I have the same problem!!
Well, I explain a little. I had this problem, other with the eSATA controller and POST problems. Intel send me a new motherboard but the same problems continue. I am waiting for a Intel answer now for all the problems.
I confirm that with 1997 BIOS the BIOS setup does not hung (thank you for the information!!).
I have experienced some diferent problems with diferent BIOS versions not only 2000 and 2006 (with these version BIOS setup hungs) about POST, eSATA behaviour and as already said, BIOS hungs.
My system is:
Core 2 Extreme QX9770
4 DIMMs Intel HyperX 1625 Mhz Intel XMP certified (downclocked to 1333 Mhz because this board does not accept 4 DIMMs at 1625 Mhz)
I hope I will have news from Intel early.
Yes, I know. This is the reason I have downclocked the DIMMs to 1333 Mhz. Firstly I had only two DIMMs in the black sockets at 1600 Mhz. But I wanted 2 more GB of RAM so I preferred to buy same chip memories and downclock them. It was the cheapest solution.
If you have news about our problems post here, ok? I will do the same.
Hehe, maybe we are the unique unlucky people with this issue.
I have no news so far. But apart from that I have a problem when booting at first time. I disconnect the cord from the wall every time I switch off the computer, when I connect again, I get a POST stop asking me "Yes" for enter into the BIOS or "No" to attempt with the current values.
I have answer for this from Intel, this is the option called watchdog or whatever in the BIOS I disablee this in the BIOS but now I get sometimes a black screen instead of the POST message. I can say it is not always.
Apart from that, the BIOS issue we have, if Intel is searching to solve the problem if they consider it like a real problem maybe in a few weeks or a few months we will get a new BIOS version. More ore less BIOS updates come after some months, look into the support web page and more or less is like this.
This is my third DX48BT2 motherboard and always problems... the first one I had directly did not work, USB were not recognized, DVD writer neither... so I could not neither install the operating system, Intel change it fastly.
I have already the power bar with surge protection, but I unplug it for two reasons:
1) Power consumption of the red light the power bar has (365 days the red light on, and every year, I think it would add a big amount).
2) The computer is in the bed room so I would have a red light all night.
Maybe are not strong reasons to unplug, but it is what I have done till now.
We hope a fast positive response now from Intel, mainly for the BIOS update problem.
I've had problems with every bios update since 1893.... just decided to give 2006 update a try, and as soon as Vista (x64) started to boot I get PFN LIST CORRUPT blue screen. Neither Profile 1 (1333@ 1.9V) or manual (1333 @1.7V, suggested setting for my modules) works (BOTH worked fine in 1893) and Vista boot time is about 2x-3x longer with 2006 than 1893(running 1066)! Now this is an improvement over previous updates, which wouldnt even run stable at 1066... but thats pretty lame I cant get the 1333 speed I paid for. That and the 4GB 1600 yellow note in the box definitely have me thinking twice about an intel board the next system I build....
I have 2 nearly identical systems and have same issues with both setups so pretty certain its not a faulty hardware issue
Home: Q9550, DX48BT2, 4x2GB Patriot Viper 1333 DDR3, EVGA 8800GT 1GB, 4x 320GB Sata II in RAID 0, 750W PSU
Work: Q9450, DX48BT2, 4x2GB Patriot Viper 1333 DDR3, EVGA 8800GT 1GB, 2x 750GB Sata II in RAID 1, 700W PSU
So I just tried plugging in an esata drive... which crashed windows... and even after the drive was unplugged, Vista x64 still couldnt complete booting without crashing. Thankfully I was able to boot in safe mode and roll back the bios to 1893. This is really frustrating, why can't Intel make motherboards as reliable as their processors?!
