Sun V100 should boot from disk

I read a lot of pages and manuel, but I do not find the right comand sequence in lom to set the boot mode from "net" to "disk".
My system always does a "boot net".
regards/TX
TAB

It isn't a LOM setting you need to review, but your settings in OBP.
If you do not already have them, get the V100 documentation from Docs.Sun.Com
[http://docs.sun.com/app/docs/prod/v100.srvr?l=en&a=view]
Connect to your system and get to its OK prompt. Review its current setting for boot-device (it should be at the default of `+disk net+` which means it will try to boot from the drive but when that fails it will boot from the network -- standard behaviour).
If your system is failing to boot from the disk drive, you either have a missing or failed disk or you have a corrupt bootblock on that drive, or you have simply not installed a bootable OS to that disk.
The documentation has everything you need for that V100.

Wich Sun machines can boot from SATA disk?

Hi,
I would like to know which (newer and older) Sun machines can boot from SATA disks.
I think this is a feature of the OBP - so the question is:
Are there any updated OBPs for older Sun machines to boot from SATA disks?
TIA
Bernd

Hi,
I am aware the limit with earlier openboot revisions that limit ATA drive size to +130GB>>( search the forum for previous threads on this topic ), I recommend using only
supported drives in Sun SPARC systems. What kind of project are you working on? That's my private test environment. Due to my limited budget I use only older machines there (for example, U10, U30, etc). I was thinking about buying a used V120 or something like that to replace my existing fileserver.
A V120 with two internal 500 GB harddisks would be perfect for that .
Looks like I've to wait until used T1000 are available to a reasonable price.

Bernd

Which keyboard layout you were using? German, French ... I suppose your layout is reset to the default: US and you are unable to find the "?" or "/" ...
Please have a look into the keyboard viewer, to see how the layout of your keyboard is actually.

Folder with question mark + wont boot from disk

Hi
I am trying to reinstall a powermac g5 from the disk, using a old hard drive that works.. (formatted in NTFS) (hoping that when selected to boot from disk, mac will then erase and reformat it)this image is presented when i hold down the option key and the disk ejects this other image is presented when i hold down C (folder with question mark blinking) and the disk ejects... also presented if i boot normally.... Could some help be offered please??????
Powermac G5
Thank you in advance

Yes, you must Format it HFS+ first...
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

Boot Issue BIOS won't boot from Disk

Ok, heres my issue. First I was having issue installing Win2k and found I had to disconnect my USB ZIP drive to boot (BIOS Option was disabled)(This is just a note). After installing WIN2k on a WD300BB I was having no issues until I removed my Win2k CDROM disk. At that point the bois (seeing the drive) would not boot (Insert a bootable disk error). To get around this issue I created a bootable nt floppy disk to boot the hard drive.
I also attempted to do a fdisk /mbr with no help. If i put the win2k cdrom into the cdrom drive and have one option to boot from CDROM it will boot from disk. I do NOT hit a key to boot from cdrom. I also cut wire 1 & 2 from IDE cable.
Any other ideas?
Thanks

Thanks for the reply, the IDE cable is cut and there are no jumpers on the drive. This is a bios issue. If I boot from floppy to Win2k, this system works greate. But it will not boot off the hard drive with out assistance.

HP 3500 MicroTower doesn't boot from disk!

We are facing a very strange issue with HP 3500 , the machine can't boot from disk ! only way to get it to boot is to pxe boot it.
Whenever it can't find a Pxe server to boot from it failed to boot from disk with an error that "No boot disk detected ... "
Disks are detected correctly in the setup/bios and quick smart check tests are passing successfully.
I have tried to disable the network boot but this didn't help as well, it indeed skipped the Pxe boot step but it still fails to boot from disk with the same error.
The OS installed on the machine is Ubunutu 12.04
Note:
We installed extra 2 disks to this machine and 2 extra network cards as well , not sure if this is related but I thought it worth mentioning it.

Problem with kernel panic message - Cannot boot from disk or usb

Hi Everyone,
I was wondering if someone could help me with a problem I've been trying to tackle for the last few days. I have a 24" iMac 2.33 Ghz Dual Core, with 2 gigs of RAM. A couple of days ago my computer crashed, and when I tried to boot up again I got the infamous grey screen kernel panic message ("You need to restart your computer..."). What's worse is that I get the same message when I try booting from my external drive and the installation disk itself.
I've basically planned on formatting since it's been a while anyway, but since I can't boot from my external drive or the installation disk that came with my computer these are not options at the moment. I can only get into the computer via safe mode. I've used disk utility to verify the disk, and it comes up with no errors. Anyways, I'd really appreciate if anyone had any advice on this. I've scoured the internet for advice about kernel panic messages, and they all suggest booting from disk or external drive etc., which is not a possibility for me right now.
Thanks

If you get a panic when trying to boot from the installation disc, and the disc is not scratched or dirty, then you have a hardware fault.
Make a "Genius" appointment at an Apple Store to have the machine tested.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Losing User Accounts on many machines. Cannot boot from Disk. Help!

As many of you know there is a bug going around where the OS “forgets” what user accounts are on the machine. The only user at login is “Other”. This has happened on 10.6.5 and 10.6.6. In the past I have been able to fix this issue by booting from the Snow Leopard disk, change the root password, login using root and re-add the user accounts back under system pref’s. The issue I’m currently having is that two Mac Pros will not boot from disk, external HD, or into single user mode. None of the key commands work at boot up.
The computers do not chime at boot and the apple logo shows up very quickly. I’ve tried resetting PRAM and the logic board. I now have two BRICKED machines and cannot afford to have any more go down.
Any help on this issue would be greatly appreciated!
Thanks

I just had a very similar problem this morning on my iMac. Plain white screen on boot-up. No Apple logo. No booting from my SuperDuper clone, no booting from the DVD, no booting into Startup Manager by holding down the option key, no booting even into Apple Hardware Test. I was getting ready to take it in for service.
What finally fixed it was resetting PRAM three times. Hold down command, option, P, and R, and keep them down until you hear the third startup chime. That's what finally breathed life back into my iMac.

Sun v40z wont boot from external DVD/RW drive

Hello folks, I am banging my head on the wall with a Sun v40z that will not boot from an external dvd drive. I want to install Win2k3 Server on it. Any ideas.

The v40z is an x86 platform,and thus has a BIOS controlling the boot order and boot devices. You'll have to attach a VGA display and keyboard, power on the system, then hit F2 or F10 to enter Setup (it should say what magic key it is at startup time, just after the SUN logo splash screen comes up).
Enter the BIOS, and go to the menu for boot devices, making sure you select CD-ROM as a boot device before your regular boot disks or network boot devices. Then Save and Exit, restart the system, and it should see and use the CD for the boot device.
A caveat is that some early revisions of the BIOS's, especially ones on early x86 platforms like the v40z, will not recognize an external device as a boot device. You may have to download the latest BIOS, install it (uses a floppy, IIRC!), set the correct BIOS options again (they get wiped out when the BIOS is reinstalled), and then try the external CD boot again.
If this fails, you would be forced to install and internal CD device. This is not difficult, but is obviously more hassle than an external device.
Good luck!

G5 will not boot from disk

I cant get my G5 to boot from a dvd....
It will boot off of my hardware diag dvd ,but not off of any 3 of my install disk
Any ideas?
I tried a few commands in Open Fimware prompt :
reset-nvram press Return on keyboard
set-defaults press Return
reset-all press Return
and when i tried the commands the first time, my computer restarted and was able to boot from the os dvd...( after i got it working, i turned it off and tried again, just to see if i fixed it)( i didnt fix it).but now when i type the commands, my computer hangs up on the last command.
Do you know of any other commands i can try, to get my system to boot from a os dvd?
Thanks for your help

It means something is going wrong before the startup process gets to the stage where it can accept the startup key command input. There are various checks that happen (called POST - pre operating startup test - if I recall correctly). The firmware checks basic things like is there a processor available, how much RAM is connected, is a drive connected…
I think all the early stages are handled by the Boot ROM & NVRAM, these are generally not 'user fixable'. It indicates something is badly wrong. It could be failures in the main logic board or CPU(s) or the power management unit or possibly a dead battery (the small internal 'clock' battery is cheap & easy to replace - worth a try -> search this apple support for 'G5 YOUR MODEL & replace battery')…
Of course it could be something simple like a failed keyboard or usb hub, so try removing everything and just use the Apple keyboard & mouse and one display directly connected to the G5. You should also look for other signs such as beeps or flashes of the power button on startup, remove the outer metal door & look along the RAM slots for any lights when it gets powered on. The support site has info on what they mean.
It couldn't really hurt to try removing and replacing user-serviceable parts such as the graphics card, RAM, HD. Sometimes connections may need reseating. You will also want to remove any other PCI cards that are installed. Again the support site has instructions for all of this, sorry I would link to them for you, but I can't make sense of the model description in your posts.
An Apple service center may diagnose this for you, but unless you have Applecare they will charge you for it.

Formatted Mac Os X accidently. Now wont boot from disk or hard disk. Help!

Hello,
Last weekend I managed to stupidly and accidently wipe my mac os x part of the HD when it was meant to be for the partition I had freshly made for boot camp. Since the mac os x part of the HDD was formatted as NTFS, I now cannot boot to that and have been trying to get on to disk utility to sort this mess out... by booting to disk... problem is... it wont.
Long story short.
After insertng the Mac Os X Tiger install disk and holding C it does not force boot the disk and all I see is a grey folder icon with a question mark which flashes several then vanishes... I've tried inserting the disk and holding the Option key, and C... and also tried tapping both option keys fast to no avail... the cursor appears however when I do both and it then freezes and the screen stays white.
Tried phoning Apple tech UK to discover i'm out of applecare cover and it'll cost me £35 to get incident cover for this incident. She then said at the end,.... you just need to get to disk utility and sort it from ther... problem is.... I cant get there.
Apologies for the mini-rant... I've just tried every solution and I'm still at square1.
Thanks in advance..

+Any other suggestions?+
You didn't mention whether or not it still sounds the start-up chime when you try to boot.
Also, will it boot to the Apple Hardware Test (located on one of the grey-labeled original system discs) - hold down the d key instead of c key. Has it ever run the AHT prior to this problem?
Were you successful at performing a PRAM reset? Only this will cure the iMac of its propensity to search for the old startup disk. Had you ever done one prior to this problem? If you can do that and then immediately switch to holding the c or d key, it must force a boot. Since all you need is for it to boot, you should have no external device connected to your iMac.

Problems Booting From Disk - Wireless Keyboard

I've been having problems with my 20" PPC iMac running 10.4.11 - thread here: https://discussions.apple.com/thread/3322473 - and have been trying to run my copy of Diskwarrior 4.1.1, as it's fixed some previous issues I've had.
I've tried dozens of times to boot from the Diskwarrior disk, but, whatever I do, the disk ejects and OS X launches as normal.
I understand that keys C and Option on the Apple wireless keyboard should be able to be "read" by the maching on start up, but I can't get it to work. The disk in the drive spins up as expected but is always ejected, and OS X is launched. I've tried both shutting down and restarting manually and restart from the Apple menu.
Exactly when should the Option or C key be depressed (eg. on the start up chime, as soon as it's switched on, before it shuts down), and for how long?

Try holding down the option key then power on. This brings up the startup manager. Click on your cd. Click on right arrow key. At least you will know if your keyboard is working.
I read your other post. I do not have an idea what is going on. Suggest you run the hardware test. Many machines came with hardware tests on a cd/dvd.
You may want to run these "standard" fixes if the problem persists.
Check the amount of free space on your harddrive. You should have a several gigs free.
You should run disk utility
a) verify the disk
b) update your permissions.
Try a safe boot.
Shutdown your machine. Hold down the shift key. Poweron. Wait awhile Wait awhile while you harddrive is being checked.

Can i create a disk image of my Imac 27 triple boot from disk utility: lion 10.8.3, win 7 and snow 10.6.8

I have created a well working triple boot system on my Imac 27, I7, 16GB, 3.4.Triple boot: Lion 10.8.3, Snow leopard 10.6.8 and windows 7.
They all work great. I would like to find the simplest way to make a image or a backup of the entire system.
I am thinking of creating a new image from disk utility image option.This from the main 2 To hitachi disk. The image option at the top should create a global image of the entire triple boot. I am not shure if this is possible. The differential/incremental option is not necesary. I can deal with that.
But, In case the disk utility option will not work, which software would aloud diferential/incremental backup for each partition
A software solution that would babkup all my partitions.
A single all in one image would be great but is that possible?
Any suggestion: please d'ont talk about vm solution or other subject like that. I am looking for a backup solution for my tripleboot...
Thanks
