Korg i5M system info

I would like to find out the OS version of this i5m module I've purchased. What are the magic steps? Can I update the OS, how? I cannot find any of this info in the manual.

I found that if I hold down the GLOBAL button while powering up, it will briefly show the OS info.

ahhh an oldie but goodie. had one for years.
there is no way to update the system that i remember.however there were some programs that would allow me to write edit and load styles. this machine was pretty powerful for its time. it was the module version of the i5s keyboard. made alot of money withe these.
