standard CD-ROM technology including superior video and audio playback,
faster data access, and greater storage capacities. The drive uses the latest DVD
technology that reads from specially designed DVD discs as well as standard
audio and video CDs.
Fax/Modem Board
Some systems come with a fax/modem board preinstalled. The board operates as
a fax system and data modem according to the operating system and software
installed. The modem board offers a full-duplex speakerphone and 56,600 bits
per second (bps) data/14,400 bps fax communications.
The fax/modem board is Plug and Play compatible. There are no switches or
jumpers to set if the system is running the Windows 95 or Windows 98
operating system. The fax/modem default settings are COM2, IRQ3. Systems
running the Windows NT 4.0 operating system must be configured for COM2
and IRQ3.
