- *                       which send an interrupt when ready for a command.
- * 2.02  Dec 11, 1994 -- Cache the TOC in the driver.
- *                       Don't use SCMD_PLAYAUDIO_TI; it's not included
- *                       in the current version of ATAPI.
- *                       Try to use LBA instead of track or MSF addressing

- *                       Properly supply the page number field in the
- *                        MODE_SELECT command.

- *
- *       For those wishing to work on this driver, please be sure you download
- *       and comply with the latest ATAPI standard.  This document can be
- *       obtained by anonymous ftp from fission.dt.wdc.com in directory:
