Booting and shutting down

**PhilStubbs** · 08-20-2012, 09:39 PM

so, after having 15-ish browser tabs open looking for FAQ's i decided to just ask my question. the FAQ could really use some help. just sayin

how is booting and shutting down being handled in a car setup? i am considering a car pc for my truck, but dont want to have to wait for it to boot to have music and then shut it down every time i turn the truck off. i considered SSD drives for the quick booting, but that would still be far from a standard head unit startup time.

i have a 90 silverado. there is no room at all in the dash for even a single din head unit. my ideal end result is mounting a headunit or pc under the seat and having a small touch screen mounted above the climate controls to control everything. i would like to play music from a thumb drive for sure and a HD if i go pc route. if there is something out there that is more like a standard car stereo im fine with that, but in all of my research it looks like i will have to use a pc. every touch screen head unit i can find has the screen permanently attached to the unit and not remote mounted.

Have you had a look at this thread in the FAQ Emporium?

http://www.mp3car.com/the-faq-empori...-the-faqs.html

Not sure if there is an FAQ on the software side of startup/shutdown but heres a snap shot

assuming a windows OS

Options

Cold boot
Hibernate
Standby

and for Win7 and Vista(

) users Hybrid sleep/Standby/Hibernate

Using the above as search terms should give some info, everyone has an opinion on which is best, but a lot will depend on your hardware and peripherals you have attached.

I'll look into that. I could live with an automated setup that would wake the pc and start playing music where it left off within 30-45 second and then sleep the pc when I turn the key off.

I would probably use windows 7, but xp and Linux are also in the running. It seems that after all these years of carputers someone would have made a version of Linux just for this purpose.

LinuxICE was an attempt at that.

**PhilStubbs** · 08-21-2012, 11:22 AM

You say "was" an attempt. Does that mean its a dead project? Never very good? Reading about it sounds great unless I'm missing something.

**Enforcer** · 08-21-2012, 12:16 PM

It's not being developed anymore

its so unfortunate that linuxice never took off. I would have very much been happy with that instead of windows. Would have given my car that extra push into the crazy zone lol.

i am using a laptop with hybrid sleep and couldnt be happier. No more resume from hybernate screen. Just start the car and within 3 or 4 seconds the music is playing. Another few seconds and the gps antenna has connected and the OBD2 connection is restored.

For less time to wait for it to wake up mine was hooked up to the remote of the doors/alarm and it would switch of when a door was open. The m4 has a 1 minute delay so when i have the key in the ignition en switched it on the cpc would stay on. Switch of the car and it would suspend to disk in 10 sec.
boot-up time was 27 sec and walking to the car an getting in about 25 sec.
I used a bistable-relay and a normal relay to make it work.

Hmmm, what OS is on the laptop? If I could run it on one of those tiny carpc's that sounds great. Although, gps and obd2 aren't concerns of mine. I might want gps one day, but music is my main concern.

Is there a power supply out there that can stay connected to a constant 12v source and have another wire wake it up and make it sleep (for lack of better terms) with a keyed 12v source?
