I have successfully installed the IPC 10.5.6 on my Dell Dimension 5150.
Kernel: 9.5.0 voodoo Kernel

However, the network card dosen't work.

I have download the 8255 patch AppleIntel8255x.kext. But when i try to install it with the below command(other commands before this one all succeed ):
sudo kextload -v /System/Library/Extensions/AppleIntel8255x.kext

an error shows up:

kextload: loading extension /System/Library/Extensions/AppleIntel8255x.kext
kextload: loaded version 2.4.1 of module com.apple.iokit.IOPCIFamily differs from requested version 2.5

It seem the versions don't match.

Could anyone please help?
Many thanks.
