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

CHANGES IN 3.22 (16.05.2026)
============================

This release improves ROM resident handling:

- ROM resident installation now register FAT\0 through FAT\8 in
  FileSystem.resource at boot, so any partition with one of those
  DosTypes, whether RDB auto-mounted or mounted later via a
  mountlist / mount command, uses the ROM handler directly and
  skips loading L:fat95 from disk. Previously the ROM resident
  registration didn't actually run at boot, so even with fat95
  baked into a Kickstart ROM every FAT mount fell back to loading
  L:fat95 from disk.

- New c/lsfsres tool lists every entry in FileSystem.resource with
  DosType, version, SegList address, handler name, and a [ROM]/[RAM]
  tag. Useful for confirming which filesystem handlers are active
  and whether they come from ROM or disk.

and contains internal microoptimisations and minor size reductions:

- Several dozen inner loops optimised for both CPU tiers.
- Directory block clearing and file delete are faster on 68000.
- FAT entry reads on 68020+ use fewer instructions.
- SCSI READ10/WRITE10 command setup now uses a shared helper.
- GPT partition GUID matching is now table-driven.

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
