The FW change does not affect the calibration constants nor options however you might end up with a black screen, the main issue here is that the 8753E and higher used a LCD rather than a CRT display, it therefore uses a different GSP which might cause a problem?

?Hi!
I'm running FW 7.14 on my 8753D Option 000 CPU upgrade. The FW 7.14 is the latest release for the 8753D.
However, it has been mentioned several times that this CPU board can use the 8753E firmware. If I try to load the 8753E's FW 7.48 or even the 8753ES' FW 7.74, what can possibly go wrong:
1. options are erased and will need to enabled them again using the unlock codes?
2. Internal HW calibration settings are gone (this would be a major disaster)?
3. nothing of the above, the FW installation will warn me that its incompatible and no damage shall occur?
The 8753D shows only two traces (channels) and I would appreciate it very much the 4 channel feature of the 8753E/ES :)
Thanks for the help!
