Boot from usb mac g4

Any ideas? Hi, trying to use these instructions to revive an old powerbook g4 laptop with broken diskdrive using a usb hard drive. Ah, I realize there was more to come after hitting space bar. I gave up after dozens of attempts…. If I can only find the cable…. I was hoping to get a definitive answer from this forum, but I think the instructions need a bit more clarification in some areas, this is tricky stuff for non-pros!

I think the powerbook firmware is damage. Do you know how to instal the powerbook g4 firmware through the Openfirmare comand line? After lots of failed attempts with the USB keys and drives, I ended up formatting the internal HD with a partition big enough to restore Leopard. From there it worked flawlessly.

I resettled the pram etc too. I just got the computer off eBay so there is nothing but panther Formatting the hd drive works? No need to point to BootX or anything at all. This made the trick after hours of experimenting with other parameters. Any idea? I am very interested on learning how to do the same, Shora.

Could you please share the details? I will very much appreciate it. Thank you. Thank you! This was a long shot but I was actually trying to boot the installer from a usb flash drive and also install the os to the flash drive. I used my fathers new MacBook Air to restore the installer from disc onto the flash drive. He said that some later Open Firmware based Apple machines allowed you to do this but not mine.

My internal hdd and internal optical drives are broken, this is the reason I tried this method. My only option left is to install another internal hdd and run the installer through firewire. But the hdd currently inside was only 2 months old before it broke and my technician said that it was probably a fault elsewhere in the machine that caused the extremely short life span of this new hdd.

I think it is a new machine guys.

Meanwhile, I have not been able to startup from the USB yet, and I am pretty sure that the solution has to be replacing the damaged internal HD. And even if successfully booting from the USB flash memory was possible, if the internal HD is really dead, you can not get much farther than confirming that you have to buy a new drive. Obviosuly my copy of OS X install dvd was permanently damaged and there is a risk to damage the superdrive itself, but well, these are the risks of fixing it in on your own, I guess. Hi, i did everything that you have told in this forum, but i cant find a way more easier than this steps: 1.

I create a new partition in my g4 disk of 10 gb 3. Restart my g4 and I have press Alt key before the sound of beginning 5. Chose my leopard image to boot it 6. I just want to reach through the interwebs and kiss you or, ahh, buy you a few drinks haha. Then I saw your post and tried it, booted straight in!

Boot Mac mini G4 from USB

Genius, thanks! For those respondents who reported getting a crossed circle — I had this problem too. My next mistake was to format my memory stick in GUID. You need to format it using Apple Partition Map as stated above using the option button in Disk Utility. I used the Disk Utility restore option on the same This fixed it for me. Hi, I am having difficulty following this guide. When I follow the OF, type in all that stuff above, etc etc… I get nothing.

Please can somebody help?????? This works. One of the things that i got stuck on was that i was using a USB3 Stick. OSX was seeing the USB once it was fully loaded into the operating system — i was able to complete most of the steps; but i didnt realize that it cant see it after the Cmd-Opt-O-F terminal screen.

Just want to reiterate this and this is why many are on this page. Not a bootable image from super duper and such. It could work…but if you get an authentic installer dmg, it should definately work! I just get stuck at an Apple logo with the spinning wheel forever. The USB drive does flash for a couple of minutes as it seems to be loading files but then it stops and it sits there just spinning eternally.

Neighbor was throwing out an old mac and I said I would take it. I was able to get an install disc a version just higher than what was said possible for the laptop but that others said will still function on usb. Thanks, Bradley! This will rescan the USB bus. I spend 4 days to fix the powerbook, but then I found this instructions! Can you add a download link for leapord Thanks so much.

I was pulling my hair out with is old rig I found! It ran decently actually considering it only had k ram?! Beautiful screen! Abit different from DOS for sure. But yea.. So ya your little devalias detail here I just found showed me the right path and boom the dir command actually worked and there was BootX! Like 5 old accounts have been erased hd wiped clean for a fresh Osx Thanks to all! Please write to my mail or here. I have read all the comments and still nothing. How can you find the directory if using transmac to make a osx boot usb? As i dont have other mac to do this. I was fighting with this for DAYS.

I tried like 6 different syntaxes for the dir and boot commands, tried aliasing, reading dev trees, NEVER got anything. That is the Then I just thought:. Hope this helps somebody running modern os x like high sierra to make bootable USB leopard install sticks. Well I tried the method above, but there was something bugging me, I did a Leopard USB stick, but I did it under macOS Sierra, in an intel machine, so, after thinking a lot, I was wondering if that could in any way affect the result.

Here is the moment of truth. If this step does not work, I have had very limited success getting a machine to boot off USB2. In Open Firmware, type devalias, and you should get a list as output. Again, if you see this, I have not had this fail yet. See where this is going yet? You should get an ok back. Type printenv boot-device, and you should see the change displayed already.

Bootable USB drive on iBook G4

For those of you who have trouble; Is your system blessed on the external drive? Here is the difference; A disk requires a drive to operate, and that is two devices. If you read the below definition, it implies that there are TWO devices.

A device that reads data from and often writes data onto a storage medium, such as a floppy disk. This has been possible for quite some time, at least since If I'm not mistaken, this is how they do software restores at Apple retail stores, though I'll bet they use firewire whenever possible. Thanks, Nate PS I have the enclosure, but my backup drive is dead, so im trying to figure out whether i should just get a firewire or 3x interface external drive instead. It's a distinction that has no real meaning.

A flash drive is conceptually two devices.

mac mini g4 boot from usb

It's the storage media and the logic and electronics that know how to invoke a state change to store and retrieve data thereon. Just because they happen to be in the same package doesn't really invalidate it. A hard nee fixed disk drive is only a single device as well. I found the following interesting anomaly when attempting to boot from my USB 2. First I tried to make a clone of my Mac's drive using RsyncX. While it appears that the synchronization process was successful, I found I was not able to boot from the remote drive as I expected it's well known that booting from an external USB drive isn't supported on Macs.

I then tried, as the comment suggested, making my backup clone with SuperDuper!. Somehow, my Mac was actually able to boot off the USB 2. I don't know exactly what SuperDuper! I'll provide my system information in case it helps someone figure out why this worked. Powerbook G4 12" PowerPC 1. Hmm, same machine here, well, almost: 12" Powerbook, 1. Made a clone with SuperDuper 2. Looked good, almost everything got across oK except, thankfully, for the virtual memory partitions;- , but no-go.

Not with option at startup, nor selectable in the Startup Disk Panel. I did the backup with the formatting option and the permissions repair enabled, but that shouldn't do any damage. So, what am I missing here? Not so easy as it makes it sound.

Install Mac OS X 10.5 Leopard via USB on PowerPC Macs

So I created my own custom copy script in superduper, to exclude my the folders that contain large amounts of data i don't need backed up. This cut down the size to something that fits. Superduper says it did it all, but alas, i cannot get it to appear in startup disk panel, or by holding option at startup, or even with the older Open Firmware bit.

I have a G5 quad powermac, SuperDuper said at the end of the process that the drive was made bootable, but the SuperDuper website is clear that this should not work on a USB drive. After the copy was made, i noticed that the number of files copied was a little less than the total number of files, whatever that means. Only the computer hard drive showed up with the system. After I read this hint, i tried holding down the Option key and restarting but it didn't bring up the external disk partition--the only choice that came up was the computer hard drive system folder.

I tried it twice. I may be doing something incorrectly. I replaced the iBook hard drive and didn't have a CD version of Tiger. The external drive is an old USB klunker. I did find that the DVD drive you use makes a great difference. I have three drives that would not boot my iBook. I am using an imac. I need to wipe the drives on several Macs the school district is getting rid of and some of the CD roms don't work.

Your Answer

I copied the OSX disc to my drive and tried to boot from the flash, but it doesnt see it. It only gives me the arrows and sees no drive. Any ideas? I'm not sure how SuperDuper would work in this instance. Hi all!

Welcome Image and Text

Here is my "success" story I had a PB G4 with a dead internal hd, and I have bought an external usb 2. I was told by apple tech support, that booting off the external drive is impossible on g4 computers. Then, I have stumbled upon this site, and with SuperDuper, I have made a complete backup of the neighbour's mac mini.

I borrowed the mini, did the backup, and in SuperDuper, all of the booting related options were greyed out. I have tried booting the mini from the external drive, and it did not work. Even if i held down the option key, the drive did not show up in the bios. I wasn't able to select it as a startup disk, either. Then, I was curious, how would my PB react to this new situation with a -supposedly- bootable version of And, tadaa, as I went into the bios, the drive showed up! I was able to boot the system, and I can use it now, it's not really slow at all for general usage. Only the booting is slightly longer than usual.

I didn't really notice anything bad, all the new hardware parts, airport, etc were detected instantly. It is working fine, however, there are strange things. Sometimes, the drive doesn't appear in the bios, but boots. Sorry for the long post, and the bad english. Older Macs may need their firmware updated to the last version available for that Mac model, and not all USB drives might boot.

I found out that It was slow, but not impossibly slow. However, as I expected, I couldn't select the drive's OS Some people have said it's a limitation of the firmware, or Open Firmware, but that doesn't appear to be the case, unless it's a few Mac models just prior to the Intel-based Macs that can't boot A late clarification to my post above: I later found that OS Hi Mike, Thanks for the hint. I have two problems which I need your help on. I'm 3 days old using Mac. I'm looking into upgrading to Tiger or Panther as How do you managed to install Tiger without the CD?

Did you copied from your old hard drive? Another problem is the USB drive, it doesn't seem to detect anything I put into it. When I plugged in the external drive or the SD card via USB, I get an error saying something like "there are no readable volumes" and prompted me to repair or initialize it.

What should I do? Please help as I can't afford to buy another Windblows laptop. Many thanks in advance!!! Once you see your new OS you will need to reset your firmware so it doesn't try and boot from the USB drive anymore. Keep holding this until you hear three "Bongs". Once you release, the Mac should boot normally into your new OS! So if you have Leopard, you can boot off of USB2. About time I'd say. Screenshots and more information here: link PS: SuperDuper Leopard backups are not yet bootable as of 2.

There are several posts in this thread that refer to "copying" an installation to another disk, in order to boot from it. It will not boot. The only way to do it is with a program that knows how to make a copy "bootable". So unless you're using one of those utilities to clone your working OS X installation to another drive, it's virtually certain that you'll fail. Also, from reading this and another hint on the topic, it sounds like there are two other things that might make some difference: 1 When formatting the drive you want to clone TO, don't check the box labeled "Install OS 9 drivers", and Good luck, and post back when you discover tips or tricks that seem to work for you!

Okay, I kinda get how to do it. But if someone out there can give me the answer to these very basic questions I think I may have found success Does this work for Imac G3 mhz? I'm sure I'll have a ton of questions after these two are answered. If it is possible, it is easy. To start from a USB storage device that meets the above requirements, connect the device, then select it in Startup Disk preferences.
