The way I did was using an existing mac.

I copied the IPC-DL.ISO file to the desktop

I formatted my 8gig usb imation drive on the mac. 4 gig works too..on the regular IPC.

Using the disk utility, I restored the .iso file onto my USB drive.

Then I used OSX86 tools , "Install EFI/ run fdisk" on the USB drive.

Done.

My USB thumb drive has IPC on it, it boots up FAST, I can install IPC not spend time
with long periods of wait bootup time. great for experimenting on many PCs.
