*Firmware versions 1.0.5 and 1.0.8 and 1.1.1 available.
 
*Runs VxWorks
 
*[http://www.arm.com/products/CPUs/ARM946E-S.html ARM946E-S]
 
*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

**ewhat working, see [http://stack.dataghost.com/40D.avi this movie]. If it's not clear enough, [http://www.youtube.com/watch?v=OlKywUVFJW4 this one] or [http://stack.dataghost.com/40D-movie2.avi this one] (both are the same) should convince you.
 
*Live view contrast AF
 
**Might already be present in the firmware but that's just a guess based on some strings.
 
*AF microadjustment
 
**Some strings present but functionality likely not implemented.
