I think you also need to add a boot sector to the drive. On my 64-bit system:

#dd if=/usr/lib64/syslinux/mbr.bin of=/dev/sdc
  

After doing your suggestion I get
same thing it just sets there with a blinking cursor.

I took an older 512MEG usb instead of my 8 GIG one,
did the exact same steps and I get
Could not find boot image: linux

I copied all files what is missing?


It was just a guess. There were several more steps I have needed to do in the 
past in order to get Fedora Live CDs to boot off of thumb drives. I wish I 
could find the link but all I find now are instructions to use a Fedora script 
to create the thumb drive -- a script that doesn't seem to be immediately 
available for CentOS or RHEL.

 Interesting on the 512M device I copied the vmlzi586 to linux 
 and it starts to boot great...
 Now how do I get the 8GIG part to boot?

Is there a valid MBR on the flash device?
