LaserWriter Pro 630: No Change to Serial Settings in ROM Revisions

I had my LaserWriter Pro 630 repaired and the motherboard was replaced. The new motherboard has v2.0 ROMs, whereas my original had v1.0 ROMs. I think the new ROMs have changed the serial settings at switch positions 0 and 2. Does this new set of ROMs change the settings?

At switch position 0 and 2, both sets of ROMs configure the serial port as documented in the manual:

Switch Position 0    
1.0 ROMs            2.0 ROMs
--------            --------
PostScript          PostScript
RS-232              RS-232
9600 Baud           9600 Baud


Switch Position 2    
1.0 ROMs            2.0 ROMs
--------            ---------
PostScript          PostScript
RS-232              RS-232
19200 Baud          19200 Baud
