Improving booting time

[Durand]

Hi everybody

I am looking for a solution to improve booting time. It takes about 35
seconds for my embedded pc to boot but i need it to boot the fastest
possible (i have been told of a 5s boot !).
I would be very glad if anyone could give me tips to get my image booting
faster...
Do i have to create an msdos.sys ?
May i disable some components which are slowing XPe boot ?

Thanks for everything,

Caroline Durand

If there are components you don't need, you can remove them. This may or may
not speed up the boot time.

Have you looked into HORM? HORM provides the fastest possible boot time for
XPe.

Hi
Thanks for your answer, and your help !
Can you tell me more about HORM ? Is it a component which is to be added to
the image ? or something to install once the image is running ?
I have already removed all the components i don't need but it doesn't change
anything.

HORM is a combination of EWF and hibernation:

It is also covered in the XP Embedded Supplemental toolkit book:

sorry if I'm wrong, but why don't use the stand-by instead of the shutdown?

it will speed your boot.

Hi,

The idea seems to be a very good one, but i'm afraid it is not possible
cause my system is to be used in a car and will be electrically shut down
regularly...
Difficult case, isnt't it....

Thanks for your help

Caroline.

It is good to know the project. I know of someone else involved in a Car PC
project, and they are using HORM.

We went through a similar process and went with the Standby solution.
HORM still took around 20 seconds to read load RAM after boot,
depending on the speed of the local drive.

For power solution, we had a secondary battery that would power a
sleeping processor for 21 days. A processor in standby mode has
very little power requirements.

The resume from standby still was not instantaneous, it took
perhaps 5 to 10 seconds for the system to resume functionality,
short enough in our solution to be transparent from the user.

Regarding other methods to reduce boot times, run Bootvis
and use the results to determine where any bottleneck may be.
We found that an ethernet jack that wasn't being used was
adding a full 10 seconds to the both boot and standby resume
times. We simply disabled it in the device manager.

Also check your BIOS settings, you can shave some time
by disabling or fixing some of the settings.

Thank you Perry !
I will now study the way we can install and use a secondary battery for our
system. This can be THE solution ;-)
Was it linked to to the vehicule battery ?
I will have a look to HORM also, but if it still takes about 20 seconds...
Once the system will be achieved, i'll try bootvis.
Thanks again

Caroline
