What is a .S28 file?
S28 is a Motorola S-record firmware file with 24-bit addresses.
- Did you know
- Records with 24-bit addresses suited Motorola’s 68000 family, whose external address bus was exactly 24 lines wide.
- The S28 variant uses a 24-bit address field, extending an S-record’s reach to 16 MB of memory.
- PROM programmers of the era read S-record files directly, burning the decoded bytes into PROM and EPROM chips.
- What Analyser reads
- Inspect virtual-machine descriptors (VMware .vmx, VirtualBox .vbox, OVF/OVA), disc images (Nero .nrg, Alcohol .mds/.mdf, CloneCD), embedded firmware (Intel HEX, Motorola S-record, UF2, ELF/AXF, Device Tree Blobs, U-Boot uImage), partition tables (MBR/GPT with GUIDs), Linux filesystem superblocks (ext2/3/4, SquashFS, cramfs, romfs) and Windows imaging (WIM/ESD) - reading headers directly, no upload.
- Depth of analysis
- .S28 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .S28 file
- Drag a .S28 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
