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: 1.42 Replaces: driver/media/cfd141.lha Requires: AmigaOS 2.0+, PCMCIA slot, CF-to-PCMCIA or SD-to-CF adapter Architecture: m68k-amigaos Kurz: CompactFlash PCMCIA Treiber A600/1200 compactflash.device V1.42 - PCMCIA CompactFlash driver for Amiga 600/1200. Fork of driver/media/CFD133.lha. CHANGES IN 1.42 (16.05.2026) ============================ compactflash.device: * Autoboot from RDB at cold-boot: a bootable RDB partition on the inserted card boots straight into Workbench. All RDB partitions appear at cold start without `DEVS:DOSDrivers/` entries. Filesystem handlers stored on the card are loaded automatically. Requires `ptable.library` to be ROM-resident; disk-only install is mountable-only without it. * Stricter CIS gate: as the CIS detection code improved over time, the fallback that accepted cards without a readable `CISTPL_FUNCID` was dropped. Such cards now fail the CIS gate, freeing them for their proper driver. Others: * Release archive version and compactflash.device version are now tracked independently * New distribution layout: two build flavors per CPU tier are stored in dedicated folders: cfd/full// - debug-capable (serial output enabled with Flags=8) cfd/small// - no debug code where is 68000 (any 68k) or 68020 (68020+) 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 ============ The archive ships two flavours (full / small) and two CPU tiers, each as a sysroot ready to drop onto SYS:. 68020+ (A1200 stock, 68020+): full/68020/devs/compactflash.device debug-capable small/68020/devs/compactflash.device no debug code full/68020/libs/ptable.library debug-capable small/68020/libs/ptable.library no debug code 68000 (stock A600, 68000+): full/68000/devs/compactflash.device debug-capable small/68000/devs/compactflash.device no debug code full/68000/libs/ptable.library debug-capable small/68000/libs/ptable.library no debug code Choose based on your needs: - Use the full flavour if you need serial debug output (Flags = 8) - Use small for minimal memory footprint (no debug strings/code) Steps for normal mount-only use (no autoboot): 1. Drag the contents of // onto SYS: the inner devs/ and libs/ drawers map onto SYS:Devs/ and SYS:Libs/ directly. - A1200 (68020+): full/68020/ (or small/68020/) - A600 (68000+): full/68000/ (or small/68000/) 2. Copy c/CFInfo to C: (optional, card info utility) 3. Have fat95 installed on your system 4. Mount the drive by double-clicking Storage/DOSDrivers/CF0 For autoboot, see the AUTOBOOT section below. For OS 3.5+: Copy def_CF0.info to sys:prefs/env-archive/sys and env:sys AUTOBOOT/AUTOMOUNT ================== Autoboot is now provided by a separate ptable.library shipped under //libs/. At Kickstart cold start the compactflash.device opens ptable.library and asks it to walk the RDB on the inserted card, load any filesystem handlers carried in into FileSystem.resource, and publish each partition via AddBootNode (bootable) or AddDosNode (non-bootable). Both the compactflash.device and the ptable.library MUST be ROM-resident for this to work. A disk-only ptable.library install is silently ignored. The device driver still works as a normal mount-only device. On cold boot the driver tolerates slow cards and adapters by polling for up to ~1.8s. When a card is present and stable the delay is zero. More details can be found in fat95's guide and GitHub project page. 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.

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.
