10.4.9 : No networking every other boot - Broadcom 5751 NIC

[cell-gfx]

Hi,

 

I have installed my Compaq DC7100 with Jas' 10.4.8 SSE3 install with Semthex 8.8.1 DVD, fully patched and this completed successfully.

I then installed the 'reload koolkal 10.4.9 combo update intel sse3 8.9.1 & 8.8.1', selecting 8.9.1 and this worked also.

I've now got everything working, except for networking. The DC7100 has a Broadcom NetExtreme BCM5751 Gigabit Ethernet onboard.

 

I followed the guide here : http://forum.insanelymac.com/index.php?sho...mp;#entry315849

but OSX freezes during boot at this point :

 

I have checked that my card's vendor ID is in the info.plist file and it is : 14e4 1677

 

Does anyone have any ideas as to how I can get networking running under 10.4.9 on a Broadcom?

 

Thanks,

Cell

Thought the problem was solved : followed this guide... http://forum.insanelymac.com/index.php?s=&...st&p=261280

 

But now every time I reboot, I have to follow the same procedure... reboot once without onboard network enabled, repair permissions, reboot, enable network, load OSX.

 

Not good! Anyone know how I can make the system detect this permanently?

 

Cheers,

Okay, I've got it to the point where as long as I repair permissions before I shut down or restart the PC, I can get back into OSX no problem. If I don't, I get the same locking up problem above... anyone got any ideas?

I have the same problem. I have to delete the extension cache files before I reboot or it won't load the extensions for the 5751. Haven't figured it out yet....

Exactly the same problem here. I find if I disable the card in the bios, boot into osx, then restart, enable it in the bios, it then boots all the way in and works.

 

Has anyone made progress with this? Perhaps there is a way of clearing the cache automatically on shutdown for the time being until a solid solution is found?

You need to move the driver outside of the extensions folder and then edit your /etc/rc file to load it later on..

Working:

Static addressing (w or w/o mac assignment)

Manual MAC assignment (to avoid 00:00:00:00:00:00)

DHCP (only after MAC assignment)

 

I strongly recommend that you install the .kext to a folder other than Extentions (eg: mkdir /System/Library/Extensions2/) then trigger the kext on boot from rc using the new directory.

 

From the CLI:

sudo vi /etc/rc

 

page down to second last line (above "exit 0")

 

Insert (press "i"):

### Start NIC kernel extension ###

kextload -t /System/Library/Extensions2/AppleBCM5701Ethernet.kext

ifconfig en0 ether 00:12:34:56:78:90 [or whatever your Mac is, or whatever Mac you'd like to jack]

### End NIC kernel extension ###

 

Escape, write and quit (<ESC>wq!<ENTER>)

 

 

If the ether commad doesn't take your mac address will be 00:00:00:00:00:00 and you will need to run the ether command again (once booted) or just assign a static IP address (easier).. some cards will crash on the ether command (mac assignment).

Perfect..this has solved my problem.

 

Kextload works, ifconfig freezes my laptop but I can live without a mac for now.

 

Cheers!
