CD-ROM Module Parameters

	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 your CD-ROM drive 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) can be entered at the boot prompt (boot:) during installation. This exception to the rule is allowed since it deals with support for IDE/ATAPI CD-ROMs, which is 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 they require you to manually change settings in the module source code and recompile.

Table A-1. Hardware Parameters

Hardware	Module	Parameters
ATAPI/IDE CD-ROM Drives		hd`X`=cdrom
Aztech CD268-01A, Orchid CD-3110, Okano/Wearnes CDD110, Conrad TXC, CyCDROM CR520, CyCDROM CR540 (non-IDE)	`aztcd.o`	aztcd=`io_port`
Sony CDU-31A CD-ROM	`cdu31a.o`	cdu31a=`io_port`,`IRQ` OR cdu31a_port=`base_addr` cdu31a_irq=`irq`
Philips/LMS CDROM drive 206 with cm260 host adapter card	`cm206.o`	cm206=`io_port,IRQ`
Goldstar R420 CD-ROM	`gscd.o`	gscd=`io_port`
ISP16, MAD16, or Mozart sound card CD-ROM interface (OPTi 82C928 and OPTi 82C929) with Sanyo/Panasonic, Sony, or Mitsumi drives	`isp16.o`	isp16=`io_port`,`IRQ`,`dma`, `drive_type` OR isp16_cdrom_base=`io_port` isp16_cdrom_irq=`IRQ` isp16_cdrom_dma=`dma` isp16_cdrom_type=`drive_type`
Mitsumi CD-ROM, Standard	`mcd.o`	mcd=`io_port`,`IRQ`
Mitsumi CD-ROM, Experimental	`mcdx.o`	mcdx=`io_port_1`,`IRQ_1`, `io_port_n`,`IRQ_n`
Optics storage 8000 AT "Dolphin" drive, Lasermate CR328A	`optcd.o`
Parallel-Port IDE CD-ROM	`pcd.o`
SB Pro 16 Compatible	`sbpcd.o`	sbpcd=`io_port`
Sanyo CDR-H94A	`sjcd.o`	sjcd=`io_port` OR sjcd_base=`io_port`
Sony CDU-535 & 531 (some Procomm drives)	`sonycd535.o`	sonycd535=`io_port`

Here are some examples of these modules in use:

Table A-2. Hardware Parameters Configuration Examples

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
Mitsumi drive on a MAD16 soundcard at IO Addr 330 and IRQ 1, probing DMA	isp16=0x330,11,0,Mitsumi
Sony CDU 531 at IO address 320	sonycd535=0x320

	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.
