Does someone heard/read that?

We need the same on OS4 [for the X1000] !

@diegocr

Moving to general computing forum.


Regarding 1 sec boot, well, impressive indeed, but, that is for embedded, and we would like OS4 to remain usable as desktop OS as well, no?

1 second is not enough to start up the HW of a personal home computer.

"The DMA agents can move many boot tasks between flash memory and the processor memory and can accomplish this task in the background without processor overhead. “These days, CPUs have a pretty large cache memory, so they are capable of doing all these things in parallel"

If they manage to get linux to boot in one second (after the HW is on), AOS4&MOS&AROS should aim to 100ms with the same tools.


(if x1000's CPU has 2Mb of L2 RAM (like PA6T), it would/could/can help a lot)

That reminds me of when I first started with computers, they all used to boot up in about 1 second, the operating system of the ZX Spectrum was ready in about 1 second, saying Quote:

Loading the applications from tape however, took a good deal longer

Have you looked into using OS4 for embedded applications?

Runs >NIL: stuff in parralel in boot?..

Only loads the modules that are needed?

uses RAM: disk instead of buffers?

Only loads teh startup routines to initialise the system then loads the main code (libraries?) as required?

THESE GUYS HAVE REDISCOVERED AMIGA?

And people have laughed at the outmoded and outdated ideas of AOS.. ok, for some situations it is.

Then again, Concorde is old, slow, obsolete and outdated.

Will be intresting if the ludicrous speed boot kernal can be combined with the setup for the bulk heavy processing requirements of modern (?) desktops, to let your AI unlock the car door as you blip the keyfob, then set off to your destination as youve asked for getting in the door.

Finally, after nearly 30 years, people are getting round to program computers as theyve been taught? Because of the limitations of market and management?

According to article:

These fast-boot developments are not necessarily limited to real-time or an embedded Linux; however, they can get a conventional Linux distribution to boot in 1 second, as well.

You compare something so trivial as RUN to launchd?

Quote:

Was always present in Linux.

No. There's nothing powerful about AmigaOS startup procedure. Startup-sequence and User-Startup does not give you so much flexibility as other solutions.

@opi

To be quite honest, the boot time in Ubuntu increased dramatically for me about one year ago.

And I actually think that with some sensible work here and there AmigaOS could be just as fast as Montavista.

Preload sensible stuff in a ramdisk (or better yet, preload a sensible starting point for a wake-up-from-disk in the bootloader, using DMA) and run through all the driver initialisation processes in parallell, then you'll be pretty close.

They did some experimental work with laucnhd IIRC. I have skipped few Ubuntu releases due lack of quality so I have no experience to compare.

Sure. There's no magic here. I just try to refute this "AmigaOS did it first, it's so awesome, damn copycats!" statements. You can speed up boot procedure of any OS.

I think I saw Amiga video on the youtube where A1200 booted in 2...3 seconds to a full desktop etc...

....trying to lrelocate the video now....
not this, but interesting anyway ... http://www.youtube.com/watch?v=2fWfqRd3E3E
not this, but does the trick as well http://www.youtube.com/watch?v=qIMQUVn7GWc
(that was 4 seconds)
not this, but kind of funny http://www.youtube.com/watch?v=sojf2-VNSWw
(again 4 seconds)
next...


I did not find the real thing.
It used SD/flash hard disk.

@KimmoK
My a1200 with a blizzard 68020/4meg accelerator boots 3.1 in less than 5 seconds as well using a regular IDE hard drive.

@diegocr

Is it not better to have a stable Os? so you dont have to resteart it ...

@eder

There is no OS that does not need restarting.

But, yes, stability is very very important.

Linux is pretty damn close though.. My linux box that i use as main computer did 250 days twice in a row. It has so far not crashed in the last 3 years even once, even though i use it heavily daily. The only time it was rebooted was due to swapping hard drives or power outages. I am currently at 83 days and i bet it will do a year if i dont have power outage before then.

@Tomas

Yes, Linux only requires rebooting when you need to change kernel really.
Though, Windows 2008 is the best windows this far what comes to stability, my W2k8 I use as desktop was booted 65 days ago, and that was due to a system update, so did that manually, w2k8 has never crashed, been using it almost a year now.

Yeah, you get the point! congrats

That's the idea, i think we can attract a lot more users to our world/community if we can announce the X1000 as booting in one-or-two seconds (imo), as one of its innumerable features, of course

@Tomas

I think it very much depends on what people do with their computers.

Also on my x86 machines linux crashes very rarely. But usually I just reboot rather than spend tens of minutes in trying to revive the windowing system. (I get 100% surely some lock up if I watch pårn for a while with Opera or Firefox.)

Anyway, almost on every device, it's safest to shutdown (savesettings and applications states) & restart rather than use suspend for a night to save energy.

So suberb fast boot & shutdown times can also be "green" marketing slogans. Kind of.

@fast booting

x1000 BIOS could/should have a feature where user can set the system to start with fixed peripherals (in 100ms) rather than wait & pulg&play&autoconfig. Then if autoconfig needs to be triggered, user can do it in BIOS settings or on the booting with some specified key press, or on the fly, after the desktop is loaded.

Remember that x1000 also has a CF card slot as a standard, so no HDD spinup waiting is required.


Mode---> Also... if xena can be set to run also in "standby mode" ... it could do some smart motion detecting and start up AOS when some criterias are met. Perhaps AOS would then manage to boot before a finger reach the power button >--- mode

@fast all

As a matter of fact... AOS4.x for x1000 could be shipped on a bootable CF card. No installation needed. Just stick the CF card in and flip the dang power switch and wait the 999ms for the desktop & screen to lit up. No stupid installation needed.
