Hi all,

I just timed the (cold) boot procedure with my A1/G4@800/OS4

I goes something like this:

0 sec: Switching it on :)
7 sec: First text appears
13 sec: 5 sec countdown:
18 sec: Uboot boot delay (2 sec)
20 sec: loading kickstart
26 sec: launching kickstart:
36 sec: Screen goes black
56 sec: WB pops up
59 sec: Done

Now I was wondering if this is quite normal.

And if I (we) can shorten the boot time by reducing the 5 sec countdown
at the begining (I know how to cut down the U-Boot delay, already did this)
I Guess the 'loading kickstart' time will be shortened when the IDE UDMA is
in place :)

Is OS4 pre still sending information to the serial port for debugging ?
And is this partly the reason why it takes 30 sec after 'launching kickstart'
till WB pops up, and why it takes a few seconds for the system to actually
reboot after pressing CTR/WIN/WIN ?

It is still ALOT faster then my Win box, but thats obvious :)

Cheers,

Martin

What devices do you have on your IDE chains? If you have missing devices, there is a 20-second timeout each time it comes to a "hole".

If this is slowing your boot time, you can avoid it by connecting something (an old drive, for instance) to that position.

Also, if you have Ethernet connected to a DHCP server, it takes several seconds to negotiate the DHCP connection. You can do this in parallel by editing your Startup-Sequence to say "C:Run >NIL: AddNetInterface (etc)".

The boot time is not affected much by disk access speed. When you watch the blinkenleits, you can see that it isn't spending much time on disk accesses. And unless you have the debug kernel version enabled in U-Boot, the small amount of serial output won't slow it much either.

On my A1 with a large User-Startup, USB, Ethernet and the works, I consistently do a cold boot in 47 sec and a warm reboot in 16 sec (no DHCP).

Hi,

I added the 'run >nil' stuff to my startup sequence, and it boots 10 secs faster now ! :)

I have on IDE 1 a Hardrive, on IDE 2 nothing, on IDE 3 my CDRW, and on IDE 4 nothing.
Still it doesnt take 20 secs to go through the initializing of the IDE ports, it takes 18 secs till the 5 sec boot delay. Or did I misunderstand you ?

Thanks :)

Martin

@tonyw

The debug takes a little while though. Is there any way to set the serial speed in U-Boot to f.ex. 115200 instead of the default 9600? That would speed it up 12 times!

I coldboot in about 43 seconds.
Warmboot ~12 seconds.

Is it possible to remap the keys for a warm reboot? (ie, ctrl-win-win). I ask because I only have one windows key on my keyboard.

Yes, it is already taken care of, as well as the ability to remap the HELP key (Scroll Lock) for those with KVMs.

My current boot time is 36 seconds from a cold restart. I'm not going to break down the timings, but from a Ctrl-Alt-Alt to the User-Startup and WBStartup finishing, including the Workbench background loading and changing TWICE totals 36 seconds.

It seems your total UBoot delay is 7 seconds, mine is only 3. I only have one delay, not two. How do you get two countdowns?

@Deniil715

You can set the baud rate with the U-Boot variable "baudrate", eg:

setenv baudrate 115200
saveenv

That will change your A1's baud rate to 115200. The serial prefs are not yet used (?)

@lizardrock

setenv bootdelay 0
saveenv

will remove the first countdown. Make sure you have the option to drop into the U-Boot prompt from the second countdown (space, escape, last option) before you change the above, otherwise you will run into problems if you need the prompt.

Do you know if there is a way to make Uboot to stop for each page of info? Printenv for example scrolls of the top of my screen too fast to be able to read everyting..

@Vidar

The only way I know to stop it, is to hit Ctrl-C as quickly as possible (ie. before it scrolls off the top of the screen) after hitting return. You have to repeat the command as many times as you need to to read the entire text.

It used to pause. I guess they have taken this out of 1.0.0 (I've not tried it).

Another option is to capture the output across a null modem cable. I don't know whether Ctrl-S or Scroll Lock will pause the display, they might be worth a try.

No, that doesn't is not responsability of a1ide.device but Uboot's routines, since OS4 is not (yet) there when loading the kickmodules. To shorten that time a tuneup of the VIA inside uboot would be required.
We might do that, in fact there are already plans for it , but it's low priority.

Bye.

@Bodie

Type this in uboot...

setenv kbddev_norwin yes
saveenv

and the 'menu' key will be used as r-amiga

@Severin

I hope all these environment variables will be explained in the final OS4 documentation Or is there some UBoot manual/tutorial online ?

@STRICQ & Severin

Thx for the tip.

Cheers

OK I did find it already U-Boot documentation is atleast here (Don't know if this is latest version)

http://www.denx.de/twiki/bin/view/DULG/UBoot

@all

Thanks, very usefull tips.
I will try the 'bootdelay 0' and the 'baudrate' stuff later today

I think short boot times are important, even a cold boot, so I will try to cut it down as much as I can !

Right now it already (cold) boots faster then my Amithlon box :)
And my A4000/3.9 (with al its reboots and patches running)

I'll let you know if the baudrate bit (hihi..) changes the boot time.

Cheers,

Martin

Hey guys !

Guess what....

I used 'setenv bootdelay 1' and it shaves 4 secs of my boot time !

Also 'setenv baudrate 115200' WORKS ! :)
It makes OS4 boot 7 seconds faster !!!

GREAT !
So I'm down to 38 seconds cold boot WB fully loaded including backdrop picture, amidock and WBstartup :)
(It was 59 seconds)

Thamks again.

Martin

ps, we must share this with every OS4 user out there :)

@lizardrock


Boot up times ?

Who cares .. Its way faster than my PC anyway..


Its the SHUTDOWN that impresses me !!
