That's what it is

Not sure what you mean here, are you getting a ProDOS error only with the
card
in your system or both with and without?  With a ROM 3 and only 256k on the

card you would be a little short on memory for a full install of system
6.0.1 but fine
with system 5.0.4. With a fully loaded card in a ROM 3 you'd have enough
memory
for almost all IIgs software

This card works in any IIgs.  The jumpers are used when you add chips to
the card.
Both jumpers off with only origional 256k.
Lower jumper on when you fill the first bank which is in the top row
Both jumpers on when the card is filled.
Card works with 256k, 512k, and 1mb, however 768k is not supported
