AIR-LAP1142 Booting to Rommon

I have a customer that has an air-lap1142. He says that it boot to Rommon, and he has to issue the boot command to get it to boot. What is the rommon command to have the ap boot to the image automatically?

Here is a support document with instructions that will help you recover the AP:

My macbook air wont boot up. Just beeps every 5 seconds and a white light flashes on front of keyboard

My macbook air wont boot up. Just beeps every 5 seconds and a white light flashes on front of keyboard

That normally indicates an issue with system memory. The startup sequence can't complete the boot due to a memory issue. Take it in for service.

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed 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.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

BOOT ON ROMMON

My router 3745 boot on ROMMON mode could you help ?
Many thinks

Hi Friend,
Can you check if this router has some image in flash with a command "dir flash"?
Then try manually boot command to see if it boots up.
rommon>boot
If it boots then check the "sh version" and confirm if config register value is set to 0x2102 and also verify the boot statement.

My macbook air wont boot up

I get the grey screen with the spinning timmer animation.

See if you can boot into safe mode, if not youll need to reinstall your OS, how old is your AIR? Yours might have come with a boot OS memstick, of if running Mountain Lion you can erase and reinstall via net connection.
Mac OS X: Starting up in Safe Mode
Learn how to start up in Safe Mode.
To start up into Safe Mode (to Safe Boot), do this:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup in Mac OS X v10.4 through Mac OS X v10.6.8, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically. During startup in Mac OS X v10.2 through v10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
To leave Safe Mode, restart the computer normally, without holding any keys during startup.

My macbook air wont boot up past the loading screen. UPDATE

My 2008 macbook air will turn on, and then go to the apple screen with the loading wheel, but after a few minutes of loading it just shuts down...
Here is an update of the problem after i messed around with it for a bit.
I start up the macbook while holding Command+s
Then it brings up the prompt.
I then type: /sbin/fsck -fy
It then outputs a message saying:
disk0s2: I/0 error.
Invalid sibling link
(4, 42746)
**The volume macintosh HD could not be repaired.
/dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8
After that, i type in: /sbin/mount -uw /
Then I type: exit
It runs the logout scripts and then immedietly boots up fine, like the computer has no problem.
It works fine like this, but i dont want to have to do those steps every time I want to use my macbook...
Any help on how to fix this?

I have a similar problem. Not sure you're on here (since the post is really old) but did you manage to work it out? How?
My thread:
https://discussions.apple.com/message/19007548#19007548
My Imac froze earlier today as I was dragging an image from safari into indesig and when it froze the weirdest pattern overlaid the screen. It looked just like the opacity pattern from photoshop with grey and white squares. I turned the computer off using the power button and unplugged everything.
Now when I try to start it these weird lines appear on my start up screen (see link)...
http://meijerladdaruppgrejer.wordpress.com/2012/07/24/oops/
as you can see the apple and the wheel appears as normal...
... then it moves to a normal looking white screen (perhaps a bit greener than usual) and around 30 seconds later freezes at the blue screen.
I've tried the cmd + alt + p + r several times but it won't help.
If i press alt during start up I can see and choose my hard drive but just end up at the blue screen again.
Can I try starting it up in safe mode or something?

Macbook Air 2012 booting slow (45-50 seconds)

Hi guys, my Macbook Air 2012 is booting really slowly. It's on Mavericks.
I have tried resetting PRAM/SVRAM, didn't help.
I have tried manually selecting the startup disk, didn't help.
I have tried repairing disk permissions, didn't help.
I have no idea what else to try...
Any help at all would be greatly appreciated.

Macbook Air Freeze Booting White Screen Spinning Rainbow Circle - HELP

Hi All,
To begin with this happened to a macbook air which has not been turn on for around a year. This is Macbook Air Mid 2011 version.
After plugging in to charger and power on, the boot up after the grey apple logo stuck on the white screen with spinning rainbow circle, like below:
I Did Option + Power on , and the result is like below screen:
After enabling the Wifi connection and choosing the Recovery HD, resulted back to white screen with spinning rainbow circle.
I wonder why there is no Macintosh HD partition like many have mentioned in other threads??
I Did another type of Booting and after enabling the Wifi connection, still resulted Apple Support 5005F like screen below:
I tried googling to find what is 5005F and how to fix that, but can not find anything related to 5005F.
Please kindly help me to Fix and bring back this Macbook Air back online and working.
Thank you Thank you Thank you...

If you have booted into single user mode and ran "FSCK", and it will not repair, then it sounds like your hard drive is gone.
You will likely need to replace the hard drive.

The Air cannot boot from external dvd-drive

Hi!
I am using my rev.2 air, 1.86 Mhz prosessor, 120 GB HDD, leopard 10.5.7 with a Samsung writemaster external dvd-writer, but I am having problems booting from it.
When I try to boot (pressing option) I can choose the disc and the applesymbol will appear, but the spinning wheel below does not, and the screen just stay the same until I cut the power.
I have tried to boot both the original OS X-disc and Windows 7 (both through boot camp and normal restart) with the same result.
Any help will be...well, helpfull

Not sure if this will help - but whenever I need to boot from an install disc on my MBA - i turn on the MBA and hold the 'c' key until i hear it loading the disc. that's how I boot off of optical discs... worth a try?

4948 switch keeps booting in rommon

Went to do a password recovery on the switch so i put it in rommon. changed the register to x42 and it still booted with the password and config. After that i went back to rommon and set it to ignore startup config.. After that i booted it into a config without a password... Now no mater what i do the switch goes straight to rommon and i have to issue the boot command to get the ios to boot... Any ideas on how i can fix this?

I found the issue. Somehow i deleted the ios and all boot configs.

2610 suddenly boots into ROMMON

A week ago or so I tried xferring a new IOS image unto my 2610; but it was too big for the flash memory I had installed. I got an error message that it had (naturally) aborted the TFTP transfer; except I thought that meant it would have left the old IOS image intact. I now believe it didn't do that, because today I booted up the 2610 and I got this:

==================
"tftp" isn't one of the available commands in ROMMON mode so I wonder how I can go about getting the old IOS image in place back there.

Here's a freebie that should help.

When you download the IOS image, it will show you what the MD5 hash is for the image, just make sure it matches what you have on your PC. Attached is a screenshot of what you need to look for.
For future reference, you can check the image from IOS with the following-
RTR# verify /md5 [file to be verified]

Macbook air not booting as fast?

i have the 2010 11 inch macbook air. with their SSD's theyre known to boot up super fast (roughly 15-30 seconds), however, mine takes up atleast a minute. is there something i can do to restore the boot up times?

do u have loads and loads of files/programs installed. if you do, try and uninstall all of the ones you dont or bareley use. also, when you shut your computer down, make sure you untick the box to say 're open all programs at startup.'
if you want to see what programs you have open, simply hold down command, option(alt) and esc at the same time, and close all the open programs you have open which you arent using.
hope this helps

Macbook Air not booting up

I have '11 inch and 64gb Macbook Air, Mid 2011. I am using Mountain Lion 10.8.2. I was using Magican and find duplicates. I found some, and I erased. Then my computer started to turn off. I turned it back on, and there was only an Apple Sign and a mouse. How do I solve this problem without my files disappears?

You may well have erased files essential for the system.
Hopefully you have a backup to have your files safe?
Or you can boot from an external disk to then be able to access the files on the internal SSD?
In any case, you will likely need to re-install the OS X. Then leave your fingers from files you don't know. Best stay away completely from any of these silly "cleaners".
