A.2. CD-ROM Module Parameters

Note Note
 

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.

Table A-1. Hardware Parameters

Here are some examples of these modules in use:

Configuration Example
ATAPI CD-ROM, jumpered as master on the second IDE channel hdc=cdrom
non-IDE Mitsumi CD-ROM on port 340, IRQ 11 mcd=0x340,11
Three non-IDE Mitsumi CD-ROM drives using the experimental driver, io ports 300, 304, and 320 with IRQs 5, 10 and 11 mcdx=0x300,5,0x304,10,0x320,11
Sony CDU 31 or 33 at port 340, no IRQ cdu31=0x340,0 OR cdu31_port=0x340 cdu31a_irq=0
Aztech CD-ROM at port 220 aztcd=0x220
Panasonic-type CD-ROM on a SoundBlaster interface at port 230 sbpcd=0x230,1
Phillips/LMS cm206 and cm260 at IO 340 and IRQ 11 cm206=0x340,11
Goldstar R420 at IO 300 gscd=0x300

Note Note
 

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).
