ROS7 x86 32bit hardware

Can anyone please advise if ROS7x is x86 32bit support continued? ISO is 64bit only based on messaging i am seeing when attempting CDROM install. And i have never successfully managed to get any x86 hardware to pull a PXE from Netinstall. Any hint on progress or abandon? Just looking to use a little old bit of kit up on my roof for GPS time synch.

Thanks
