ipxe on usb

[robinsmidsrod]

The first thing you need to do is to create the ipxe.usb file. You can do that with make bin/ipxe.usb or you can download it from http://rom-o-matic.eu/ if that is easier for you. This file is a raw block device image, and does not contain a valid filesystem, but specialized content that boot iPXE.

You'll need to use the entire USB stick for it, as there is no (useful) partition table in the disk image. On a Linux machine, the way to transfer the image is to figure out which device node is your USB stick, and completely overwrite it with the iPXE image file.

Running ls -l /dev/disk/by-id should list the disks recognized on the system. Ignore all the -part files (they represent partitions, not whole disks). Then you do the following to write the image out: dd if=path/to/ipxe.usb of=/dev/disk/by-id/my-usb-stick-name (replace with what you found above in the output from ls -l)

Be careful not to overwrite the wrong device, or you'll need to recover its contents from a backup.
