Installing a Sony CRX195A1 CDRW Drive in Red Hat 7.3
Let's suppose you had a different combination of drives. In a system with two hard drives (/dev/hda and /dev/hdb) and a CD-ROM on /dev/hdc you would add the CD writer to /dev/hdd. Further, let's suppose that you didn't need or want to do disk-to-disk copies. After physically connecting the drive and powering up, you would first add the line append="hdd=ide-scsi" to lilo.conf and then add the line ignore="hdd" to /etc/modules.conf. Reboot once more and voilà--a working CD writer.
It should be noted that you can enable IDE-SCSI emulation on any combination of drives you wish. They needn't be contiguous in the drive chain, nor do you need to enable IDE-SCSI for all the drives on an IDE channel--you may do so selectively. That is, you can enable IDE-SCSI emulation for /dev/hdd but not /dev/hdc, as in the example above. Also, you only have to enable IDE-SCSI on optical drives other than your CD writer if you wish xcdroadst/cdrecord to see them and be able to do disk-to-disk copies.

System as Tested
Pentium III 1000MHz
Red Hat Linux 7.3 with default 2.4.18-3 kernel
cdrecord version 1.10-11 (provided by Red Hat)
xcdroast version .98-a9-8 (provided by Red Hat)
The drive was cheap ($89.99), and the $20 mail-in rebate really was what made me decide on this model. I tested writing at speeds up to 32x (the version of xcdroast that I have only goes up to 32x), and I was impressed with the overall writing speed of the drive. In the ISO burning test, I burned the Gentoo live CD ISO image (approximately 230MB) in 66 seconds! The Sony name made me feel comfortable, as I have had various other Sony optical drives in the past with uniformly good results. cdrecord did use the burnproof capabilities of the drive, which was another plus.
The bad part is no Linux support. The complete lack of help from live support was disappointing, and the drive came with no extras or frills. For instance, there were no blank disks of any sort included in the box. The manuals and quick-start guides were disappointing and next to useless even for a Windows installation. I would not recommend this drive for an inexperienced Windows user, but for a Linux user who had read all the HOWTOs and FAQs, it should be no problem at all.
The FAQs and HOWTOs I read were distribution-neutral, and the steps contained therein should work equally well for any modern distro.

Add append="hdX=ide-scsi" to lilo.conf or grub.conf, where X is the letter of the CD writer. Remember to add in any additional optical drives if you wish to do CD-to-CD copying, for example, append="hdb=ide-scsi hdc=ide-scsi".
Modify /etc/modules.conf to include the line options ide-cd ignore="hdX", where X is the letter(s) of the drive(s) you are using.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
