I was able to successfully boots Zeta 1.2 as a vm guest in Hyper-V in Windows 8.1 without any safe mode options.
Use bchunk for windows to extract the .bin into two iso images. Set cdrom 1 as highest in the boot order, and set cdrom 1 as the 2.88mb boot iso, and set the larger iso as cdrom 2. When the loader opens, the cd-rom volume should be selected. It will be in grayscale and 640x480 by default. You can navigate the install with the keyboard, but use Tab and Enter instead of Spacebar to select anything, since mouse movement is very slow.
