Here is some more info:
The file I copied to the USB stick was
ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/8.0/8.0-RELEASE-i386-memstick.img
Actually, I don't remember how I got the image to the USB stick. I
believe I used a free tool from HP
from within Windows XP.
I will try out your method below now.

The dd command is what is used to copy the memstick.img to USB stick.
The memstick.img is created with the dd command so no compression done.
It has fixit included and is 3 times larger than the disc-1 iso file.
Thats why I download the disc-1 iso and run the script to build the img
on USB stick. So much faster this way.
So I see that both usb sticks you are using are revision rev 2.00/1.10.
But the stick that boots on your desktop will not boot on the laptop.
And the stick that boots on the laptop will not boot on the desktop.
Very strange indeed. This indicates that the pc bios are playing a big
part in which USB stick it recognizes as bootable.
