5.2.3 SECONDARY IDE INTERFACE
The secondary IDE interface supports the Multibay device, which may be an optical storage device
(CD-ROM, DVD, LS-120) or a second hard drive mounted in a Multibay adapter that in turn is
installed in the Multibay. Both iPAQ 1.x and 2.0 systems provide a 68-pin female connector
(mounted on a Multibay board) that mates with the corresponding male connector of the Multibay
device or adapter.
