This is a note for how I install iPC OSX86 on my Dell OptiPlex GX620.

Hardware Spec:1. Intel� Pentium� D CPU 3.40GHz2. NVS290 256M Video Card3. Intel Corporation 82801G (ICH7 Family) AC'97 Audio Controller [8086:27de] 4. Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express [14e4:1677]5. PS2 Keyboard & USB mouse

Here is the list of options during iPC OSX86 10.5.6 installation* Kernel : 9.5.0 Voodoo* Video driver : NVDarwin 256M * Chipset driver : Intel ICHx SATA driversLegacyAppleIntelPIIXATA* Audio driver :Other Audio Drivers -> AC97 Audio* Fix and Patchers :Seatbelt.kext 10.5.5* PS/2 Device Support :PS/2 Keyboard Fix

After installation, audio & network won't work. The following are the steps I use to fix those problems.

1. How to fix Audio problem : Edit or add to /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97AudioIntelICH.kext/Contents/Info.plist with the following text

<key>ICH7 AC97 Audio</key><dict><key>CFBundleIdentifier</key><string>com.apple.driver.AppleAC97AudioIntelICH</string><key>ICH Type</key><integer>7</integer><key>IOClass</key><string>AppleAC97AudioIntelICH</string><key>IOPCIPrimaryMatch</key><string>0x27DE8086</string><key>IOProbeScore</key><integer>10000</integer><key>IOProviderClass</key><string>IOPCIDevice</string></dict>

2. How to fix network problem : - Download and Install the BCM57XX driver installer from http://www.insanelymac.com/forum/index.php...st&p=989345After the installation of the BCM57XX, the network can be enabled; however the MAC address will be all zeros.To fix the mac address problem, create /setmac.sh with the contents

------- File Starts ----------------------------#!/bin/shsudo ifconfig en0 ether 00:e2:e3:e4:e5:e6exit 0-------- File Ends ------------------------------

Then type the following commands under terminal.
