There is: the first sector of the partition holds
boot code for OS/2. This code will be used if you
boot without OS/2 bootmanager straight from a
primary partition (I am using this with my OS/2
servers. Since there is no other OS I do not need
a bootmanager on a server ;-)

No, this job is done by "OS2LDR". The OS/2 bootmanager
only looks for this program and if it could find it
will handle loading it into memory (it does however
provide some routines to enable loading OS/2 from
extended partitions and has its own routines to
access areas on disk beyond 1024 cylinders and 512 MByte.

Is the main page for ext2os2
http://www.leo.org/pub/comp/os/os2/leo/drivers/ifs/index.html
here you will find some other OS/2 IFS (Installable File
System --- for those not known to OS/2 terminology).
