I have received e-mail from Asus, officially and not through usual Support method. Thanks to Gary [from Anandtech] for that! and ofcourse Thanks to Asus… It seems to have solved the problem with performance lag when copying files from or to the devices connected with JMicron, even when you use default driver of Windows XP, the usual “Standard Dual Channel IDE Controller” but I am not satisfied about the BOOT time . . .
It seems as though the when installing the Jmicron controller the default could be DMA/PIO which it must be detected as Ultra DMA 5 in order for these controllers to speed up (with the device/drives attached).
The BIOS for the Jmicron must be set to RAID.
The problem probably is when installing both the Jmicron controller along with the sound drivers, both are using a lot of CPU resources at the same time. You must make sure that one of the drives are set to UDMA mode 5 to have the sound drivers and the Micron Controllers work at an independent process simultaneously.
Please follow the steps below:
1) Please go into the P5B Deluxe BIOS.
2) Set your secondary RAID controller (JMicron one under Advance–>Onboard devices) in the BIOS to RAID/Enabled (even if you only use IDE).
3) Boot into Windows XP.
4) You may continue to use the Jmicron controller driver from the CD –OR– you may use the drivers from the actual manufacturer of the controller chip from Jmicron. You can get these here :-
ftp://driver.jmicron.com.tw/jmb36x
5) Install the JMicron installation package - even when you’re not using RAID.
6) The OS will find the IDE controller.
7) Go to device manager, open IDE/ATAPI controllers tree. Right click each channel and select properties. Click on advanced tab settings. Make sure that each channel is set to DMA Mode and the device that is attached to one of these channels should be Ultra DMA MODE 5.
8) Reboot your system
At this point your system should operate as normal even having the sound drivers installed - The IDE controller speed should also be optimal and you should be able to navigate without any lag. The optical drives should be able to copy files fairly quickly.
Another quick note is that you may need to do another fresh install before trying the steps above.
Please let me know if this works for you.
Thank you for posting this info. In my situation with the P5B-Deluxe-Wi-fi leaves me and many others completely stumped. Further to the boot lag, further problems exists on these boards regarding IDE optical drives-J-Micron.
If you do not start by playing a DVD or auto run a Cd…these optical drives will not work. Example: If no disc is inserted into optical drive and you right click on the drive letter through My Computer game is over and you will not be able to use the optical drive until you reboot and actually start a DVD or CD. Go figure? Can not get to properties without playing a Disc.
Soundmax Audio drivers still have popping sounds and unable to use this board for video editing due to scratchy audio on voices.
As far as I am concerned ASUS owes me either $ for a technician or an updated motherboard that does not have all these problems.
Regarding your steps 1 thru 8 as to fix J-Micron boot times this is not working for me. I do not like your quick note regarding you may need to do a fresh install before trying the steps above. Which one is it? Steps 1-8 either will work or they won’t. Does anyone including ASUS not test anything for longterm before releasing products/;Bios/Drivers/ for stability and fix problems before their releases? FRUSTRATING!
I have all drives currently recognized set at IDE mode in Bios.
In your Step 2 set set “J-Micron Controller Mode to Raid”
booted into windows, my IDE drive no longer found.
Step 4- I stopped there. and returned bios to IDE.You can use the link for divers. I already have the updated ones from Asus site. DO I need to absolutely do step 4 with your link or use the updated J-Micron from Asus site? then I will continue on your plan.

bloody hell, all you care about is the boot time, no wonder you complain its slow. The jmicron is still POSTing, when it shows its message.
ARE all the P5B series effected by V-Droop and the need for Modifications to keep the voltage stable or even close in the V-Core?
This should be quite an embarrassment for ASUS!!
Name goes on before the quality goes in!
“Plus it doesn’t suffer from the vdroop problems that plagued the ASUS P5B series.”

I have normal p5B and it worked kinda ok when i didn’t use jmicron at all. Only problem was that seagate barracude 7200.10 was slow as hell (i think it’s hd’s fault) –>whole system was slow, but didn’t realise that cause my previous pc was from stoneage
After trying to use jmicron, sound went bad, huge lags with mouse and whole system. So can’t use ide on the MB.
Still have to try this fix but this isn’t the way MB should work!! too difficult and too many updates. Think if some company had bought 100pcs these, pretty expensive fix!
Now i did that and the hd read speed got up to 70MB/s!
I also did alot of other stuff like updating drivers etc, but it seems like puttin totally unused jmicron to raid worked. 40MB/s -> 70.
What’s the idea of this setting! This is my last Asus-product
Even so the hd still lags periodically, not sure why..maybe coz the audio-chip
Good site!
