Create a bootable USB drive!

Descrption:
I had to search all over for this information, so I stole a little here, borrowed a little there, and made up what I couldn't find, to get it all in one place.
Hopefully, this will save everyone some time.

First, this is PE version 2.0, and earlier versions will not work. I do not/will not work with BartPE, so I haven't a clue what needs to be done in that environment.

Your USB and the port it is using must be USB 2.0. I don't know if USB 1.0 will work slowly, or not at all.

I'm assuming you've created a bootable PE Version 2.0 CD.
I used the drive letters that my computer assigned to the devices. Yours may be different.
C:=local hard drive
D:=CD/DVD drive
E:=USB Thumb drive
X:=PE's RAM disk

You need to assure that you select the proper disks, as you will be erasing and formatting the thumb drive. I will not be responsible for any data loss or woes you encounter!

You'll need MagicISO, to extract all folders and files (including hidden files) from your CD to a file on your C: drive (I used c:\bootusb)
(You probably already have these files in a folder, somewhere. you needed to use them to create the ISO. If not, extract them before you boot the PE CD).

Boot your PE version 2.0 CD
type these commands:
disk part
select disk 1 (this was my USB drive. type in "detail disk" to be sure you've selected the USB drive)
clean (you are erasing the selected disk. I hope you got it right!)
create partition primary
select partition 1
active
format fs=fat32 (this takes a while)
assign
exit

You're now back at the command prompt, and need to copy the files from the folder you created on your hard drive to the USB drive.
xcopy c:\bootusb\*.* e: /h /e (this also takes a while)

You can't copy the files from the RAM drive, as they're in use by PE
I don't think (but haven't tried) you can copy them from the CD, as they're compressed. (

Good luck, and I hope to have saved someone a bit of trouble figuring this out.

Intel Atom

Introduction

For a few months, we’d been hearing talk of a new dedicated Intel processor for MIDs (Mobile InternetDevices), intended to compete with ARM processors. Initially known by the names Silverthorne and Diamondville, the processors in this new line will be called "Atom". These chips have a few surprises in store.

Interesting and Surprising Choices
Atom CPUs are surprising for more than one reason: they have modern functions (EM64T, SSSE3, etc.) grafted onto an older architecture The Atom is the first in-order x86 since the Pentium. Power management and fabrication costs are the two imperatives Intel seems to have been guided by, at the expense (with no attempt made to hide it) of performance. So, no, don’t expect a competitor to Core 2 Duo. But what does the Atom really have to offer? We’ll see that as this piece unfolds.

Intel versus AMD Processor

This evaluation of current desktop processors utilises over 60 benchmark tests including office and multimedia software, 3D games, Internet applications, video rendering and compression. We have used benchmarks that are relevant to a range of market sectors in order to get a balanced view of CPU performance. However, in an ideal world, you should also run your own mission-critical applications on any processor that you're considering.

Of course, performance is only one aspect of a processor purchase decision. For example, the Athlon 64's support for the NX (No Execute) feature safeguards it from certain virus attacks, and could be reason enough to choose an AMD processor. And if you're after a quiet PC, then AMD's chips have clear advantages over Intel's latest 'Prescott' Pentium 4. The power consumption of the Athlon 64 is lower than that of the Pentium 4 thanks to AMD's use of Silicon-on-Insulator (SOI) technology. The Athlon's 64's 64-bit capability is also a potential advantage, although this feature remains largely unused because of the missing operating system support -- 64-bit Windows XP has now been delayed until 2005.

System	Idle	Max
Athlon 64 3800+ (Nforce 3)	91W	172W
Athlon 64 3800+ (KT800 Pro)	82W	162W
Pentium 4 560 (925X)	155W	258W
