Well, I had osx (10.4.3 with the Jas patch) up and running for about a day.(quite well I might add) and then the on-board USB decided to fail the smoke test. All of the devices work fine, but the motherboard has seen better days, and some data was corruped on the hard drive.

I wasn't happy with the existing mobo to begin with (Asus A8V) I was wondering what socket 939 boards work well with 10.4.3.

Thanks in advance.

I have it on an ASUS A8N-SLI - works well, sound works (both chans), USB.. etc. On Board Lan doesnt work.

I've got a Soltek SL-k890 pro 939 mobo. It works great. Only problem I have is with sound.. it only comes out of a single channel, although i don't know if thats mobo related.

Biostar TForce 6100-939 here. All onboard features except SATA and LAN are recognized and usable, as expected. No quirks. Using Athlon64 X2 3800+ @ 2.4GHz, and one core deactivated to avoid stuttering.

Running on Asus A8N-SLI, AMD X2 4400+:
Working:
Sound
Firewire
USB
ATA
Gforce 7800GT (in vesa mode)

Not working:
Build-in networking
SATA

Running on DFI LANParty nF4 Ultra-D
Don't work:
SATA and on-board newtwork adapters.

have your same motherboard..check if usb is running in 1.1 mode or 2.0, in mine usb ehci doesn't work and i have only ohci 1.1 controller running..

I have the same problem. See log-file fragment below:

USB2.0 was working on mine. when it died, no longer sees the controller/root hub, and is also showing me a lot of stop errors as well Between that and the lost data on the hard drive, I'm pretty sure it was just a hardware failure.

Thanks for the many replies!

I'm writing this from Osx 10.4.3 on my new Biostar TForce 6100-939. They had it on sale locally. Everything is working quite well now. Thanks again for the help.

So basically you were using the same mainboard as me...

I jsut got my copy installed and am also using the tforce6100, has anyone gotten the video over 1024x768? and gotten the lan working? thanx- Mechmess

mobo see sig:

Onboard LAN: not working
SATA: not tested

USB: working
IDE: both controllers work

sound works out of the box
