CD-ROM Module Parameters

NotePlease Note
 

Not all of the cards that are listed are supported. Please check the hardware compatibility list on Red Hat's World Wide Web site at http://www.redhat.com/support/docs/hardware.html to make sure your card is supported.

One of the more commonly used parameters, the hdX=cdrom parameter, can be entered at the boot prompt, as it deals with support for IDE/ATAPI CD-ROMs, which is part of the kernel.

In the tables below, most modules without any parameters listed are either able to auto-probe to find the hardware, or require you to manually change settings in the module source code, and recompile.

NotePlease Note
 

Most newer Sound Blaster cards come with IDE interfaces. For these cards, you do not need to use sbpcd parameters, only use hdx parameters.
