I have just installed Zephyroth leopard 10.5.2.rev2 and for the most part all went well except that when I was finished and before I get the desktop I get an error message about the RTL8187L.kext not loaded. The message is
System extensions cannot be used
/System/Library/Extensions/ rtl8187.kext was not improperly installed.

I changed the ownership and permissions on the extensions folder but that did not help.

Has anyone seem this with their install?

System
Asus: M2N32-SLI Deluxe MB
2 gig DDR2 memeory
320 gig SATA HD

In the mean time, I will reinstall !
