While freeBOOT requires a dual NAND solution such as the Cygnos360 or xD modchip, XBReboot on the other hand can be flashed directly to the Xbox 360 internal NAND flash but only available as a 16MB flash dump for Xenon motherboards at the moment. The new features are as follows: Harddisk authentication disabled. The Xbox 360 will now accept any SATA hard disk. Removed XEX signature checks. This is what makes XDK (Xbox360 Development Kit) homebrew possible. Removed LIVE/PIRS signature checks. Extendable patch system."
