+Short:        CompactFlash PCMCIA driver for A600/1200
+Uploader:     jaroslav.pulchart@gmail.com (Jaroslav Pulchart)
+Author:       jaroslav.pulchart@gmail.com (Jaroslav Pulchart), based on work by Torsten Jager and Paul Carter
+Type:         driver/media
+Version:      1.34
+Replaces:     driver/media/CFD133.lha
+Requires:     AmigaOS 2.0+, PCMCIA slot, CF-to-PCMCIA adapter
+Architecture: m68k-amigaos
+Kurz:         CompactFlash PCMCIA Treiber fuer A600/1200
+
+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 */
