DOS Compatibility Card: PC Control Panel Memory Dimmed (3/94)


The PC Control Panel on my Quadra 610 with the DOS Compatibility Card has the memory section dimmed. I could change the RAM amount in this control panel at one time. How can I make this section of the control panel active again?

The DOS Compatibility Card for the Quadra 610 and Centris 610, comes with a 72 pin SIMM slot. When the unit is shipped there is not a SIMM in the slot. When the slot is empty, the DOS Compatibility card uses the RAM installed in the Macintosh. When it uses memory from the Macintosh, the PC control panel allows you to pick how much of memory the DOS Compatibility Card uses. However, if a 72 pin SIMM is added to the DOS Compatibility Card, memory is not shared so memory section of the PC control panel dims. Even with the memory section dimmed, it displays the word SIMM to let you know it is using a SIMM located on the DOS Compatibility Card.
