Can one enable turbo mode with acpi_cpufreq driver?

Does anyone know if I can enable turbo mode with cpufreq driver? (acpi_cpufreq)
I was able to achieve it with intel_pstate driver, but do not see any way with acpi_cpufreq. Or does performance governor automatically has turbo enabled?
I am using Intel Xeon E5-2650, which has default frequencies of 1.2 - 2.6GHz, with turbo level of 3.4GHz.

Turboboost is not always exposed to the firmware.

Can't enable DMA mode with JMicron controller

Working with this 975x is like pulling teeth.
Why does the secondary PATA port have to be the Jmicron POS?! How can I get it to just use the intel controller?
DMA won't work for my DVD drive hooked up to the secondary ATA. I have it set to DMA if available, and it keeps using PIO mode.

I suggest that you read all other post about the JMicron issues where lots of things are explained .We have already discussed about showing DMA under SCSI.SCSI doesn't inform you about the DMA.It simply works,or not.
So it's that simple,if your DVD/RW drive read an burn fast, then everything is OK. Don't worry about the DMA.
Yes, I can confirm that also, for what it is worth. I set up my new board some days ago but hadn't really tested the DVD drive yet. Although I felt and suspected everything was normal, I was very concerned after seeing and reading the problem threads on these boards. I have now tested it with a full 4.7GB burn and it took 13-14 minutes on a 4x DVD+RW, which is completely normal. Also, on checking the Nero log I see it reports "DMA: OFF" which is clearly false, but which a lot of people are complaining/worried about. Copying between hard drives (see specs) 'seems' to go at the right speed too. Windows reports 2 minutes when I dragged 3.12Gb across (quick test to see time although I cancelled it half way - not sure of the maths but seems about right from experience)
Obviously Nero (and probably other applications) are NOT able to detect the true access mode of IDE drives under the JMicron controller.
My specs:
P965 Neo-F
2x512MB Corsair 533Mhz
Asus 7600GT
320Gb SataII Western Digital (JMicron)
IDE:
Lite-On SHW-160H6S DVD (master)
200GB (slave) Spinpoint
Bios: 1.5; JMicron: supplied CD - 1.7.1.0 from device manager

Yes.

Possibly by using an Airport Express, but depends on what type of port connection the printer requires.

Opensource ATI can't switch video modes with CTRL+ALT+plus/minus

Hi,
I've updated my system to the new xorg-server and video driver.
The new video driver (xf86-video-ati-6.7.195-1) can't switch video modes with the CTRL+ALT+plus/minus key combination. I use this key combination a lot and before I upgraded to the new driver this worked :-(
Anybody else having this problem?
I know I can use xrandr to change the video mode, but it doesn't exactly do what I want. Xrandr changes the video mode, but also changes the resolution of the screen, while CTRL+ALT+plus/minus keeps the resolution intact (the screensize is bigger than what is seen on the monitor, you can scroll the screen by moving the mouse "out" of the monitor)
Is there a fix/patch that I can try?

It looks like this is the result of the new opensource ati drivers use the new xrandr.
One of the changes is that it will treat the screen section in xorg.conf differently. Browsing through video modes, using the CTRL+ALT+plus/minus key combination, that are defined in the screen section in xorg.conf is not possible anymore.

NB 100, cannot enable AHCI mode. Official driver won't install. help plz!!!

Hi,
Can someone please tell me how can I enable AHCI mode after re-installing Windows XP Pro on the NB 100? I try to install the official "storage manager drivers" but windows tells me that the machine does not meet the requirements.
Please help

thanks for the reply. The article you've linked seems to be for moving a system disk to another computer and the solutions requires physical access to the hard drive + 2 computers??
Also can you please tell me is it true that there aren't much performance differences between Compatibility Mode and AHCI?

How can one use Mission Control with two monitors? Please bring Spaces back

How can one use Mission Control with two monitors. With Spaces I could treat each space as a single desktop.
SyBB

I use two monitors at work and have no issue. I have my mail set to use Desktop 1 and iTunes set to the second monitor of Desktop 1. I have browsers set to Desktop 2 and Fusion and RDC set to Desktop 3.
Two things that may help you. In System Preferences > Mission Control, disable the setting "Automatically rearrange spaces...". This screwed with assigning applications to certain spaces. And the other thing is don't use full screen on apps that support it. This just makes your second monitor superfluous.

Can I change hard disk with SSD drive in Toshiba NB100?

Can I change hard disk with SSD drive in Toshiba NB100 ?
The Hard disc in this model is same size as SSD 2.5" drive?

Hi
As mentioned above: the SATA controller is supported so you will need to use a SATA SSD drive usually it should not be a big problem to upgrade the notebook with an SSD drive in some cases it could be possible that the SSD firmware needs to be updated but this depends on the SSD drive manufacturer
However, the SSD drive is much faster than a common HDD. Therefore you should notice a faster performance

Can I update 2012 mini with sad drive?

can I update 2012 macmini with ssd drive?

Take a look at the video Illaass pointed to, it shows what you'll have to do. If you've never poked inside the innards of a computer before, it looks a bit scary but its pretty easy to do if you view the video a couple times and take it slowly. But I honestly have to say it is closer to a moderate task than an easy task so you may want to take den.thed's advice and find an independant Apple service provider. You won't get this done at an Apple store.
Another possibility is to get an SSD in a thunderbolt or USB3 enclosure. It won't be quite as fast as if it were installed internally but you won't lose much and if you decide against doing the upgrade yourself it will probably be less expensive than going to an AASP.

No. You can install Snow Leopard with a flash drive 10.6.3 installer. However, for Lion you must start with 10.6.8 in order to access the App Store to purchase and download Lion.

Can't enable developper mode on Nokia N9: server d...

Hi all,
I'm trying to enable developper mode for the first time on my Nokia N9 and I get the following message:
Download failed
Can't complete the download.
Connection to the application provider was lost.
Try again later.
I don't know if the problem is on my side or on Nokia server side. Can someone tell me if they are able to download the developper mode additional applications from Nokia at the moment?
Thanks and have a good one!
Solved!
Go to Solution.

I'm scared of flashing the phone... And I'll lose the warranty...
Have you seen this (attachments). There are some files missing...
I talked to my Nokia service center, they told me that I'm not supposed to use the developer mode??? Is that just an excuse because they can't handle the problem? I have nobody to ask and trust here.

Can one use the iphone with car stereo systems as one does an ipod?

My car has a "jack" for mpegs/ipod to interlace with the existing stereo. Is there an accessory that will allow me to use my iphone as one would an ipod with such systems?

Dewey Cheatum,
Apple doesn't make most of the adapters out there. Instead Apple provides the specifications so that other manufacturer's can make products that are labeled as "Works with iPhone".
I would contact the manufacturer of the car stereo to see if they have one that is certified by them to meet the "Works with iPhone" standard. If the radio came with the car, then the dealer and car manufacturer would be the resource to utilize.
This link described how manufacturer's can get their products labeled as "Made for iPod" or "Works with iPhone".

Hope this helps,

Can't Install from CDs with fusion drive.

I have a new iMac with fusion drive. I tried to install Print Shop from CD and was told I don't have enough room. Drive is 75% empty, It must to looking at the flash drive. Any ideas what to do?

In addition to what the others have said, OS X sees a Fusion Drive as a single device called a Logical Volume. The SSD and HHD that make up the Fusion Drive are totally hidden from the application by CoreStorage. So the problem is not that the SSD is full. It must be somewhere else.
