OpenSolaris's USB image file ( which often distributed with '.usb' extention ) is just 'dd' image of root partition. But it is not enough to create bootable USB stick since do not contain required data such as MBR, Grub and Partition Tables.
'usbcopy' shell-script on OpenSolaris generate such data using 'grub', 'fdisk' and 'format' command internally. I have to generate using other way on Windows box.
When developing v0.02 of USB Creator, I made some pattern of required data ( I call this 'head image' ) and flash it before USB image. Header images included in OsolLiveUSB002.zip may be useful for 'dd'-command user.
Please try to flash following procedure below;
- Download .usb image ( this example is for Ohta-san's b123 image )
- Download OsolLiveUSB002.zip ( not v0.03 !! ) and extract
- De-compress header images
- Flash your USB stick with concatinating header and .usb image I used 2GB-Stick of head image this time;

Thank you!
ah.. so that's why simply dd'ing the image to disk didn't work, thanks :)
thank you very much, i've been looking all over the net for this.
by the way, i simply can't understand why the folks at genunix don' generate dd'able usb images..
Hi jhol, Robert, casaubon,
Thanks for visiting my blog.
And I am happy that you got over some difficulty :)
you're a lifesaver. i finally was able to install opensolaris. unfortunately i found that it is not yet ready for laptop usage. it's at the stage where linux was some five years ago. wpa and bt mouse was a pain to get working. i think i will stick with linux for a few years more until it (hopefully) catches up.
