Version 1.1 of rdb Distribution is 2-Feb-94
------------------------------------------------------------------------
rdb - edit the RDB (Rigid Disk Block) area of an AmigaDOS disk device
This program functions in place of HDToolBox for controllers which
support the RDB area, but refuse to work with HDToolBox. My IVS
TrumpCard is one such beast. rdb allows you to tweak most RDB
parameters (including those HDToolBox won't let you touch), so if you
don't know what you are doing, I don't recommend you use this program.
Usage:
rdb disk.device unit [option | keyword=value . . . ]
Where
disk.device is the physical disk device driver
unit is the physical disk unit on that driver
option can be any of:
-rigid = edit fields in the Rigid Disk Block
-part NAME = modify partition table parameters of NAME
-newpart NAME = add new partition NAME to the RDB
-promote NAME = make partition NAME first to be mounted
-extract DOSTYPE = extract filesystem to a file
-avail = report next available block in RDB
-seglist = show seglist addresses for filesystems
-help = give more help
keyword can be any of:
Fields in the RDB disk header
HostID BlockBytes RigidFlags BadBlockList PartitionList
FileSysHeaderList DriveInit Cylinders Sectors Heads
Interleave Park WritePreComp ReducedWrite StepRate
RDBBlocksLo RDBBlocksHi LoCylinder HiCylinder CylBlocks
AutoParkSeconds DiskVendor DiskProduct DiskRevision
ControllerVendor ControllerProduct ControllerRev
Fields in the Partition header
Next Flags DevFlags DriveName Surfaces BlocksPerTrack
Reserved PreAlloc Interleave LowCyl HighCyl NumBuffers
BufMemType MaxTransfer Mask BootPri DosType
Lackage:
The program is able to dump filesystem handlers from the
rdb area to a regular Dos file. It should also allow
transfers in the opposite direction. ie: Installation of
a new filesystem handler in the rdb area. I intend on
adding this to rdb when I get back to it.
Coolness:
rdb is able to repair damaged RDB areas (well, it can fix
the checksum on RDB blocks for you).
Parameters to rdb may appear in any order and are case-
insensitive. Also, the "=" is optional for settings. Rdb
will ask before making any changes to your disk structure.
Example:
Say you want to change the boot priority of DH0: on your
machine using scsi.device, unit 6
rdb scsi.device 6 -part DH0 bootpri=10
