With the following labels, my Mac G4 AGP
http://www.everymac.com/systems/apple/powermac_g4/stats/powermac_g4_400_agp.html
can load ofwboot.xcf from MSDOSFS (FAT16) on wd1 disk
and a kernel in wd1a boots fine. (wd0 disk still has MacOS)

IIRC, I created MSDOSFS by "newfs_msdos -s 48132 /dev/rwd1e".

Boot messages (mostly typed from screen) are following.
Note actual typed boot command is "boot ultra1:,ofwboot.xcf -c".
(-c is specified to pause boot to read messages)
