|The Linux CD-ROM HOWTO
I have already mentioned the documentation files, typically installed in /usr/src/linux/Documentation/cdrom. These can be a gold mine of useful information.
Enhanced IDE/Fast-ATA/ATA-2 FAQ
The following Usenet news groups cover CD-ROM related topics:
A FAQ document on IDE and ATA devices can be found at ftp://rtfm.mit.edu/pub/usenet/news.answers/pc-hardware-faq/enhanced-IDE/ and at http://www.seagate.com/techsuppt/faq/faqlist.html.
The Linux Software Map (LSM) is an invaluable reference for locating Linux software. The LSM home page is at http://www.ExecPC.com/lsm/. and there is an on-line browsable version at http://www.boutell.com/lsm/.
Another great site for finding Linux applications is http://www.freshmeat.net/.
The Linux mailing list has a number of "channels" dedicated to different topics. To find out how to join, send a mail message with the word "help" as the message body to email@example.com.
The Linux Documentation Project has produced several books on Linux, including Linux Installation and Getting Started. These are freely available by anonymous FTP from major Linux archive sites or can be purchased in hardcopy format.
Finally, a shameless plug: If you want to learn a lot more about multimedia under Linux (especially CD-ROM and sound card applications and programming), check out my book Linux Multimedia Guide, ISBN 1-56592-219-0, published by O'Reilly and Associates. As well as the original English version, French and Japanese translations are now in print. For details, call 800-998-9938 in North America or check the web page http://www.ora.com/catalog/multilinux/noframes.html.
