Reach over the drivers side front tire in wheel well.  Reach around trim in upper wheel well to find a cable, running front to back, pull toward you and it should release the front hood.  Previous owner showed me this emergency release in case battery goes dead and I have recently had to use it myself on my 1998 Boxster.

    can't find this cable. is it hidden behind anything or behind the spring?

Inside the top of the driver's front wheel well, just aft of the spring coil mount, is a little rectangular corner in the black plastic shroud that lines the inside of the wheel well. Reach under this, and you will feel a "wire" about 1/8" in diameter. Too thick for an electrical wire (and not in a harness anyway).Now tug this cable gently out from behind the shroud and get a good grip on a loop of it. Now pull hard away from the headlight once, and prepare to hear the music of the alarm as the front hood pops open. Grab a 10mm wrench and take off one of the battery cables to silence this thing until you can get your key in the ignition and disarm the thing.
Disconnect the alarm horn, re-connect something with power to the battery leads, and unlock your car.

Toninlee is quite right but for the less technically minded. I could find the terminal to start with. On my 2007 boxster its red to the top RHS of all the fuses with a helpful sign showing an opening bonnett.

I just had the same issue on my 2001 Boxster. There is a simple solution. The ciggarette lighter won't accept any power so you can't use this. You need to buy a Sealey 12v Memory Saver Diagnostic Socket EOBD VS2072, around £30 on ebay. This fits into the EOBD port which is just under the dash on the passenger side, with the other end attached to a slave battery.(anything 12v, old car battery or jump pack.) This will instantly give you power to open the bonnet etc. Job done. This won't allow you to start the car, just enough to access the battery. The other benefit is it will save all the radio codes etc (as long as you keep it hooked up while you charge/ replace the min battery. ) Good Luck! Tim

By the drivers foot there should be a panel (RHS) which can be removed if necessary to get access to a type of terminal. U can attach a live feed (jump start lead from another car to this point ,)attach the negative to your door hinge and this should then provide enough power to get bonnet open (its like jump starting the bonnet release!!!) good luck

you could try to get two male connector charging cable.They sell it at the dealer or on ebay.
And charge the Porsche trough your cigarette lighter socket.For that you could use battery jumper as well.
Then you can open the trunk to get to the battery.

1998 porsche boxster, battery is dead on car, and

This is a common problem. Your alarm was on when the battery went dead. When the alarm activated, the hood/bonnet opening lever locks to prevent thieves from opening the hood in case the top is down. Some boxsters have a jumper post the pulls out near the fuse box. However, I do not think the 1997-1999s have this post.

Buy a male-to-male cigarette lighter adapter at the auto store. Connect between your car's cigarette lighter socket and the other car's cigarette lighter socket. Do not try to start the ignition or the any other electronics. You should not even need the key in the ignition. You should be able to pop the door locks with the remote and open the bonnet.

You may also need to recover your radio code: http://www.a2dvoices.com/realitycheck/porsche/

The car wont start. it blinks a lot of lights makes clicking

I had these problems on my 2005 911 when the battery died. Apparently when it goes IT GOES. I had no problem with the battery until this time and then suddenly it was dead.

I've heard since that this is common on Porsche 996 when the battery is dead and then is should also be the case with the 986 Boxter.

I removed the old battery and left the car without a battery for at least 30 minutes (while doing some other maintainance). Put a new battery in and no problems after that. On most cars if you disconnect the battery for like 15 minutes the maintainance computer resets its self and all warninglights should dissapear unless there is a real fault, then the appropriate light should come back on!

Good luck.
Slick.

Manually openning the trunk of a 2002 porsche boxster

It can only be done using the key fob. Othersise use button inside the car. If your battery is flat you need a donor battery wiring to a connection in the fuse box (positive) anf door lock(negative) but see your hand book.
