PURPOSE

	The FileSystem.resource is where boot disk drivers rendezvous
to share file system code segments for partitions specified by
dos type. Prior to V36, it was created by the first driver
that needed to use it. For V36, its creation is ensured by the
rom boot process.
CONTENTS
The FileSystem.resource is described in the include file
resources/filesysres.h. The nodes on it describe how to
algorithmically convert the result of MakeDosNode (from the
expansion.library) to a node appropriate for the dos type.
FileSysEntry
fse_Node on fsr_FileSysEntries list
ln_Name is of creator of this entry
fse_DosType DosType of this FileSys: e.g. 0x444f5301
for the fast file system.
fse_Version high word is the version, low word is
the revision.
fse_PatchFlags bits set for those of the following that
need to be substituted into a standard
device node for this file system: e.g.
$180 for substitute SegList & GlobalVec
fse_Type device node type: zero
fse_Task standard dos "task" field
fse_Lock must be zero
fse_Handler for V36, if bit 31 is set, this is not
an AmigaDOS partition.
fse_StackSize stacksize to use when starting task
fse_Priority task priority when starting task
fse_Startup startup msg: FileSysStartupMsg for disks
fse_SegList segment of code to run to start new task
fse_GlobalVec BCPL global vector when starting task
no more entries need exist than those implied by fse_PatchFlags,
so entries do not have a fixed size. For V36, for example, the
entry for the fast file system (fse_DosType 0x444f5301)
contains a zero fse_PatchFlags, and thus no entries beyond that.
