As the others say this is normal, standard trapdoor ram upgrade will disable the PCMCIA slot when more then 5.5mb of ram is used.
You'll either need to disable some of the ram with a jumper setting on the card or use a 4mb simm.
Your other option is to get an accelerator card (such as a Blizzard 1230)that used 24bit memory addressing thus not conflicting with the PCMCIA port.
