I just wanted to document a few things.

 

Abit AB9 Pro + 4.2.1 =

 

1.Jmicron sata controller is not working

2.The onboard Nics (Realtek) work but have very poor performance. (Stuttering and slow transfer speeds.)

 

I installed 4.0 and both problems were resolved. This is too bad because the motherboard is listed as supported on the wiki. And 4.0 doesn't offer the nice options that 4.2.1 includes.

 

Anyone have an idea if I should go and buy a gigabit NIC or just wait for the next release?

I have that same motherboard.

 

- The JMicron controller works, but you have to set it to AHCI in the bios, because that's the only mode the linux drivers support.

- I also had a lot of problems with the onboard NIC.  With 4.2, I would randomly lose my shares (Samba crash I think) when reading/writing to the box.  I reverted to 4.0 and that went away, but I still got occassional stuttering (maybe once or twice during a full length DVD).

 

I bought an Intel NIC and just put it in tonight.  Overall transfer rates only improved slightly, but hopefully the better drivers will elimiinate the stuttering, which seemed more like a buffering issue than overal throughput issue.  After I get to thoroughly test it with a couple of movies, I'll try upgrading to 4.2 again and see if that works better.  I'll let you know how it goes.

Sounds good Mikester. What bios are you using? I'm using the latest 23.
