Gemdos filesystem is quite similar to MSDOS, but there's some differences
according to disktype project:
http://disktype.sourceforge.net/doc/ch03s03.html

At least bootsector has different marker.

I booted FALCON kernel with different TT-ram values (with loadbsd -T flag)
and for a quick test at least kernel booted every time. However it would be
nice to know what happens with real amount of 2MB TT-ram... I'm not sure how
well NetBSD runs on 4/4MB machines - at least Frank's TT failed to boot
NetBSD (with ATARITT kernel, but BOOTX worked).
