Partition-table library

Short:        Partition-table library
Author:       jaroslav.pulchart@gmail.com (Jaroslav Pulchart)
Uploader:     jaroslav pulchart gmail com (Jaroslav Pulchart)
Type:         util/libs
Version:      20261007
Replaces:     util/libs/ptable.v20260930.lha
Requires:     AmigaOS 2.0+
Architecture: m68k-amigaos
Kurz:         Partitionstabellen-Library

ptable.library is the AmigaOS partition-table library (one place that parses
RDB, MBR, GPT and flat layouts and publishes every partition into a shared
partition.resource) so a device driver and a filesystem handler never each
carry their own partition parser.

It was assembled from existing code: the library framework and RDB
cold-boot path came from compactflash.device (pre 2.0), the MBR/GPT
scanning from fat95 (pre 4.0).

Consumed by
* compactflash.device 2.0+ (driver/media/cfd) and
* fat95 4.0+ (disk/misc/fat95).

COMPONENTS IN THIS RELEASE
==========================
- ptable.library 2.2 (03.10.2026) (new)
- lsptres 1.2 (03.10.2026) (new)

WHAT'S NEW (07.10.2026)
=======================

Install:

* New Installer script.
* Reworked icon positions.

ptable.library 2.2:

* Fixed SCSI reads for partition detection.
* Serial debug output ends lines with LF alone.

Tools 'lsptres 1.2':

* Improved paging.
* Output lines end in LF alone.

WHAT IT DOES
============
* Cold-boot RDB autoboot: boot directly from an RDB-partitioned card
  (requires the library ROM-resident).
* DOS-time scanning and automount: discover and mount hotplugged
  RDB/MBR/GPT/flat cards, via the consuming driver.
* Publishes a shared partition.resource that any driver or handler can read
  instead of parsing the partition table itself.

REQUIREMENTS
============
* AmigaOS 2.0 or higher.
* A consumer that uses the library: compactflash.device (driver/media/cfd)
  or fat95 (disk/misc/fat95). ptable.library on its own does nothing.
* For cold-boot autoboot the library must be ROM-resident (Remus / Capitoline).
  A disk-loaded copy is used for DOS-time scanning only.
* Installer 43.3 or newer for Install (without it, install by hand).

INSTALLATION
============

* Double-click Install. It detects the CPU, copies ptable.library to
  LIBS: (small variant, full in Expert mode) and optionally lsptres
  to C:.

  I recommend putting ptable.library in ROM as a resident module.

By hand:
1. Copy <flavor>/<cpu>/libs/ptable.library to LIBS:.
     - 68020 or higher: 68020/
     - 68000/68010:     68000/
     - full (serial debug output), small (no debug code)
2. Copy c/lsptres to C: (optional, lists partition.resource).
3. For cold-boot autoboot, put ptable.library in ROM with Remus or Capitoline.

LSPTRES
=======
lsptres dumps the current contents of partition.resource (the partitions the
library has published: name, DOSType, geometry, and the resolved mount
Flags/CONTROL). Run it with no arguments:

  lsptres

See docs/lsptres.guide for the full output description.
