has any success/horror stories with using the patch then feel free to email me at: bgallia@luc.edu
