You should be able to install the disk on a different system.

This needs tracking down, and I don't have a failing board.

You should also be able to change the default console used by the boot
floppies!

The information is held in a table near the start of the floppy image:

00000400  eb 4a 89 f6 d1 b6 86 78  44 00 00 00 00 00 00 00  |.J.....xD.......|
00000410  05 00 00 00 00 00 00 00  80 25 00 00 00 00 00 00  |.........%......|
00000420  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|

The 80 25 is the baud rate (0x2580 = 9600)
Byte 414 is the console, IIRC 'com0' is 1.
The IO addr seems to be taken for a bios table at 0x400
