I had tried this BIOS downloaded from abit official site and everything was great, no problem at all, until I tried to burn my files to DVD media...

I'm using PATA internal DVDRW drive which surely have to be attached to JMB363 as it doesn't have another option.
Well... using this official version 12 BIOS (as also known as 12.B09 BIOS), it gives me very high error rate when burning DVD media. From 6 DVD burned, 3 DVD are failed immediately! The chronology is when the first time I start to burn, it will be successful. But at the second burning, I always failed! And it will keep failing if you dare to try again and again until you restart your system, like there is something stuck in the IDE channel after the first successful burning. After you restart, this scheme repeats. So, in brief, one burn, one restart if you want to evade the failure!
I would say that was a 50% (in fact, more!) fail ratio. What a mess!

If you read the point I bold above, it was very suspicious for me from the first time. I did have the same problem when using the previous AB9 QuadGT.
And I thought it highly possible that this problem was caused by the upgraded JMB363 ROM version in the newest BIOS. I never got this problem when I was using 12.B06 BIOS.
So I flash back and downgrade my BIOS to 12.B08 and hope it doesn't upgrade my JMB363 ROM too as 12.B09 BIOS does.
And you guess it right. 12.B08 BIOS rocks. My problem above is story of the past now. I try to burn 5 DVDs and no failure at all with this BIOS.

Really... BIOS 12.B09 or final is a crap for me too. Although it fixes the 1.125 multi, but it's useless to me as I never touch the 1.125 multi.
I just wonder WHY abit engineers might do such mistakes? They fixed one issue, but readded another issue.
First they forgot to restamp the BIOS name in BIOS screen, and now..., IMHO the upgraded JMB363 ROM they provide ruins this new BIOS at all!

Still have a lot to learn for them I guess...
