Troubleshooting
Question: I see some of my PCI devices sharing IRQs, but the sys-
tem seems to be fine. Is this correct or not?
Answer: Some PCI Bus Mastering devices can share IRQs without perfor-
mance penalties. These devices are designed to work correctly while shar-
ing IRQs. See Table 3-1 below for details on shared IRQs.
Question: I successfully installed the audio driver for my onboard
audio, but can barely hear the sound from my speakers. What's
the problem?
Answer: (1) This may be due to a software setting. In Windows, go to
<Start>, <Settings>, <Control Panel>, <Multimedia> and finally <CD Music>.
Check the box beside the line that reads "Enable digital CD audio for this
CD-ROM drive". (2) If the previous step does not work, your speaker may
require an amplifier to function. If you are playing music from an external
audio CDROM, you must connect an audio cable (not included) from your CD
unit to either the CD or CD_1 header on the motherboard. See page 2-9 for
details.
Question: I installed my microphone correctly but I can't record any sound.
What should I do?
Answer: Go to <Start>, <Programs>, <Accessories>, <Entertainment> and then
<Volume Control>. Under the Properties tab, scroll down the list of devices in
the menu and check the box beside "Microphone".
Question: How do I connect the ATA66 cable to my IDE device(s)?
Answer: The 80-wire/40-pin ATA66 IDE cable that came with your system
(370SWD/370SWT only) has two connectors to support two drives. This
special cable must be used to take advantage of the speed the ATA66
technology offers. Connect the blue connector to the onboard IDE header
and the other connector(s) to your hard drive(s). Consult the documenta-
tion that came with your disk drive for details on actual jumper locations and
settings.
