P5B Dlx -> Jmicron SATA or Intel SATA?

post #1 of 9
Thread Starter 
So if one is running a non-raid system, should one disable the Jmicron controller in favor of the Intel SATA controller?

I mean, what gives?

I was bored and messing around with the BIOS earlier and decided to simply *disable* the Jmicron controller completely and use only the onboard Intel SATA controller.

XP booted fine, but said I had to revalidate my copy of windows ...

So after revalidating and all, things are fine ... but what's the deal, really?

Should P5B-Deluxe users leave both controllers enabled? Or just use one?

Is one better than the other for non-RAID systems?

Thanks in advance for any input ...

Well the mobo sata controller is most probably of better quality compared to the standard intel one.

Do some performance checks with both and see if you get a difference in performance.

I reckon they are both the same though

Just figured it out myself ...

I'm not even plugged into anything associated with the Jmicron ports.

The main SIX SATA ports all grouped together on the P5B-Dlx are *all* Intel ICH variety.

The Jmicron SATA port is near the back of the case ... also, the eSATA port is Jmicron domain.

So I guess the answer to my initial question is that if I'm plugged only into one of the six main SATA ports, then I can safely disable Jmicron ... but if I use eSATA or (for whatever reason) the single internal Jmicron SATA port ... then I'll have to enable Jmicron in bios.

I feel better now ...

The Jmicron controller also enables the legacy IDE connector on the board. So if you have and older ATA HD or CDRom, instead of SATA, you would need to enable it as well.

I'm dealing with this right now too. I finally just ordered a SATA DVD burner after trying to get my old ATA CD-RW to work. It worked a couple times. Then I started hooking up two hard drives and it started recognizing the CD-RW as a floppy drive lol. It also takes a lot longer to boot up with it turned on because it goes through detecting all the drives, etc. I say turn it off.

How exactly does one turn it off? I've never really poked around that part of the BIOS since it works fine. I just don't want to see the "JMicron didn't detect any drives" message each time I boot.

If you don't have any IDE devices and don't need to use your eSATA port (external SATA) ... then you just locate the Jmicron on/off switch in bios and turn it off.

Word of warning: You may have to re-validate your windows install, though. I had too.

I see, I'll look around for it, though I didn't see any obvious JMicron control options in my BIOS.
