Does arch support booting from an external firewire cdrom drive?

as above?

If the mobo provides that function through bios provisions the arch system should boot.
EDIT: There may be issues with udev and mkinitcpio to ensure the boot sequence is not terminated by the udev detection.

Can PB boot from an External Firewire Hard Drive?

Can I set up an external firewire hard drive as an emergency boot drive, in case my internal drive goes south? Anyone have utility software recommendations for setting up boot drive or mirror drive, in addition to OS X's Disk Utility? Thanks.

Photon2:
Yes, you can set up your external firewire HDD as an emergency boot drive.
Here's what you need to do:
1. Your HDD must be formatted Mac OS Extended (Journaled)
2. (Optional) I suggest you partition your HDD so that the first partition is roughly equivalent to the size of your internal HDD. The rest can be partitioned for other uses. (See Dr. Smoke's FAQ Backup and Recovery) For step-by-step for formatting and partitioning please post back).
3. Use SuperDuper or Carbon Copy Cloner to make a bootable clone of your internal HDD to the external firewire HDD/partition.
Please post back with further questions or comments.

Booting from an external firewire drive

I bought an external hard drive (Western Digital, 320 gb, firewire). First, I erased the disk and formatted it as Mac Os Extended (Journaled).
I cloned my internal drive (using SuperDuper) on to the new external drive. My goal is to have an alternate bootable drive in case my internal drive fails. However, it will not boot on it even though it may be selected as the startup disk. And will not come up as an option when holding down the option key while booting. I've read about a similar problem that was posted but the solution confused me. Can you give me a solution to this problem?

First you should prep the drive correctly as follows:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, select the button for Zero Data (single pass) and click on OK to return to the Erase window.
6. Click on the Erase button. The format process may take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
After formatting has completed select the volume you must created from the left side list, then click on the Restore tab in the DU main window. Drag the new volume to the Destination field. Drag your startup volume from the left side list to the Source field. Click on the Restore button.
After cloning has completed quit DU. Open Startup Disk preferences, select the new volume and click on the Restart button. Your computer should boot from the external drive.

Installing from an external usb cdrom drive

I am able to boot an external usb cdrom drive but I cannot figure out how to mount that usb cdrom drive to complete the install.
My boot command is:
arch-scsi NEEDUSB=auto
I cannot run loaddisk, as it does not find the usb cdrom, so I cannot load the addon utilities (thus I cannot modprobe usb-storage).
I can run /arch/setup but when it gets to package selection, I am unable to select the CDROM source. This machine is not on the net, so I cannot do a ftp install.
Has anyone else installed ARCH using an external USB cdrom drive ?
Does anyone have any suggestions?

Thank you Xentac for you help. I looked up the bug report and understand the problem. Now how do I proceed from here?
Any suggestions on a work around? Should I rebuild the 0.7 beta disk with additions to the initrd? Eventually, I will need to install Arch on about twenty standalone systems. They do not have cdrom's in them, and are not on a network. Sounds like I may have to open up the units and plug a cdrom in for the install
I was thinking of cloning the disk (i.e. open up unit, take hard drive out, put in another system and clone), but it has been pointed out that doing a basic install is a good way of testing the hardware. It doesn't take very long and we have to do testing of our software anyways.
I open to suggestions!

Can the iMac G3 with Panther boot from an external FireWire drive?

It does have firewire. I am worried that if my internal HD fails, I am going to be SOL. Sooo... If I install just Panther (full retail) on a new internal HD, will i be able to boot from it? How about if it is on an external FW drive? I DO NOT have the original install disks that came with the computer.

If I install just Panther (full retail) on a new internal HD, will i be able to boot from it?
Yes. Verify that the computer's firmware is up to date first.
How about if it is on an external FW drive?
Yes.

Can I boot from an external Firewire drive?

I have restored my internal system drive (27GB) to a 100GB partition on a 300GB external FW drive (as a backup).
Using System preferences I changed the startup disk to be the clone & rebooted to test.
No start and the only way to get going again was to turn the FW drive off & reboot.
Is it possible to boot from a FW drive?
Should a drive as described be bootable?
Any thoughts will be appreciated.
John

Thank you all for your input.
After some trial & error (& little sleep last night) I have made some progress:
Further research suggested that:
1. there may be a hardware issue with my Ex FW case (it has a Prolific PL-3507 chip)
2. Tiger (10.4.x) behaves differently from Panther (10.3.x) and possibly different versions of Tiger may behave differently
Also I have previously successfully used DU to move my OS from a 30GB to 120GB disk (both internal drives) under 10.3.9. This disk will boot when placed in a ext FW case.
I concluded that under 10.3.9 at least my case was OK & Apple DU was OK when run from the boot volume.
I also checked the clone made using DU under 10.4.3 by taking the HDD out of the FW case & installing it internally in my Mac - it wouldn't boot so DU hadn't made a bootable clone - it was never going to boot internally or externally. Ever.
Next step - SuperDuper! - worked perfectly - backed up & booted no fuss, no worries.
This confirms that the Prolific PL-3507 chip will boot an external FW disk under OS X 10.4.3.
I then referred to Lee Cullens' posts as quoted by Matthew Whiting (with a link above in this topic).
Lee has the answer (at least for my hardware/software configuration). For Apple's DU to produce a bootable clone it cannot be run from the disk which is being cloned (ie 3 volumes are needed
1st to boot from & run DU from
2nd to be cloned (the vloume to be backed up)
3rd to be colned onto - the backup
I tried DU from the boot disk again to "prove" it wouldn't work. While it appeared to clone correctly Permissions were all messed up & after over an hour of "Repairing Permissions" I gave up. The volume wouldn't boot even though system preferences saw it as a bootable volume.
I then ran DU from another volume (the one made using SuperDuper!). After verification (but not repairing permissions as I didn't want to potentially waste another hour!) it booted fine from the ext FW drive. I did however uncheck "Ignore Ownership" after Cmd-I on the volume from the desktop.
I conclude:
My hardware is OK (& probably others who may have similar issues)
Apple DU can make a bootable clone which will work on an ext FW drive PROVIDING 3 volumes are used - boot with DU on, from & to. Suitable for a bootable backup but a bit fiddly ( also free & regularly updated by Apple)
SuperDuper does the same job with less fuss (don't need a CD or 3rd volume + other features). As noted by Matthew basic cloning is free but I think the shareware cost will be worthwhile ($US27.95)
SuperDuper! here: http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
Thanks to all for their input.
I now have an answer that I'm more than happy with.

T430s: boot from an external USB DVD drive

I wanted to change boot sequence to boot from external DVD drive to install Win8. To access the BIOS I hit Enter (empty password I guess) but in the BIOS everything is greyed out: I can't make any changes. What is going on?
Solved!
Go to Solution.

@kaja69...
As Rich has stated, you have a supervisor password set, and as Jin Li has stated, there is no default password.
For information on the various BIOS-level passwords, please see your T430s Hardware Maintenance Manual (manual pages 36-38).

Can you boot from an external USB hard drive? (Neo2 Platinum)

As I'm tempted to get a 160Gb drive for Linux and AMD64 XP installations. But obviously it needs to beable to boot from it.
Thanks

I read a post recently about booting from a usb memory stick - I assume the principal is the same. You need to make the usb drive bootable, in the same way that you would make a cd or a diskette bootable. In the example given about a usb memory stick, they suggested copying the contents of a win98 startup disk onto the memory stick. Then, run 'sys.com' on the drive letter of the usb stick from the startup disk. Then, enable usb legacy support in the bios, and access the boot order to tell it to boot from the usb or legacy, I'm not sure which.
What you're in essence wanting to do is to copy the xpcd to the usb drive, so the format and files, etc., are the same. Then, follow with the usb legacy stuff, etc....

Booting os x from *partitioned* external firewire drive?

Hi all,
my internal hard disk (on a 12" powerbook G4 867 mhz running osx tiger 10.4.10) has started acting weird (many people are reporting failing hard drives, and I'm assuming mine is failing too), so I'm preparing for replacing it with a new hard drive.
I've backed up the drive to an external firewire drive (LaCie portable 80 GB firewire drive "Design by F.A. Porsche") using Carbon Copy Cloner with the option 'make bootable' selected.
PROBLEM: I can't boot OS X using my clone on the external drive.
I'VE TRIED:
1. holding down Command-Option-Shift-Delete while booting to bypass the internal drive. (This didn't work: I saw an os 9 icon blinking/alternating with a question mark for a while, and then the computer booted from the internal hard disk.)
2. holding down Option to select the external drive in Startup Manager. (Didn't work either: Startup Manager opened fine, but only showed my internal drive volume. I tried clicking the 'rescan' button, but it couldn't find my external drive.)
3. SELECTING THE EXTERNAL DRIVE under Startup Disk in System Preferences. Note that the external drive volume *did show up* there. So under some conditions at least, the external volume is identified as a bootable volume. (This didn't work either, though: When I shut down the computer and booted up with the external drive connected, it still booted up from the internal drive.)
POSSIBLE EXPLANATION?
My external drive is partitioned into three partitions of different formats:
1. "Mac OS X Extended (Journaled)"
2. "Mac OS X Extended (Journaled)"
3. "MS-DOS File System (FAT32)"
The bootable volume is the first partition with the os x format.
Could my problem be caused by this partitioning of my external drive?
Either way, what to do?? I hope some of you savvy people out there can help me out.
Cheers,
Philip

Hi Philip,
My problem has been fixed, & I imagine it's the same for you...:
With the excellent help from Dave Nanian at shirtpocket.com - the developer of 'SuperDuper!' (thanks Dave - you rock!), the problem (as Michael suggested) is to do with the Partition Scheme of the drive.
If your drive was like my portable LaCie Porsche drive, it was FAT32-formatted for PC out of the box. This format has an underlying MBR (master boot record) partition-scheme. When re-partitioning a drive in 'Disk Utility', the original partition-scheme sticks, so if you simply re-partition the drive to Mac OS Extended, it will still have an MBR partition scheme... which Macs cannot boot from!
For a Power PC Mac to be able to boot from an external firewire drive, the drive MUST have an APM (Apple Partition Map) Partition Scheme underlying the Mac OS Extended partitions. To do this, click on the 'Options' button in 'Disk Utility' when on the 'Partition' page before partitioning. You will see the options:
GUID Partition Table (for Intel Macs... (n.b. Power PC's cannot boot from a GPT drive))
Apple Partition Map (to create a bootable drive for a Power PC Mac)
Master Boot Record (to create a bootable PC drive)
So.... to make your external drive bootable for your Powerbook G4, choose 'Apple Partition Map' in the 'Options' page prior to partitioning.
Special note about Intel Macs: Contrary to info supplied by Apple, an Intel Mac CAN boot from an APM-partitioned drive (this is why the OSX installer can be univerally bootable!), BUT, the problem is that the OSX installer will NOT let you install OSX-intel on an APM-partitioned drive....
You can, however, clone an Intel-Mac-OSX internal drive that has a GPT partition-scheme (using CCC or SuperDuper) to an external drive with APM, & the Intel Mac will still be able to boot from that clone...
The only real use for doing this, though, is if you want a multi-partitioned backup drive with separate bootable partitions for OSX-PPC & OSX-Intel machines. (Remember that a PPC machine cannot boot from a GTP-partion-scheme drive, hence the need to use APM in this instance seeing as the Partition Scheme applies to the entire drive (it can't be different for each partition.)
Good luck - let us know how you get on!

Mac Mini i7 (Mavericks) will not boot from the external drive

Mac Mini i7 (Mavericks) will not boot from the external drive with Disk Warroir 4.4. or Drive Genius or Lion.
Not even from the external Firewire hard drive with Mavericks

Does the external HD have a GUID partition table?
Is the external drive formatted Mac OS X Extended (journaled)?
Is this a 2011 or late 2012 Mac?
How was Mavericks installed on the external drive?
Who is the builder of the drive mechanism in the external drive?
Who is the builder of the external enclosure?
What type of interface does the external drive have USB2, USB3, Firewire 400, Firewire 800, thunderbolt?
Is the external enclosure directly connected to the mini?
Have youtried a different interface cable?

Is it possible to boot or Time Machine restore from an external Thunderbolt disk drive?

(There are several questions - search for "?".)
I purchased a Seagate Backup Plus for Mac Desktop Drive 3 TByte with default USB 3.0 interface, and also acquired the Seagate Thunderbolt Adapter for Backup Plus Desktop Drives and Thunderbolt cable.
I do a redundant backup to the Seagate Drive using both Carbon Copy Cloner (nightly) and Time Machine (hourly) using its Thunderbolt adapter. BTW: One never knows when Time Machine will choke - see discussion titled, "UPDATED: Serious Time Machine bug on Mountain Lion", which I had; Rest In Peace Pondini (James Lewis Pond).
Booting from the external Seagate Backup Plus via Thunderbolt inteface from System Preferences -> Startup Disk:
I select the Time Machine OS X, 10.8.5 Startup Disk (Thunderbolt attached drive), click Restart, confirm my choice, the computer reboots, however, it reboots from the internal Macintosh HD OS X, 10.8.5, NOT the selected external Thunderbolt drive. The SSD drive was used as the Startup Drive, not the selected external Time Machine volume as indicated by the display free disk space command (df(1)) and seeing that the Macintosh HD OS X, 10.8.5 volume is mounted as root. That is very deceptive in that both the internal and external drives will appear in the same manner from a GUI point of view! OS X doesn't even inform me that it did not boot off the selected volume. This is the first half of the problem, that is, Is it possible to boot from an external Thunderbolt disk drive? In my case, the answer is deceptively No. Can anybody else boot off a Thuderbolt attached disk drive? Note that if I remove the Thunderbolt adapter, and attach the drive via its USB 3.0 cable, the MBP boots off the external Seagate Backup Plus just fine, as is expected.
Booting from the external Seagate Backup Plus via Thunderbolt inteface from boot-time "Option - Select startup disk" method:
When I restart the MBP using the startup Option key to select the startup volume, the externally connected Seagate drive ONLY SHOWS UP if it is attached with the USB 3.0 cable, not when it is attached with via the Thunderbolt interface. Can anyone else boot off a Thunderbolt drive with the startup Option key sequence? At least the MBP doesn't deceive me in this case - I know right away that the external Thunderbolt drive is not an option when connected as such.
Time Machine restore from the external Seagate Backup plus via Thunderbolt interface from the "command-R - Recovery Parition" method:
After booting from the recovery partition, I attempt to perform a Time Machine restore from the Thunderbolt connected Seagate Backup drive. When Time Machine attempts to present me with a viable backup Time Machine volume, the external Thunderbolt drive is never offered as an option. So I switch the Time Machine volume to use its USB 3.0 interface, and then Time Machine displays that drive as an option, and the MBP proceeds with the restoration as expected. The interesting thing to note is that while booted in the recovery partition via the Thuderbolt cable, the MBP Disk Utility may be selected, and the Thunderbolt attached drive may be operated on just fine. Can anybody else restore their MBP using Time Machine and the Recovery Partition via the Thunderbolt interface?
This is also a big problem for me in that I am forced to restore my MBP via Carbon Copy Cloner using the USB 3.0 interface, because I cannot even boot off that volume's Thunderbolt interface. Of course, the option may be that I could use yet another eternal USB 3.0 drive, boot from it, and then use Carbon Copy Cloner to restore the Macintosh HD via the aforementioned drive connected by a Thunderbolt cable, but that is less than ideal and not elegant, so I'm not going there.
Another side issue is that the commercially available program, TechTool Pro 7's eDrive, which I installed on the Time Machine volume, will not boot off that eDrive as advertised, but I won't got through those steps here, because that would be beyond the scope of this issue, however, I must say, It does not work either when the Time Machine volume is connected via the Thunderbolt interface, but works just fine when connected via the USB 3.0 interface.

If this helps anybody else make a decision about whether to consider Apple because of Apple's superior customer service:
Apple sells this entire line of drives right in their store, from 1TB to 4TB. I spent 1 and 1/2 hours, yesterday, confirming that the 3TB model IS NOT 100% Thunderbolt compliant. A MBP cannot boot, nor can it Time Machine restore from this drive, though EVERYTHING about the drive is normal.
Apple's South Coast Plaza store management had at least two responses to me personally about how to proceed:
1. Buy a different drive from another drive manufacturer, and to attempt to return the drive to COSTCO. A lead genius suggested going with GTech drives, for instance.
2. Wait for Seagate to fix their problem.
I told Apple management in the store that the drive is advertised as Mac Compatible (see picture) and that it is advertised as being a Thunderbolt drive (see picture). I pressed management that my purchasing decsion to get the best possible MBP Retina was based on the availablity of Inexpensive Devises (raID), and that not having this complete compatibility is a show-stopper for my needs, and that I wanted a refund. Their response? They needed to talk with "Merchendising" to see if they are on or off the hook for these kind of 3rd party assertions, and would get back to me.
I am not holding my breath.
Note: I do not hold this against the Geniuses that helped me, nor against the management I've dealt with, nor the upper level engineers that I've corresponded with through Apple Care - their problem solving skills were helpful - although I could have arrived at similar conclusions given enough $$$. (For instance, try a Lacie TB drive and see if that works - we did, and it did not work. Or, we have a different TB cable and a different TB adapter, let's try those - we did, and it did not work.) I blame myself for not doing enough homework before going with Apple's solutions.

Portege 244OCT - Is it possible to boot from a external CD-ROOM

Hi,
I've just got an old Toshiba Portege 344OCT laptop with an HD of 6 GB and with an intel Pentium III processor 500 MHz and 128 MB RAM. At the moment i have it under Windows XP Home Edition. I would like to revert it to Windows 98SE but the computer does not have an floppy drive or an internal cdrom. It does have an usb port, though. I am trying to boot the windows 98 cd from an external usb cdrom drive (EZ-DUB) but it doesn't work. I don't seem to find an option to boot it from an USB device either. My bios is from 27 June 2001.
Is there something that I can do in order to manage to boot my computer from my EZ-BUB? and how could I update my bios to the v1.6 without the floppy drive?
Thanks,
grdoming

Hello
Im not sure but I think an external FDD should work but I doubt that the external CD drive will work.
What you can do? In your case I would copy the win98 folder on the HDD. Therefore remove the HDD and connect it to an other notebook or PC as external HDD. Format it with FAT32 and copy the win98 folder from the CD on it.
Put the HDD back in the notebook and start the installation if you boot from an external FDD and a Windows 98 boot disk.

Problem Booting from an External Hardrive

Hi All,
I have a problem trying to boot from an external firewire hardrive. I have a iBook G4 running 10.4.8. and I'm trying to boot from an external firewire hardrive running 10.3.9. It will not boot. I get a grey screen with the international "No" sign (the circle with a diagonal line through it). But yet, I can take that same external firewire hardrive and hook it up to my iMac G4 running 10.4.8., and it boots up with no problem. Any help would be greatly appreciated. Thanks.
iBook G4 1.33 1.25GB RAM  iMac G4 1.25 2GB  iMac G4 800 1GB  iMac G3 600 1GB Mac OS X (10.4.8)

Here's an update. I think I figured it out. In the "get info" box of the external HDD, there is a checkbox at the bottom that reads, "Ignore ownership on this volume" and it was checked. So, I unchecked it, and rebooted, and now it boots up correctly. I'm not exactly sure what that checkbox means, but it's working now. Thanks to everyone for your input.

Booting from an external optical drive (Liteon ETAU108-01 or other)

Dear Apple community,
I´m considering buying the external DVD writer "Liteon ETAU108-01" as a replacement for my broken MacBook Pro (2 Duo) super drive.
Does anybody know, if it is possible to boot from this specific USB drive (eg. using DVDs with MacOS or DiskWarrior)? Or can I generally boot from any external optical DVD drive?
I´m also happy for recommendation of alternative DVD drives which would allow booting my Mac in an emergency.
Thank you very much,
Felix

will it recognize the external drive as the primary boot drive?
do I press C or option?
Will any external optical drive work?
Thank you very much!

Elitebook 8440p - recovery disc creation & booting from an external drive

I have a brand new Elitebook 8440p & I have a couple of issues that I cannot seem to resolve.
1. I expected to get some sort of system install, or recovery or repair discs - or the ability to create such disks with this laptop. Nothing came with it, and I cannot find any place to create some sort of system recovery disks, nor is there anything listed for this laptop on the HP site to acquire them from HP. I am not comfortable having no way to recover this computer should a hard disk go south. Any ideas how to create or get an op system disk or recovery discs or something?
2. I have an encrypted company/business hard disc inside the laptop for work. I also have the original hard disk that came with the computer in an external eSata/USB case. I have configured and installed software on the external drive to include my personal software and programs, leaving the company hard disc inside the laptop for business use only. However, I cannot make this laptop boot from the external drive if the company drive is inside the laptop. I have read and tried everything, but if a drive is inside the laptop, it will not boot from the external eSata/USB drive. If I simply remove the laptop hard drive, it boots perfectly from the external drive via eSata and works fine. How do I manage to get this laptop to boot from my external drive without having to remove the internal hard drive?
Any help or ideas someone can offer are greatly appreciated. Thanks very much.

Hi, Rich:
If you live in the USA or Canada, you can get a set of restore disks from HP for $10. I am surprised you didn't get a set but maybe they only come with the business desktops.
Here is how you order them:
1. Write down the part number and serial # on bottom of the computer on the white tag. The model # is an HP-Compaq 8440p, but the part number will be found on that white tag below the serial #.
2. Call HP at 1-800-952-7689, option 1 (ordering restore disks is part of the list in the option).
3. Provide the info asked by the rep that answers the phone. Some just ask for the serial #, some want both, or they will just want the serial number and type of computer (8440p).
4. Have a Master Card or Visa ready for purchasing. They don't take Discover. You will be charged $10.00.
You will receive the disks by First Class Mail or you can pay an additional $10.00 for FedEx shipping.
Sorry, I can't answer your second question. I assume you have already tried hitting the F9 key at the HP splash screen to select the device to boot from?
