67 I have tried it on two boxes, they are both small units without CD
68 1.) First is an older box that can not boot from Gentoo ISO USB generated with "dd"
69 BIOS setting are:
70 USB-ZIP
71 USB-FDD
72 Hard Disk
73
74 2.) The second box is an ATOM-330 and the same USB boots OK.
75
76 So the issue might be with the Bios on the first box.
