compactflash.device V1.34 - PCMCIA CompactFlash driver for Amiga 600/1200

Fork of driver/media/CFD133.lha with improvements for >4GB CompactFlash cards.

CHANGES IN 1.34 (22.10.2025)
============================
* Made >4GB CompactFlash cards usable
  - Workaround for "get IDE ID" on large capacity cards
  - Limited multi-sector IOs for reliability on >4GB cards
* See README.md for detailed configuration options

FEATURES
========
* Supports CompactFlash, MicroDrive, and various adapters (SD, MemoryStick, SmartMedia)
* TD64 and SCSI emulation support
* Works with fat95 filesystem for FAT32 support
* Supports cards up to 4GB reliably 
* Transfer speeds up to 2.2 MB/s read, 1.9 MB/s write (with MaxTransfer > 0x200 if reliable and working CF firmware)

REQUIREMENTS
============
* Amiga 600 or 1200 with PCMCIA slot
* AmigaOS 2.0 or higher (3.2.3 tested)
* "CompactFlash to PCMCIA/ATA" adapter card
* fat95 filesystem (disk/misc/fat95.lha) recommended

INSTALLATION
============
1. Copy devs/compactflash.device to DEVS:
2. Have fat95 installed on your system
3. Mount the drive by double-clicking devs/CF0

For OS 3.5+:
  Copy def_CF0.info to sys:prefs/env-archive/sys and env:sys

HISTORY
=======
v1.34 10/2025 - >4GB CF card support (Jaroslav Pulchart)
v1.33  1/2017 - Init reliability fix (Paul Carter)  
v1.32 11/2009 - Error messages, open source release (Torsten Jager)
v1.31 11/2009 - Memory mapped mode fix
v1.30 11/2009 - Major API rework for ROM use
...
(see README.md for complete history back to v1.01 from 2002)

WORKAROUNDS
===========
For PCMCIA conflicts with other drivers:
  Flags = 1    /* enable "cfd first" hack */

For cards without valid signature:
  Flags = 2    /* skip invalid PCMCIA signature */
