Also, with any kind of device, throwing up a banner ASAP gives the
appearance that the device is useful before it actually is (this is used
by Microsoft to great effect - to make their multi-minute boot times
look like sub (but not by much) 1 minute boot times
However, given the field in which Mr. Belanger appears to work, he is
probably concerned with power-on to fully-functional time, not in
playing user psych games.
If one is prepared to build hardware with no BIOS (i.e. do your own
IPL), then you can get real boot times somewhere in the low end of the
single digit seconds (i.e. 2-5), assuming a “average size” application
(i.e. 3-10 sub-1MB executables and reasonably fast hardware that is
capable of supporting a large boot image, and exe’s that simply load,
and aren’t sequentially dependent on each other).
Personally, my laptop takes quite a while to boot, but it automatically
determines whether I am plugged into my home or work networks, and
configures itself appropriately (i.e. mounting different shares in each
case, etc.), once it is up it is completely ready to use as my
development system. Boot speed is highly over-rated when you have to do
a lot of mucking around after the boot is complete (even with all this
extra work it still boots in less than half the time of my other,
faster, laptop with WindowsME, which is only “dimly” aware that there
are such things as networks at all .

Conversation: QNX boot time
Subject: Re: QNX boot time
I have seen very fast (internally one of the guys here had a laptop
up and going in Photon in a very short period of time). Its all
in how you load things. Plan what needs to be started right away
and what doesn’t. E.g. On an IA device, the GUI should be started
as soon as possible, so the user can interact with it asap, however
say network communication isn’t that vital right away (its going to
take the user a few secs to go and click on the web browser) so
you can start that up after. Also starting things in the background
also can help.
