Short: CompactFlash PCMCIA driver for A600/1200 Author: jaroslav.pulchart@gmail.com (Jaroslav Pulchart), based on work by Torsten Jager and Paul Carter Uploader: jaroslav pulchart gmail com (Jaroslav Pulchart) Type: driver/media Version: 1.39 Replaces: driver/media/cfd{136,137}.lha Requires: AmigaOS 2.0+, PCMCIA slot, CF-to-PCMCIA or SD-to-CF adapter Architecture: m68k-amigaos Kurz: CompactFlash PCMCIA Treiber fuer A600/1200 compactflash.device V1.39 - PCMCIA CompactFlash driver for Amiga 600/1200. Fork of driver/media/CFD133.lha. CHANGES IN 1.39 (10.02.2026) ============================ Driver: * Checking stability of I/O port access (github issue #33) Cards with unreliable data transfer are now detected and rejected to prevent data corruption. Thanks to Freddy (amigaportal.cz) for sending the CF card for analysis. Others: * git repository restructured * Rebuild by vasm 2.0d FEATURES ======== * Supports CompactFlash, MicroDrive, and various adapters (SD, MemoryStick, SmartMedia) * TD64 and SCSI emulation support * Works with fat95 filesystem for FAT32 support, not excluding Amiga native (ffs, sfs, pfs) filesystems * Serial debug output for troubleshooting (Flags = 8) * Transfer speeds up to 2.2 MB/s read, 1.9 MB/s write (in multi-sector mode if firmware supports it or with Flags = 16 override) REQUIREMENTS ============ * Amiga 600 or 1200 with PCMCIA slot (A1200 tested) * AmigaOS 2.0 or higher (3.2.3 tested) * "CompactFlash to PCMCIA/ATA" adapter card (see images/cf-type-1.jpg, images/cf-type-2.jpg) or SD-to-CF adapter (see images/sd-cf-adapter.jpg) * fat95 filesystem (disk/misc/fat95.lha) recommended INSTALLATION ============ Two versions of the driver are included: compactflash.device 11288 bytes Driver with debug to serial console flag support compactflash.device.small 8608 bytes Driver without debug to serial console support Choose based on your needs: - Use the full version if you need serial debug output (Flags = 8) - Use small for minimal memory footprint (rename to compactflash.device) Steps: 1. Copy devs/compactflash.device to DEVS: (or copy compactflash.device.small as DEVS:compactflash.device) 2. Copy c/CFInfo to C: (optional, card info utility) 3. Have fat95 installed on your system 4. 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 MOUNT FLAGS =========== Set in CF0 mountlist (can be combined, e.g. Flags = 24 for debug + enforce): Flags = 0 /* default */ Flags = 1 /* "cfd first" hack for PCMCIA conflicts with other drivers */ Flags = 2 /* unused - was "skip invalid PCMCIA signature" (v1.37+) */ Flags = 4 /* use CardResource API instead of direct chipset access */ Flags = 8 /* output init messages to serial port at 9600 baud (v1.35+ full build) */ Flags = 16 /* force 256 sector transfers regardless of card capability (v1.35+) */ Flags = 32 /* skip multi-sector override auto-detection, use firmware value (v1.37+) */ SERIAL DEBUG EXAMPLE ==================== With Flags = 8, connect serial cable and monitor at 9600 baud: [CFD] Card inserted [CFD] Identifying card...

Same behaviour as v1.33 and earlier versions. WARNING: Verify your card is capable before using for real data! Set the flag and read any text file from CF card. The content should not contain repeating 32-byte pattern after first 512 bytes. See images/multimode-issue.jpg for example of broken output. NOTE: Since v1.37, the driver auto-detects multi-sector override capability and enables 256 sector mode when safe. This flag is now only needed as a manual override if auto-detection fails. Can be combined with MaxTransfer to limit sectors per IO: Flags = 16 MaxTransfer = 0x10000 /* 128 sectors per IO (64 KB) */ Tested configurations (author's experience - your results may vary): SD-to-CF adapter (SanDisk) 32GB - Works SD-to-CF adapter (Samsung) 32GB, 64GB - Works CF cards <=4GB - Works CF cards >4GB - Not working CFINFO UTILITY ============== CFInfo displays detailed information about the inserted CF card.
