To make the Type11 (Boot132) Boot drive (128mb or better): You will need access to a Windows machine.
* Format the USB stick in the FAT32 format. * Download Syslinux 3.63 * Expand that zipfile. In the win32 subdirectory there is an executable called syslinux.exe. At the command line, run syslinux -ma f: (assuming F: is the drive letter referring to your freshly formatted USB stick; replace with the correct one if necessary) * Copy the contents of the Type11 ISO file (not the image itself) to the USB stick, taking care not to overwrite anything that syslinux put on the USB stick (it only placed one file on the stick) * You now have a bootable Type11 (Boot132).
Insert the Leopard thumb drive into a USB slot on the right hand side of the Mini9, and insert the Boot132 thumb drive into a slot on the left. Turn on the machine, make sure USB Legacy is Enabled in the BIOS. Press 0 while booting to get the boot menu, choose USB Drive, you should see some SYSLINUX text zipping across the screen, when you get a prompt, hit enter. You'll proceed to boot up into the Leopard installer.
