both devices are built in the system chassis, to load Win98/Win98SE or Win2000 O/S or application software
into the system, an external device is needed to act as a bridge. There are three major ways to load software
into the system.
1.Use an external FDD:Attach a 3.5 FDD to the external FDD port via the provided external FDD
cable. The 26-pin FDD connector is to be plugged in to the system FDD
connector; the 34-pin standard 3.5 FDD signal connector and the 4-pin FDD
power connector are to connect to the standard 3.5 FDD. Then, configure the
system BIOS setup and insert a 3.5 disk containing necessary software and
start the installation.
2.Use Ethernet: After install the O/S and necessary network utilities, download application
software from the network.
3.Use External CD-ROM/HDD:To use an external CD-ROM or HDD for software installation, an optional P-
IDE device is needed. The P-IDE device is a converter to convert the parallel
port to the IDE interface.
