fat95 - Win95/98 compatible FAT filesystem handler for AmigaOS. Fork of disk/misc/fat95.lha.

CHANGES IN 3.21 (18.04.2026)
============================

This release focuses on stability and compatibility improvements across
both CPU tiers (68000/68010 and 68020+)

* Improvements
  - Fixing an unaligned long-word compare in the NTFS boot-sector
    check that could raise an Address Error on 68000/010.
  - GPT partition detection (3.19+) now follows the AmigaOS
    register-preservation rules; a violation could have corrupted
    caller state after a mount.
  - Partition state is reset before every mount attempt, so a failed
    or rejected probe can no longer influence the next one.
  - GPT FAT allowed partition types GUIDs are now both Microsoft Basic Data
    (EBD0A0A2-B9E5-4433-87C0-68B6B72699C7) and EFI System Partition
    (C12A7328-F81F-11D2-BA4B-00A0C93EC93B).

* CPU-tier builds
  - fat95 now ships in two CPU tiers; copy the one matching your
    CPU to L:fat95:
      l/68020/fat95 - A1200 stock + 68020+ accelerators (030/040/060)
      l/68000/fat95 - stock A500 / A600 / A1000 / A2000 / CDTV
  - 68020+ build is slightly smaller thanks to native 32-bit math.
  - The $VER: string is tagged [68020] or [68000] so `version l:fat95 full`
    show which tier is loaded.

Purpose
=======

"fat95" is a DOS handler to mount and use Win95/98 volumes just as if they were
AMIGA volumes.

System requirements
===================

* every AMIGA, OS 1.3+ (OS 2.0+ for full functionality)
* a suitable device file for low level disk access, like the
  mfm.device for floppies, compactflash.device for CF in PCMCIA

Features
========

See fat95.guide for full documentation.

* Workbench and applications support
* Diskchange autosense
* Format type autosense: FAT12, FAT16 and FAT32
* MBR and GPT partition table support
* Simple LINUX style partition selection or manual definition
* Up to 4 GBytes of partition size for FAT16
* Large harddisk support via TD64 or direct SCSI
* Long filenames (up to 104 chars for now)
* Inquiry, read, write, and maintenance access
* Built-in error check utility
* Disk formatting using the OS 2.0+ format command
* MS-DOS 8.3 downward compatibility
* User definable language and code page
* Date range Jan 1st, 1980 through Dec 31st, 2107
* Extended datestamp support: creation date and time, last accessed date
  (written automatically, readable as file comment text)
* Volume serial number as name for unnamed volumes
* Automatic directory optimization
* Written entirely in assembly language
