04.13. Does support ATAPI (IDE) CD-ROMs?
The current versions of most operating systems support ATAPI CD-ROMs.
That includes OS/2 3.0, Linux 1.2 and above, and Win95.
Unfortunately, hardware manufacturers have started designing these CD-
ROM units while the ATAPI standard was still evolving, so there are
now a couple of versions implemented in the real world. Moreover, the
complexity and novelty of ATAPI means that there are some variations
even among implementations of the same revision. Writing an OS ATAPI
driver that works with all CD-ROMs, therefore, is a daunting task and
not all have succeeded equally well. So although these OSs all support
ATAPI, they do not work with all ATAPI equipment.
See Microsoft KnowledgeBase Q131499, "CD-ROM Drives Requiring Real-
Mode Drivers", for more details on Win95 support. For OS/2, take a
look at <http://www.austin.ibm.com/pspinfo/os2hw.html>; for updated
drivers use the latest install disk upgrade or
