Here's a small ISO containing memtest86 (and more). This ISO is a "hybrid I= SO" meaning that you can either burn it to CD/DVD and boot off it, or you c= an dd(1) it to a thumb drive and boot off that. http://sourceforge.net/projects/druidbsd/files/Druid-0.0.iso/download Here's the instructions for writing it to USB (you likely already know how = to write an ISO to CD/DVD): 1. Download Druid-0.0.iso 2. Insert thumb drive 3. Execute: camcontrol devlist NOTE: find the `daN' device associated with your thumb drive 4. Execute: dd if=3DDruid-0.0.iso of=3D/dev/da5 NOTE: assuming `da5' is your thumb drive --- At this point, your thumb drive is ready to rock and roll --- Continue on to create a 2nd [visible] partition beyond the primary bootable= [invisible] partition (allowing you to use the remainder of your thumb dri= ve for usable storage)... 5. Execute: echo "p 2 0x0c * *" | fdisk -f - /dev/da5 NOTE: again, assuming `da5' is your thumb drive 6. Execute: newfs_msdos /dev/da5s2 NOTE: again, assuming `da5' is your thumb drive That's it. You now have a thumb drive with: a. An invisible boot partition for booting into Druid (a disc full of tools= ). b. A visible partition for storage, usable under Mac, Windows, Linux, and U= NIX. NOTE: This won't work with just ANY iso file, just ISOs that have been post= -processed with ISOLINUX's isohybrid utility. -- Devin >=20 > On 04/26/2011 07:35, Mikael Bak wrote: > > C. P.
