- Not entirely true :) If the card has no valid CIS (Card Information
- Structure), then the system makes an attempt to size it as a RAM card.
- If this was not true, you could not use those less expensive PSRAM cards.
- If you have an SRAM card, it is preferrable to run PrepCard on it, but
- if you have a PSRAM card, it would be very clumsy if you had to run
- PrepCard on it prior to using it as RAM (PSRAM cards have no battery,
- so would lose the information after power down).
