Does the card has any brand name or other markings on it? I
haven't heard of a RAM card the doesn't have the size clearly
marked, except for Oliver Klotz's cards.
As Raymond wrote, first set the switch to the r/w position. I
suggest putting the card in the 48GX's slot 2 instead of slot 1,
but indeed ignore any error message for now. Type in PINIT and
press ENTER (PINIT doesn't take any arguments). After the "busy"
annunciator turns off, press LeftShift LIBRARY (over the 2 key),
then press the PORTS menu key. You'll always see the :0: menu
label for port 0, and if a card is in slot 1, you'll also have a
:1: for port 1. With the card in slot 2, you should see at least
:2:. If you see more port labels, then each one is 128kB. If you
see only :2: for the card, then execute 2 PVARS to see whether
it's a 32kB card or a 128kB card.
32kB and 128kB cards can be used in either slot 1 or slot 2 of
either the 48SX or 48GX, but larger cards should be used only in the
48GX's slot 2. Exceptions to this are some TDS brand
multi-bank cards designed for the 48SX, and some of Oliver Klotz's
multi-bank cards with the current bank selected by switches on the
card, which work in either slot of either model.
