Technical Information 1-21
The Yamaha OPL3-SA3 includes a full Plug and Play interface. Each logical device is
configured into the host environment using the Plug and Play configuration methodologies.
The audio subsystem requires two DMA channels and one interrupt.
DISKETTE DRIVE SUPPORT
A diskette drive is not included in the system. However, the riser card contains a diskette
drive connector and controller. A diskette drive with its own power source can be
connected by a ribbon cable to the diskette drive connector on the riser card. You must
enable the diskette drive controller in BIOS Setup to use a diskette drive in the NetPC
system (see “Setup Utility” in Section 2).
HARD DISK DRIVE
All systems ship with one internal 3 1/2-inch hard disk drive (1-inch high, thin-height)
installed in the internal drive slot in the top half of the chassis. Drives are available in
2.0-GB and 3.2-GB Western Digital models.
A two-connector hard disk drive IDE cable connects to the hard disk and the primary
connector on the riser card. The riser card has one IDE/PCI interface connector (primary
only) for connecting IDE storage devices such as hard disk drives. Logically, the connector
supports up to two IDE devices. Physically, there is room for one hard disk in the chassis.
An optional second hard disk drive can be added to the primary channel if the cable is
replaced with a three-connector IDE cable. If an additional hard disk drive is added to the
primary IDE channel, configure both devices as non-Ultra DMA.
Use the “Storage Device Installation” procedures in Section 3 when replacing the hard disk.
Connector locations are given in Appendix A. Jumper settings are given in Appendix B.
Hard disk drive specifications are given in Table 1-17 and Table 1-18.
POWER SUPPLY
The power supply is mounted inside the top chassis. It supplies power to the system board,
option board, hard disk, keyboard, and mouse. A fan inside the chassis provides system
ventilation. The power supply provides 51 watts (rated). Connector locations are given in
Appendix A.
The power supply connector differs from the standard NLX and ATX power supply
connectors. Pin 18 of the PowerMate NetPC power supply is used for thermal fan speed
control and not for -5V.
WARNING:
Do not use a standard NLX or
ATX power supply to operate the NetPC system,
as this will cause the fan circuit to fail.
