- Firmware versions 1.0.5 and 1.0.8 available
- Runs VxWorks
- 256MB memory
- Uses AUTOEXEC.BIN instead of DISKBOOT.BIN
- Needs to be enabled in NVRAM
- Requires an EOS_DEVELOP disklabel and BOOTDISK 'signature'
- Can boot from FAT32
- File format unknown, possibly needs a header but unlikely (probably a plain binary)
- Runs from 0x800000
Possible extra functionality
- Movie mode
- Live view contrast AF
