PCIe G5s- are their firewire ports all on the same bus?

Sorry, posted this on the G5 expansion forum but never got a response. I've been looking but haven't found an answer to this. I know it was a major issue to some people that the old G5s had all their firewire ports on the same bus. I was just hoping that Apple had fixed this so I wouldn't need to use up an extra PCIe slot with a firewire card.
So, does anyone have an answer? Thanks ahead of time for any info!

Patrick:
Nope. My understanding of the FW spec is that devices slow down anything after themselves in the chain to their speed or lower. Thus, since the FW800 port isn't after the FW400 ones, the FW400 ones don't slow it down.

And in this corner, Brian:
<div class="jive-quote">Yes, and connecting a DV VCR or camcorder will pull everything down to 100Mbps. This is the reason some systems have dropped frame problems on capture and output to tape.< </div>
While these sound like complementary posts, the confusion is already palpating through this thread. Someone please clarify this for the rest of us. Suggest you use a standard example that includes a hi-speed FW drive, a standard FW drive and a DV deck. Hook them up in the same order to the two ports and tell us what the effects are on the performance of the Firewire bus.
At the present time, there are no PCIe firewire cards. < </div>
I had no idea.
Isn't that just weird? This is the 21st century! Why is there a new data bus structure in our Macintosh without any accessory cards?

I have a new iPad with wifi. When I send messages I can see my sons and my husbands but not my phone number. We all have an iPad and all use the same apple ID as iPad the bill. How can I remove their numbers and add mine?

Add another e-mail account to your messages, so people could reach you on that e-mail from messages. As soon as you are online (if you have wifi only iPad) you are able to send and receive messages. i.e. your son can send you a messages from his iPhone addressing it to your (that additional) e-mail address.

HT1495 I am a teacher and we all have the same itunes account for school. I started downloading apps and it was downloading on others' ipads too. I shut off all the syncing on my ipad but other teacher are saying they still getting my stuff. What do I/th

I don't know if they just got my stuff from before and are just seeing it now or if they still are getting my information. I don't have anything to hide but it's awkward knowing other people are seeing all you are downloading and even messaging. I want to talk to them more and know exactly when and where they are receiving the information but I haven't yet. I talked with one teacher and she thought they just have to turn off the syncing or automatic downloads on their ipads. Will that stop it?

Turning off automatic downloads will stop the other iPads from getting your downloads. You should all do this on each of your iPads.
Settings>iTunes and App Store>Automatic Downloads>Off.... Music, Apps and Books - All Off.
As far as Messaging, if you are all using the same Apple ID, you will all receive the same messages because Messages uses the Apple ID email address as the means by which you are contacted. Apparently all of the devices were set up with the Apple ID, which is fine, but you should all associate a new email address on each device where you can be reached. One device can keep the Apple ID as the contact address.
Settings>Messages>Send and receive>Add another email address.
Add your own unique email addresses in there. Apple will verify those addresses. Go to the inboxes of those email addresses and read the email from Apple. Follow the instructions in the email in order to finish the verification process.
Then go back to Settings>Messages>You can be reached by iMessage at ..... and remove the Apple email address from all but one of the iPads. Or you can just uncheck the Apple email address as the contact address, select the new email address, and check the correct email address as the "start new conversations from"
You will now all have your own email addresses as the address at which you can be contacted with the Messages app.

My family of four are all sharing the same Apple ID so that we can share the calendar. Is this a disadvantage?

My family of four are all using the same Apple ID for our iPhones as well as several iPads. From what I've read, the preferred practice is for each family member to have their own Apple ID. We need to share our calendar and do not want to lose access to our music. What do you recommend at this point?

Hello phoge,
Thanks for the question. After reviewing your post, it sounds like you want to share music and calendars with the family. I would recommend that you read this article, it may be able to help you isolate or resolve the issue.
Family Sharing - Apple Support
Once you’ve set up Family Sharing, all the eligible songs, albums, movies, TV shows, books, and apps ever purchased by family members are immediately available to everyone else in the family. And, of course, so are new purchases.
Family Sharing creates a family calendar where everyone can view, add, or change events and appointments, and they can also get an alert when something changes
Thanks for using Apple Support Communities.
Have a nice day,
Mario

I don't think I see my situation addressed. I have one mobile me account and a separate appleID for purchases. I have 4 devices and my wife has two. Right now they are all using the same mobile me account to sync just the calendar and address book.
1.) I want to add email syncing for my 4 devices and email syncing for my wife's two devices separately, but we want to sync and share the same calendar and address book. Is this possible?
2.) I also have 5 different calendars, one for work, one for home, one for... etc. Is there a way to have different devices only sync certain calendars and not others or is it an all or nothing deal?
Thanks in advance for any tips!

To begin with, I would like to try to explain Apple's confusing nomenclature in regard to iCloud.
Apple have called the whole cloud thing iCloud, there are a number of features under the iCloud umbrella, some of which require their own login. iTunes is one of these, another is what Apple have unfortunately also called iCloud.
You can use the same Apple ID (account) to login to both iCloud and iTunes, but you don't need to and often users will login to each service using a different ID.
The part that you need to remember is that the services available when you log into iCloud are completely different and unrelated to those when you log in to iTunes. Your iCloud login enables mail, contacts, calendars, find my phone, Back to My Mac, Documents & Data sharing and photosstream, it does not affect any of your iTunes services.
To avoid confusion when discussing your problem, when I mention iCloud, I am referring to the services under the iCloud login, Whereas I will refer to the whole cloud thing as The Cloud.
Generally speaking it is not a good idea to share an iCloud account between different people, it often results in contracts, calendars et cetera being deleted by others. Saying that however you can add secondary iCloud accounts to your devices at settings> mail, contacts, calendars. Secondary accounts do not have all the features of a primary account, but are often very useful. Because you can enable or disable each individual feature of an iCloud account, you can cover almost any situation by using secondary accounts.

Update to IOS 6 has been a nightmare. Facebook would allow me to save pictures unless I granted access to my foto album. Does this mean my pictures are going be planted all over the web? The safari keeps crashing and loading is slow.

Back up all data.
Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
When the OS X Utilities screen appears, follow the prompts to reinstall the OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

I updated my Iphone4S this week to the newest IOS 7.1 and now everyone who calls me says the calls are not clear, muffled. Is there something I can do to clear this? 4 people in 4 different states that called me all said the same thing.

3 different iPhones on same apple id are all getting the same calls

My family and I are all on the same apple id with our iPhones. Right now whenever one of us gets a call, the other 2 do to. I was wondering how to get rid of that.

When I import videos taken with my iPhone 4S to my Windows PC some of the landscape videos are upside down and all of the portrait videos are rotated 90 degrees. It makes a difference depending how I hold the iPhone when taking videos. Help!!!

When I import videos taken with my iPhone 4S to my Windows PC, some of the landscape videos are upside down and all of the portrait videos are rotated 90 degrees. It makes a difference depending on what position I hold the Iphone when taking videos. Help!!!!

Sometimes syncing will have problems with very large video files like this. I'm not sure you will be able to overcome this, but if the videos are important enough you may consider purchasing 3rd party software such as Touch Copy to transfer them.

I have an iPhone, an iPad, 2 iPad mini's and 2 iPod Touch's that all share the same apple id. I want to separate the iPhone so that texts are not seen on the other devices but I still want them to have the iMessage ability. How do I do that?

Why contacts birthdays are being showed in iCloud calendar all with the same age (11 years)??

Why contacts birthdays are being showed in iCloud calender all with the same age (11 years) ?? There is a solution to solve this problem ??
Thank-you

I cannot agree more with your comments! What a way to frustrate your customers!
I have been having an issue with iCloud on Mac where it kept asking me for my password and sometimes would, sometimes would not continue to access my iCloud mail. Today it just refused to connect to iCloud mail.
I looked in the Mail, Contacts and Calendars in my MacBook Pro settings and discovered that 2 iCloud accounts were present. One with my original Apple ID (a gmail address) and a second with my new iCloud email ( an @me.com address). Having deleted the second account, using the new @me.com address everything is working fine.
So from my viewpoint when I moved over to iCloud I was asked to sign in with my Apple ID (the gmail address) then to create an @me.com address. However, as far as I can see all sign ins to the new @me.com account on Macbook, iPhone and iPad need to be done through the old Apple ID (the gmail address). Is that confusing and just plain crazy???
Further, after creating the new @me.com address I soon found out that this is apparently now forever bound to my old Apple ID and cannot be changed. I mean why can't I delete the iCloud account and start anew with a different @me.com address??? Also, as everybody using iCloud must create an @me.com address why on earth can I not get rid of my old gmail address and have my entire Apple ID accessed through the new @me.com address? Creating a whole new Apple ID will not solve this as we are unable to transfer purchases between accounts.
Apple products are great IMHO, but they do seem to not think things through in a very big way sometimes......

We have three Apple devices. They are all have the same name and are on the same apple ID. We would like to back up our Notes to the cloud. If we each create our own Apple email address will they create two separate Notes flies on the cloud or merge?

We have three Apple devices 2 IPhone 4's and one Ipad2. Only the Ipad2 is running the latest OS. They are all have the same name and are on the same apple ID. We would like to back up our Notes to the cloud. If we each create our own Apple email address (we don't have one yet) will they create two separate Notes flies on the Cloud or merge them?

Welcome to the Apple Community.
Separate Apple ID's will result in separate notes. However when you first start with separate ID's unless one of you erases the notes you have, you will both start off with the same set of notes, but from then onwards each set won't sync with each other.

Hi all, I have four kids and they are all using the same itunes account.......Is there something I can do so they don't all see eachothers imessages?

My kids are using 4 different ipods with the same itunes/apple account, Is there something I can for them to use facetime/imessages withouth seeing eachothers messages? I mean set up different accounts for messages?

- Create a NEW account using these instructions for each user. Make sure you follow the instructions. Many do not and if you do not you will not get the None option. You must use an email address that you have not used with Apple before.
Creating an iTunes Store, App Store, iBookstore, and Mac App Store account without a credit card
- Us the new ID for Settings>FaceTime and Settings>Messags>Send and Receive and Settings>iCloud. Continue to use the common ID for Settings>iTuns and App Stores.
