Windows 7 No 4GB (32bit) and in 64bit BootCamp drivers do not work!!!

Hello. I have a MacBook 3,1 (late 2007 model) with 4GB RAM. Under Windows 7 32bit, only 2.96gb Ram is useable and the Boot Camp drivers run fine. How do I get Windows 7 to recognize the entire 4GB? I have used bcdedit /set pae ForeceEnable and that doesn't do anything, still 2.92gb useable not 4gb although W7 recognizes the 4Gb as available? How to enable to fully?
Second, 64bit Windows 7 recognzes the full 4gb but the Boot Camp drivers do not install at all! Hence, no mouse, sounce is crap/unusable, and the rest of the Apple devices are crap. I have downloaded BootCamp 2.1 update but in 64bit Vista, when I run BootCampx64.msi it sells me "Bot Camp x64 is not supported for this model." Hence, the 64bit drivers do not install DESPITE a 64bit OS.
I went to the Genius Bar but the guy was an oaf and didn't know anything helpful. Help please!?!!!
Help please.

Windows 7 is not fully supported as it is not released yet. You might be able to find some Windows Vista 64bit drivers for it but there is no guarantee that it will work.
You are incorrect! I am UPGRADING from Vista 32bit which supports 4GB of RAM with SP1. If you read my original post, you will see that I already tried the Vista 64bit drivers in Windows 7 64bit.
Windows 7 is downloadable from Microsoft and also supported already by Parallels v4 and the latest Fusion.
Hence, my original questions stand: How can I enable fully enable 4GB in Windows 7 32bit? Or, install, with Windows 7 64bit, install the correct Boot Camp drivers?
As I said, when brunning the Vista 64bit Boot Camp drivers in Windows 7 64bit, it says "Vista x64 Boot Camp not supported on this model."
Anyone have any suggestions?

Windows 7 64 bit and X-Fi XtremeGamer - Bass Redirection Not Working (No Subwoofer)

SWindows 7 64 bit and X-Fi XtremeGamer - Bass Redirection Not Working (No Subwoofer)% Greetings,
Today I ugraded to Windows 7 Ultimate 64 bit edition and am having a problem with my 5. surround sound that previously worked perfectly in Windows Vista Ultimate.
I am using an X-Fi XtremeGamer PCIe card and the problem is that I have full working surround sound, but the bass/ subwoofer isn't working.
Previously in Vista I enabled bass redirection in the Creative Console and this would make the subwoofer work. In Windows 7 in the console there is a bass redirection option but it doesn't work. Also in the Creative Audio Control panel there is NO option for bass redirection either.
Audio sounds tinny and I am 99.9% everything is set up correctley, I think this is a driver problem. At this moment I'm unsure if this issue plagues both the 32bit and 64bit versions of Windows 7 or just the 64bit version (since the console launcher is 32bit).
Anyone had a similar problem and cracked it's Apart from this small glitch Windows 7 is great!
Thanks!

WRe: Windows 7 64 bit and X-Fi XtremeGamer - Bass Redirection Not Working (No Subwoofer)h heya, I have exactly the same problem.
running 64-bit windows 7, X-Fi Xtreme Audio sound card, Trust 5. speakers.
the bass used to work in XP because I could enable bass redirection and alter crossover frequency.
these options are now no longer available in the windows 7 drivers (.4.90) and my bass is not working at all.
it is very annoying, there has been no comment from creative than i can find because it only appears to happen to a small percentage of speakers.
basically if someone from creative can't help fix the problem,?people with this problem?will unfortunately be forced to purchase a different brand of sound card because my speakers certainly aren't broken and work with the on-board sound fine.
so if anyone else has the same problem or any advice on how to fix the problem, please comment.

Windows support files - bootcamp, drivers are not working [no sound, keyboard shortcuts]

Hi guys,
I'm using the following version of Bootcamp Version 5.0.3 (464) on MBP mid 2010, wit latest OS on it. I ave installed Windows 7 through multiple errors and had to clean the whole HD after backing the files. The Windows is running fine now, however I think I havent dowloaded Windows Support Files (second tickbox) in the bootcamp assistant when installing Windows (I only ticked the third box).
And now I have tried to download the drviers from bootcamp on USB after formating it correctly, but the USB shows its empty.
I tried the following steps:
I went back into my Mac and opened up Bootcamp, reinstalled all the Windows Support Files (the top box of Bootcamp) and made sure to put them onto an external device i.e. USB/External Hard Drive etc...
I then logged back onto my partioned Windows on my Mac and updated all the Windows Support Files. After that I restarted my computer back into Windows and popped in Guild Wars 2...
But nothing seems to be working. I went to Windows Update smth, and looked for updates found quite a few of them and isntalled all of them, but noting is working - sound and keyboard shortcuts are gone and I cant downloaed the software I want.
Could you please advice on what to do with those drivers. I have been trying for days...

Hi JFFulcrum, thanks for your suggestion. I updated the BIOS earlier and still am getting the same results. Also, I decided to try another old soundcard I had laying around today, a SB PCI 512. And....same result i'm getting with the Audigy. Windows detects both cards, says they're working, but there's no sound. I'm beginning to think I should just RMA the board
if you could find anymore information about those DMA issues, please do post! I have e-mailed gigabyte 3 days ago and they still haven't gotten back to me, so i'm not really sure where to go from here, if it's some setting in the bios, some sort of driver, a bad pci slot or what. ..

Hi,
It might be the graphic driver not compitable with the graphic device. Has there been a change to the graphic driver?
One thing you can try is to uninstall graphic driver and download the latest from Windows Update (if you haven't tried this). Here are the possible steps:
1. Go to Control Panel->Hardware and Sound->Device Manager, uninstall the graphic card driver by right clicking and select "uninstall". Make sure the option "Delete the driver software for this device" is selected.
2. Reboot the system.
3. Go to Control Panel->System and Security->Windows Update, click on "Optional updates" and find the driver for g210 and do the update.

Windows Server 2008 x64 on Bootcamp: Ethernet drivers missing/not working

Hello folks,
at the moment I try to get Windows Server 2008 x64 running on a new Mac Pro (Early 2009).
Installation of Windows Server 2008 x64 (Enterprise) worked out of the box. However, the ethernet drivers do not work. Ethernet cards are not detected and working due to missing drivers.
I have tried several different Intel driver packages. All of them report "No intel card found.". However, the vendor ID of the ethernet card clearly points to Intel.
I have not been able to find a driver yet, does anyone have an idea?
E.g. does someone know the exact chip name? The driver "name"? Anything else?
Thank you in advance,
Stefan

Erik - Thanks for the info!
I use 64-bit applications ... some notes on why:
enterprise supports up to 32GB of memory so the argument to use x64 for memory support is nullified.
... that's not correct. x64 windows versions allow 64-bit addressing, so 64-bit applications created for x64 windows can take advantage of large amounts of cheap RAM as 32-bit applications cannot. 32-bit applications (they are all 32-bit applications in a 32-bit Windows version, even in Server 2008) are restricted to a limited process space of at most 2 GB.
It's true there is a LARGEADDRESSAWARE kludge to enable limited use of up to 3 GB by a user process (and there is an equivalent to this in Server 2008), but this has gone nowhere because it is far more straightforward and more productive for an applications developer to simply go 64-bit rather than invest any engineering resources into a one-of-a-kind kludge for an era that is already past.
Yes, it is true that if you are stuck running 32-bit applications you have less incentive to use x64 windows. But going true 64-bit is a huge advantage in reliability and performance. Given the very low cost of RAM in modern times it makes sense to do so, even in notebook settings that are often limited to only 4 GB of RAM. 64-bit applications in Windows tend to have decisive performance and reliability advantages so whenever one competitor in a given segment makes the jump to 64-bit pretty much all of them must do so.

You may need many other updates to retain compatibility with Lion. I suggest you reinstall Snow Leopard. Unfortunately, you will need to erase the drive first. Be sure to backup your data if you haven't done so already.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. After you finish Setup Assistant will complete the installation after which
         you will be running a fresh install of OS X. You can now begin the update process
         by opening Software Update and installing all recommended updates to bring your
         installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you've already tried a complete uninstall and reinstall try opening iTunes in safe mode (hold down CTRL+SHIFT as you start iTunes) then going to Edit > Preferences > Storeand turning off Show iTunes in the Cloud purchases. You may find iTunes will now start normally.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.

i updated to java 7 and now my yahoo games will not work, how do I fix this?

kathieaross,
click on the Java pane in System Preferences. When the Java Control Panel window opens, click on the Security tab, and set your Security Level to Medium — that will allow “untrusted” applications (i.e. those without certificates from a trusted authority) to run. Press the Apply button in the lower-right corner to confirm the change, then press the OK button to close the window.
Apparently your Yahoo! card games don’t have certificates associated with them, which is why the default security setting of Java SE 7 Update 51 didn’t allow them to run.

I installed Lion and now my MS office will not work, is there a way to revert back my original software?

I installed Lion and now my MS office will not work, is there a way to revert back my original software?

Back to Snow Leopard from Lion install method
Read and print out these instructions, your computer is going to be offline and you wil be cutoff from help until your machine is restored.
Clear the Desktop, Downloads and Trash of anything you wish to keep by placing their files in the respective Documents, Music, Pictures, Movie folders.
If you have a TimeMachine drive, update it and disconnect for the duration of this restore time. It will be your second backup system and will have to be wiped and setup again after successfully going back to Snow Leopard if it was connected to the OS X 10.7 boot drive. If it wasn't, then leave it disconnected without updating to Lion.
Backup ALL your Users folders (Documents, Pictures, Movies, Music etc) manually (drag and drop methods) to a (not TimeMachine) external powered drive (HFS+ journaled formatted in Disk Utility) and disconnect, your going to be wiping the entire disk of ALL DATA. (warning, everything will be gone and not recovered)
Here we go!
Hold c and boot off the 10.6 installer disk that comes with your computer and second screen in just STOP.
Look at the Utilities Menu for Disk Utility.
On the left is the name of your hard drive maker, click it and Erase (format HFS+ Journaled), give it the same name as before, and click Erase...
This should wipe the drive of ALL partitions (GUID, OS X and 10.7 Recovery, Windows if present)
When it's done, quit and install OS X 10.6. Then install all your programs from fresh sources and validate/update.
When you setup a first account, use the same user name as before, this way you can simply drag and drop the content of your previous Users folders from the external drive right back into the new Users folders and everything should work peachy. Links in iTunes to music, playlists and iPhoto links especially.
Update OS X to 10.6.8 using the Combo Update for best results.
http://support.apple.com/kb/DL1399
(Note: If your original machine had 10.5 and you want the free iLife that comes with the disks with the computer, then you'll have to install 10.5 first using the same c boot/erase/format methods as above, then update to 10.6 via the disk, then Combo Update 10.6.8)
Final step optional but highly receommended.
A lot of people use a Carbon Copy Clone of their boot drive to a HFS+Journaled external drive as a "hold the option key" bootable backup in case something goes wrong with their boot drive or need to restore to a previous OS X version.. (in addition to TimeMachine drive for more immediate backups.)
It's not advised to have a Bootable Clone and a TimeMachine partition on the same external drive, as two drives gives hardware protection in case one fails.
