Yes.

resc1200.bin is an uncompressed image of a MS-DOS filesystem containing
the kernel but not root.bin. resc1440.bin is an uncompressed image of an
MS-DOS filesystem containing both the kernel and root.bin . root.bin is
a compressed Minix filesystem image, and is uncompressed to 1.44MB when
it is loaded, even if it is loaded from a 1.2MB disk.
I could have compressed resc1200.bin and resc1440.bin in the FTP archive,
but that would have added a task for the person who is writing them from
a DOS system - they would have had to find and use the DOS gunzip program.
El Torrito format Bootable CDs store an image of resc1440.bin on the CD,
and BIOS emulates a floppy using this image while booting.
