The Aztech Trident PCI288-Q3DII (NX) is the soundcard that is shipped with the Packard-Bell Platinum 6001 machine, amongst others. It provides high quality sound to up to four speakers and has line-in and microphone channels.
Upgrading to Windows XP was more problematic, as WinXP is not shipped with an appropriate driver, nor do Aztech provide a suitable driver. DO NOT use their NT4 driver, as this is highly unstable under Windows XP.
A suitable driver for Windows XP can be obtained from drivers.on-line.net.nz. You need to search for Trident 4d.
