The original controller chips did have a bug but was caught and replaced before other models were impacted. Instead of just locking out the ones impacted they elected to kill it on all 4100's. So current models will work if the apporate code can be uploaded.

The code is loaded by IBM HEX which specifies a address for the hex code to load into. Without the source code you will have a large task ahead of you.

The os is broken down by platformbytes. This is imbeded into the snaps ID/BIOS. When the os is loaded it looks at the platformbytes then it has instructions for what parts are needed.

This info should get you started. It's been over 4yrs since I looked at it.

Good luck.
