A.2. CD-ROM Module Parameters

NoteNote
 

Not all of the CD-ROM drives that are listed are supported. Please check the Hardware Compatibility List on Red Hat's website at http://hardware.redhat.com to make sure the device is supported.

Even though parameters are specified after loading the driver disk and specifying the device, one of the more commonly used parameters hdX=cdrom (where X corresponds to the appropriate drive letter) can be entered at a boot prompt during installation. This is allowed since it effects IDE/ATAPI CD-ROMs, which are already part of the kernel.

In the following tables, most modules listed without any parameters can either be auto-probed to find the hardware or will require manual changes to settings in the module source code and a recompile.

NoteNote
 

Most newer Sound Blaster cards come with IDE interfaces. For these cards, do not use sbpcd parameters; only use hdX parameters (where X corresponds to the appropriate drive letter).
