Was Windows fully functional when installed using XOM?
Not quite. Although the Intel-based Macs available at the time of its release — the iMac “Core Duo”, MacBook Pro, and Mac mini “Core Solo/Duo” models — were capable of booting Windows XP using XOM, video drivers were not released for the iMac “Core Duo” and MacBook Pro. Due to Apple’s introduction of Boot Camp video drivers probably never will be available for the “XOM hack”. According to the WinXPonMac wiki, drivers also were not released for the internal speakers, remote, or integrated iSight camera on any of the Intel-based Macs.
