- 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.
