So far i've installed the base packages successfully. I'll continue when i get home from work.

Installing Tiger w/ External DVD ROM

I have an e-mac with a dud super drive, bought an external DVD Rom Drive, pop the disk in, It mounts, double click install, it says restart to start the instalation, i do, then it boots up like nothings different, no installation, I tried to restart holding down "c" and a weird screen comes up with some "apple basic" stuff and i have to restart I also changed to start up disk option and it didnt work. I'm runing 10.2.8, bought a new mac book with tiger and leopard software, I want to upgrade my good ol e-mac but cant! Please help!
Brad

Bradley Beef,
Welcome to the Apple Discussions!
Is the external DVD Firewire or USB? Only Firewire devices can serve as external boot drives for PowerPC (PPC) macs such as the eMac.
Holding the c key down at startup tells the Mac to try to boot from the internal optical drive. You want the option key, as described in Startup Manager: Select a Startup Volume. (You can also look at Magical Macintosh Key Sequences).
From your post, it does come across that you're using the Install discs from the Mac Book. Aside from the pesky legal detail that the Mac Book software is licensed only for use with the Mac Book, gray label OS X Install discs are model-specific and will only work with the model with which the discs were shipped (not to mention the Mac Book is an Intel CPU and the eMac a PPC CPU). You'll need the retail black-label Tiger or Leopard Install DVD to update the eMac.
Updating from 10.2.8 to 10.4.x will make your eMac feel much more responsive (assuming you have at least 512 MB RAM). There's a handy upgrade guide for Tiger in Gulliver - Tiger Upgrade Guide.

Hi.
You simply can't. Snow Leopard is compiled in Intel binary only.
Good Luck.

Problem to boot to an external cd rom toshiba

Hi,
I can't boot to my external CD-rom Toshiba.
Its name is not present in the boot list.but it work normally when I 'm in windows.
I want to install Ubuntu.so I must boot with live CD and install ubuntu.
Think to help me fastly

And why do you think this should work?
I don't know which notebook or desktop PC do you use but it depends on BIOS support.
Obviously your hardware doesnt support boot-up from external optical disc drive.
What do you need is MS-DOS access. That means you must start your PC in DOS mous and load MS-DOS driver for optical disc drive to have access to it.
Pretty complicated.

Using External CD Rom drive to import music from CD to Itune

I have itunes 6.0 on an XP laptop, and an external TDK DVD/CDrom drive. Itunes imports music from CDs when I use the drive on the laptop, however, only imports links (seem like URL links) when I use the external drive to import music from a CD into a playlist.
I am trying to use the external CD rom drive for importing music into Itunes, but there seems to be a problem, or I have not checked some box or the other. Can someone help??
Thanks

First, Jaguar does not come on a DVD. The standard Jaguar release comes on two CDs. What you probably have is a gray color OEM DVD or a copy that was made for a specific Mac model and will not work with your computer. Furthermore, in order to run OS X on your computer you must first install a firmware update.
You also need at least 128 MBs of RAM for OS X and at least 3 GBs of free space on the hard drive during installation. Your particular model requires that OS X be installed on a drive or partition that is less than 8 GBs. If your hard drive is larger than 8 GBs it must be partitioned such that the first partition is no larger than 7.85 GBs and OS X must be installed in that partition. The drive must also be formatted Mac OS Extended (HFS+).
Furthermore, you cannot boot OS X from a USB drive, only from a Firewire drive.
You will need to get the correct Jaguar installers. You can purchase the right package at www.applerescue.com. Your particular model is compatible with Panther thru 10.3.9. Panther would be a better choice than Jaguar because it is much faster even on your iMac. However, OS X will not be very fast on your computer because it lacks CPU speed and video horsepower. If you continue to install OS X, then you should plan to install the maximum of 512 MBs of RAM that iMac supports.

Using an external cd-rom for re-installing the os X?

hello, i have a problem , my superdrive it`s not working, and i don`t want to replace the unit, i have an external cd-rom an want to know if i can re-installing or re-boot it from the external drive.
please help me,... i need to errase evrything from my ibook, because i want to install leopard.

The drive needs to be capable of reading DVDs to read the Mac OS X 10.5 DVD, and it should be a FireWire drive to use the disk for the installation.

Recognizing external CD Rom

I'm using Organizer, v. 5, but it won't recognize my external CD-ROM--only the one built into the laptop, which doesn't eject disks (so I bought the external rather than replace or repair). How can I do this?
thanks....

It's been working fine for everything else for a couple of years, though I recall that one program had to be teased a little. But Organizer doesn't dream that such a situation could exist.

OS refuses to mount external USB flash drive. Says a piece of OS software is missing.

OS refuses to mount external USB flash drive. Says a piece of OS software is missing. The flash drive (thumb drive) usually lights up but does not go through the flashing on/off that was tyjpical when first inserting it.
I tried an external hard drive and got the same results; that is, no result, as if it wasn't connected. No icon appears on the desktop and no device shows up in the sidebar. It (10.6.8, Mac Pro Duo) had worked perfectly before this, of course.

Hmmmmm,,,,
Disconnected all peripherals. Did a Safe Mode startup and that worked fine. Very limited features, of course.
Started up with the Snow Leopart (10.6.3) disk. Used disk utility to verify permissions and ran disk repair on all three internal HDs. No repairs needed.
Ran Drive Genius and did the same things, as a double-check.
Plugged in the flash drive (thumb drive) and it came up fine (still operating the OS from the Sno-Leop disk).
I wanted to re-start with the disk and bring up the Apple Hardware Test as you suggested. I had lots of kernal panics on a previous machine, a G4 desktop, and has used that at that time (with a 10.2 or 10.4 disk). thought I remembered that you hold the D key down when starting up from the disk and it would open the hardware test, but either I remember wrong or it works different in 10.6 because it was just a normal startup.
How do I get to the Hardware Test on the 10.6 Snow Leopard disk?
Restarted without the disk and the Mac Pro desktop still showed the gray screen with what Apple calls the "prohibitory" sign, the circle with the diagonal line in it.
I decided to load the OS disk onto HD 3 and designate that as the startup disk, which I did and it works fine. The USB flash drive loads properly, opens, etc. just as it should. I haven't yet plugged in the peripherals (scanner, printer, second DVD/CD recorder, tablet, an external drive, or connected to ethernet yet. Will do those one at a time and see if any of them casued a problem.)
Am I right in thinking:
A) HD One might have bad sections. I didn't defrag with Drive Genius (26% fragged) or look for bad blocks, which I'll probably do tonight.
or B) the OS has been slightly corrupted and may need reloading
or C) I have a virus or conflict (though I haven't added anything new lately). I do have the ButtonManager loading problem for Mac. which is talked about on MacRumors site, etc. but the timing of its appearance and this problem don't match.
Apologies for being so wordy; want to get all information that may be helpful. I appreciate your interest.

Installing from external dvd rom

Hi,
Is it possible to install solaris 10 from external dvd rom. If yes then how?
Thanks,
Javed

I just did this on a Sun E420, attaching a SCSI DVD-ROM to the external SCSI connector, so that it's on a different SCSI bus.
Did a probe-scsi-all to see the device.
Did a devalias cdrom to see what that path looks like
Did a devalias dvdrom <path to DVD like the cdrom>
boot dvdrom (worked)
to make the device alias permanent (devalias setting is lost after reset or power down) use nvalias command (like the devalias) and make sure the use-nvramrc? OBP env variable is true. (see online OBP docs).
If you have a x86/x64 system, this won't help.

Yosemite cannot mount external disks

Since I upgraded to Yosemite my IMAC does not mount external disks, even the bright new one I bought
I have also a Macbook Air that I upgraded to Yosemite and these same external disks can be mounted on the Macbook Air.
I have searched on the Apple support community and on the internet and quite some people whom upgraded to Yosemite have the same problem.
I checked the USB specs on both the IMAC and the MACbook Air
IMAC :
     Hostcontroller : builtin userinterface
     OS hostcontroller : AppleUSBEHCI
     PCI- code : 0x3b34
     PCI revision code : 0x0006
     PCI factory code : 0x8086
     Busnb : 0Xfd
MACBook Air:
     Hostcontroller : builtin userinterface
     OS hostcontroller : AppleUSBEHCI
     PCI- code : 0x0d9d
     PCI revision code: 0x00a2
     PCI factory code : 0x10de
     Bus Nb : 0x24
Needless to say that I need the data stored on the external disks.
Thks for helping me out.

I have read that if you turn Spotlight off you will have no problems. Open Spotlight, choose "privacy", click the "+" at the lower left and add what you do not Spotlight to search. Worked for me. I have 2 internal Seagates formatted OS X journaled in an external case.

I have a Canon DC310 camcorder that uses mini dvd's and doesn't have the ability to connect to a computer. How can I get my new Imac to read these dvd's? Will the mini dvd adapter work or do I need to purchase an external dvd rom device? Which device works well with the Mac? Do I need anything else to get the dvd material onto my mac? Thanks!!

No DV port in camcorder. Just a yellow AV port/hole. I did find a Canopus ADVC110 device in a box that was bought several years ago to convert VHS tapes onto DVD's. Can I use this with a Mac? Could I connect a dvd player to the Canopus and transfer the disks onto my Mac? Or, connect the camcorder via AV port to the Canopus and that to the Mac and transfer that way? Thanks again!

HP Envy 15 Won't boot from external dvd rom

Hi All,
My HP Envy is brand new (Envy 15 j151sa). The external DVD drive is brand new (HP dvd600). My model of the Envy does not have an internal CD/DVD drive
I want to boot from a live DVD.
I've read other posts and answers for similar queries and followed the suggestion.
On boot press F10 (BIOS setup) and the Boot Options settings are as follows...
a) Secure boot - disabled
b) Legacy boot - enabled.
c) Changed the legacy boot order to have the USB dvd rom as first in the list.
Save the setting.
Restart the PC.
On boot press F9
Displays the availabe list of devices (3) to boot from as
OS Boot Manager
Boot from EFI file
Notebook harddrive
There is no option to select the external DVD rom drive.
I have upgraded the BIOS to the latest HP recommended version.
I don't know what else to try.
I could really use some help now.
Thanks

Your external DVD drive is operatying as it should.
The best place to find an answer on how to make the live CD is at the Debian forum. The disk you made apparentlydoes not have an MBR bootsector or a recognized EFI partition. Either of those is what is needed for the disk to be bootable and your notebook BIOS must be configured accordance with the choice of format type.
Personally I have always preferred using a utility like UNetbootln to make multiple "live" bootable Linux versions.
I don't bother with the hassle of DVD or CD media any more.
If you have a spare 32 or 64GB usb flashdrive, then you can put an incredible number of versions of Linux and troubleshooting utilities on it.
The economy of scale with usb flashdrive has gotten to the point where a 16 GB usb flashdrive is less expensive that DVD recordable media. Check out the prices at NewEgg.
