The Asus Eee PC 1000H has an SD card reader. I read on the eeeuser.com forums that you could boot from that device.
That got me to thinking about booting BartPE from that.
I already had a BartPE CD so I just wanted to copy that to an SD card. I Googled "copy bartpe cd to usb drive" and got some pretty good hits. I chose this link.
Worked like a charm. Now I can boot BartPE from the SD card and use an external USB drive to Ghost to.
