10.4: Install Tiger via Target Disk Mode Install
Tiger only hintI actually tested this to see what would happen. I have a G3 tower with only a CD drive, and I also have a G4notebook with DVD drive. I put the G3 tower into target disk mode (boot with the 'T' key held down), and I then attached the FireWire cable between the two computers, inserted the Tiger DVD, and ran the installer.

The computer rebooted and I installed 10.4 on to the startup drive for the G3. It actually worked ... and 10.4 tried to boot from the G3 hard drive. I shut down my G4 PowerBook and rebooted the G3.

10.4: Install Tiger via Target Disk Mode
Authored by: xavierbdm on May 03, '05 10:54:14AM

This how I
- installed Tiger (Family Edition, mind you) on my iMac 17"/800 whose DVD player is broken
- installed Tiger on my Pismo whose DVD player was scavenged to equip my brother's grey clamshell iBook,
all this from a PowerBook Alu.

Works great.
So there is a way other than returning the DVD and asking for the CD against a nominal fee.
But you need another mac with DVD player ;-)

I'd advise those with only one machine and no DVD, to get the CDs though, as troubleshooting might require them in a future time.

10.4: Install Tiger via Target Disk Mode
Authored by: dfe on May 03, '05 11:26:13AM

This is a good hint. I had to do this with the developer seeds as my Tiger test machine has a DVD-RAM and could not read the DVD-R discs I burned from my PowerBook 17. Apple did periodically send out pressed DVDs but they were usually so far behind it was hardly worth it.

My main problem with this method is that I like to be able to use my PowerBook when installing Tiger on my test machine. Therefore, I created a few gigabyte partition on an external firewire drive and used asr to dump the contents of the downloaded DMG onto that partition. I then blessed it and was able to hold down Option at startup to boot from it and install Tiger normally.

Note that whatever partition you use for the destination will be completely erased so you may need to first repartition the disk to give yourself an empty 3-4 GB partition. In my case I had purposefully left a few gigabytes of unpartitioned space on my firewire drive for just such an occasion so I was able to use pdisk to add partitions being very careful not to remove any existing partitions I wanted to keep. For the less prepared there are nondestructive repartitioning programs out there.

Would you please confirm what model you started up in the Target Disk Mode? Apple KB article 58583 does not list the G3 tower as being a compute that supports being a target computer. It is only supposed to be able to act as a host computer.

** correction ** 10.4: Install Tiger via Target Disk Mode
Authored by: nohl on May 03, '05 03:51:39PM

I must apologize. In my haste to document this process I neglected the fact that the tower is actually a G4 533 MHz.

I have been reminded that the G3 tower does not support Target disk mode. I am working with others to find more and bring you guys an update.

For those in a hurry, Apple will exchange the install DVD with CD's for $10.

small comfort, but I'll keep digging.

10.4: Install Tiger via Target Disk Mode

From memory certain early G4 and some G3 machines required a firmware upgrade (which only ran from OS 9 I seem to recall) to enable Firewire Target Disk Mode. I encountered this several times.

10.4: Install Tiger via Target Disk Mode
Authored by: da5idonimac on May 03, '05 11:44:01AM

i had the same problem - i solved a bit differently, as someone suggested in the spymac forum:
my computers: imac G4 without dvd, powerbook G4 with dvd

1. insert install dvd in powerbook
2. reboot powerbook holding 't' for firewire target mode
3. connect imac to powerbook with firewire cable
4. reboot imac holding down 'alt'
5. in the appearing screen, select the dvd as boot source (might take a second for it to appear)
6. click on the arrow-button
7. the installation starts

the reason why i chose this method: i rather have the installer running on the machine im an installing on, then on a different machine. i don't know if it makes a different, it just made me feel safer.

Doesn't work with old pmac G4s
Authored by: atallj on May 14, '05 12:58:20AM

I tried to install tiger onto my c. 2000 G4 (AGP) pmac but it didn't work. Doing it your way of booting off the dvd mounted on my mini from the G4 hung during boot, and installing it onto a G4 partition from my mini hung after rebooting subsequent to the install (exactly the same type, i.e. signs, of hang as before). So I have to say that Apple needs to revise their claim of tiger running on *all* G4 AGPs, or at least say in advance for it to run on those machines, it needs blahblahblah, i.e. there's a distinction between saying it can run, and it *does* run.

Note: when calling Apple support, the support person was more interested in determining if I had multiple versions of tiger running rather than solving the problem. It was a bit hard to convince the guy that when only 9Gig of it was allocated for the mac world of the total 130Gig of hard drive space I had for that machine, and the rest was for linux, that I was using it as a mac machine and not just a test bed for determining whether tiger was going to screw me around. In the end, I had to figure out how to install tiger onto the partition that subsequently would not boot. I think of this experience as evidence of the progressive microsoftification of Apple.

OK. Life is normal again.
Authored by: atallj on May 14, '05 12:07:12PM

Well, I've cooled off after the episode with the Apple Support Rep. An interesting artifact of that experience is that I temporary lost my maglite and took an hour to find it this morning. I had it in my hand while talking, and sometime while I was getting more and more angry, I put it down (it ended up in a drawer...closed) and consequently became totally lost. At some point I was beginning to believe in those Phillip Pullman cuts in the fabric of reality that I had somehow pushed my maglite. Anyway, back to tiger.

The issue with the old G4s is that it will not boot with an adaptec scsi card installed, see:

http://macmove.com/#000403

Seth, the person responsible for the above blog, solved it by removing the adaptec card, however I'm wondering now, since tiger is installed onto a partition of the G4, whether the base system can be modified to allow tiger to finish booting. I know that in order to get my orb drive to work with the older versions (10.2 & 10.3) that I had to remove an adaptec driver (don't immediately know which one it is since my G4 pmac is booted into linux at the moment). I may play around with it when I have some time.

10.4: Install Tiger via Target Disk Mode
Authored by: fairfact on May 03, '05 12:32:38PM

Target Disk Mode with a G3 Tower? According to Apple, only computers with AGP graphics can be put into Target Disk Mode (TDM). I tried to put my G4 "Yikes" Tower (a G4 processor on a G3 motherboard) into TGM and was unable to get it to work. Please check your specs and advise how you did this.

Any other ideas re installing Tiger on a PCI-based G4 with just a CD drive (no DVD)

Thanks.

10.4: Install Tiger via Target Disk Mode
Authored by: IanWalker on May 03, '05 01:09:23PM

I thought this was a fairly well-known method - I've used it in the past to install 10.3. I've also used this for troubleshooting to boot a machine that gives me trouble from a hard disc that I know has a good working OS on it.

Something worth knowing: holding down T only works with newer macs (I wish I could recall exactly when this was instituted).

Also worth mentioning, is that if you have a Firmware password enabled, you won't be able to use target mode until you disable that.

10.4: Install Tiger via Target Disk Mode
Authored by: nsapap on May 03, '05 05:23:02PM

Ian,

I've used Target Disk Mode since 2001 in both OS 9 and OS X. I've been able to utilize this function with any Mac equipped with a Firewire connection (going back to 2000 models). I don't know the exact date that this feature became available (sorry!) but have used it almost daily since the Fall of 2001 when I bought my first Mac.

The "T" mode only works with Macs that have Firewire ports.

This also works the other way around
Authored by: hamarkus on May 03, '05 01:48:11PM

You can also put the computer with the DVD drive into target disk mode and then its DVD drive will show up as a drive on any computer to which you connect the computer-in-target-disk-mode to.

At least it worked for me with a 1 Ghz TiBook whose (Super)drive would not read a self burned DVD. A nearby dual 1.8 Ghz Powermac read the DVD but refused to play it because no region code had been set yet (and with no admin rights I could not set it).
Booted up the Powermac in target disk mode (with the DVD already inserted, I think), connected it with a Firewire cable to my Powerbook and the DVD showed up on the desktop and played fine (without asking for any region codes).

Authored by: KenDRhyD on May 28, '05 04:23:54PM

I am having some difficulties with an installation on an older eMac that only has a CD writer drive. I do have two newer model iMacs (15 & 17 inch LCD models), each with a super drive, and i have purchased the Tiger family pack.

When I boot the emac, attach the iMac with a firewire cable and reboot, the DVD drive and its contents do not appear on the eMac!

If I boot the iMac normally and then boot the eMac in target mode (using the firewire cable), then the eMax hard drive shows up, but the installer still wants to reboot my iMac! Odd.

Should not the DVD drive be present on the running system when an iMac is booted in target mode?

So how well does Tiger run on a G3? Does performance seem slower, about the same, or faster?

I'm running Tiger on a 600mhz G3 iBook (among other machines) and it is faster than 10.3. It doesn't have the fancy Quartz graphics effects but that's because of it's graphics card but in general, it is faster. Hope this is useful.

I've been running it on a G3 900mhz/256 iBook, and a 500mhz / 512 / G3 iMac.. Both run fantastic. As mentioned, the iMac doesn't support the glitzy graphics, but it still runs very smoothly.

Overall, i'm very impressed.

10.4: Install Tiger via Target Disk Mode
Authored by: @man on May 11, '05 09:33:47AM

it's kind of a long way around, but i only have (gasp!) one mac in my house (mine) and it's a clunky old g3 imac with a cd-rw drive. rather than lug it to my brother's house and set it up as a firewire target disk, i made a disk image of the dvd at his house then FTPed it to myself (we both have broadband, it didn't end up being that bad at all).

then i backed up my smallest partition of my internal hard drive into an external hard drive, restored the internal drive using the disk image of tiger, booted up from that drive and voila, i could install tiger no problem. it also took less time to install because it didn't rely on the speed of the disk drive.

sure, it's a pain, but i'm more than just a little pissed off that apple was making me jump through hoops because i didn't have a dvd drive. not only could i not just check a simple box on the apple website to get a CD, but then they wanted me to pay ten bucks more? ( i can understand not shipping them, but not offering them at the apple store site? stupid.) i considered downloading a copy of tiger off the internet and not giving them anything, just out of spite.

BrentT, i had quite a few problems for the last few days ion my g3 imac (600 mhz, slot cd-rw). tiger was running incredibly sluggish and i was considering going back to panther or sucking it up and doubling my memory to a gig just to get some speed back in my machine. turns out it was some seriously screwed up permissions which was causing it. everything is fine and quick again.

Thanks for the hint! I used the target mode and I was able to put Tiger on my G3 Bronze PB. My pb works great. In fact it's faster.

I wonder if it is possible to perform a zero-level format before installing Tiger using this technique. Anyone has an input ?

Authored by: kon21 on May 21, '05 12:32:35PM

Can anyone tell me more info on how does this works?
At which point does the optimization happen?
I'm just confused at how does the installer optimize performance when running a say a G5 and installing on a G3 in Target Disk Mode.
