It's fully booted in Vista64 in ~1.5 mins.
Any suggestions on how to eliminate the 45 secs delay?.
That will allow you to see the BIOS progress messages. Save and
exit. Then tell us what you see. You should see text messages,
first for disk detection on the Southbridge, and then additional
messages for any auxiliary controllers.
I presume, when you push the front power button, that the video output
is enabled pretty well instantly.
You can go into the BIOS, and disable unneeded hardware. And
sometimes that gives the desired speedup at POST. It might even
be something like the BIOS RAM test, that is eating a few seconds.
But when you look at the text on the screen, it might become
more apparent what is going on.

I disable "Full Screen Logo".
The system still sits there for 45 secs without any activity.
Contrary to your presumption Paul, the video output is *not* "enabled pretty well instantly".
It's blank until the 45 secs is up. The monitor even states No Signal during this period.
After this time, some messages are displayed but they are hard to read because they appear and disappear so quickly.
The actual boot phase, once it's begun, only takes 45 secs.
Any ideas?.
Btw, I'm using BIOS v605
A poster here, mentions a "37 second delay" when using ECC RAM. Are you
using ECC RAM perhaps ?

The reason I'm asking questions, is to distinguish the various delay type
problems.
1) Some boards, you press the power button, and no fans spin or anything.
The user sometimes waits for a period like an hour, and suddenly the
computer fans start, video appears etc. This is a case where PS_ON#
is not being delivered to the power supply for some reason, and it
could be a motherboard or a power supply issue.
In some cases, this has turned out to be because the motherboard
doesn't actually know the power went off, and the motherboard thinks
the main power has always been on. The board doesn't initialize properly,
as a result of failing to notice the power went off. This can be caused
by leakage down the monitor cable. A user noticed, that his board would
start more normally, if the monitor cable was disconnected, before
attempting to start the computer.
2) Some motherboards do a "double start". The power comes on, goes off
after a couple seconds, and then comes on again. Sometimes that behavior
can be cured with a different BIOS version. It is unclear, whether Asus
knew this was happening when the BIOS was released or not. It seems to
be a fairly common problem, and the fact that it can be cured with a
different BIOS, suggest more QA work is needed.
3) On some, if you press the power button, the BIOS proceeds normally.
Video appears in maybe 5 seconds. But the screen may blank, and the
cursor may sit in the upper left corner, blinking, for 30 seconds or
more. Sometimes this is due to waiting for a hard drive to become ready.
Other times, it could be interference from some USB device that looks
like a USB mass storage. A card reader is an example of a potential
USB mass storage device.
A PCI port 80 card can be used, as an additional monitoring mechanism.
A card can be purchased for as low as $20, and you plug it into the
#1 PCI slot. The BIOS writes "progress" codes to the two digit display
on the card. (Some motherboards have the two digit display actually
soldered right on the motherboard, and for those motherboards, no
card needs to be purchased.) In terms of utility, the PCI port 80 card
is almost useless, as the display codes are poorly documented, and
many times someone will ask what a code means - I look it up and the
doc says "Reserved". But for the problem you are having, being able
to watch the display, would tell you whether the system is frozen
for the 45 seconds, or is busy doing stuff.
Looking at a few articles on vip.asus.com, the P5E seems to have a
number of faults. It seems to have just outright died on a number
of people. But the above post, is the first one that mentions a
delay.
Perhaps you could elaborate further on exactly how it starts up
and what you see on the screen.
You can use the "Pause" key, to stop the printing on the screen,
so you have enough time to read the text. I know some BIOS don't
wait very long, and you'd need ninja reflexes to hit the Pause
at exactly the right time.
