they must not be in consecutive order.
If this driver doesn't work with your equipment, mail me a
description, please.
The driver supports reading of data from the CD and playing of
audio tracks. The audio part should run with WorkMan, xcdplayer,
with the "non-X11" products CDplayer and WorkBone - tell me if
it is not compatible with other software.
MultiSession is supported, "ManySession" (see below) alternatively.
Photo CDs should work, too. At ftp.gwdg.de:/pub/linux/hpcdtoppm
is a package to convert photo CD image files.
I did not have a chance to play with XA or mixed mode CDs yet.
Send one over, if you would like sbpcd to support that.
Photo CDs work, too. At ftp.gwdg.de:/pub/linux/hpcdtoppm/ is a package

The transfer rate will reach 150 kB/sec with standard drives and
the full 300 kB/sec with double-speed drives.
