HI,everybody:
I have found many articles for installing Broadcom 5752 driver, and I have tried the different methods for a long time. However, my netcard is still not working now.
My computer detail:
HP xw6400
cpu Xeon 2
4G RAM
Quador FX 4500
Broadcom 5752 (1000M) on motherboard
If someone have successfully installed the type of netcard driver for mac os 10.5, I hope you can send a mail to jhy817@qq.com, and I will appreciate your help.

Carter,
Beijing,China.
