This isn't true generally, although slowing down the system may have made
your specific problem go away.  I boot my system from UniDisks all the time,
as do thousands of others, without resetting the system speed to "normal".

In fact, there's a whole lot of expensive hardware in the IIgs to make sure
that the system isn't "too fast" for older peripherals.
