PCMCIA unfriendly accelerator (like M-Tec 1230 Viper) = no PCMCIA unless jumpered down to 4MB.
Use Skick to kick down the Amiga to Kickstart 3.0
PCMCIA works without having to set the jumper to 4MB 
If the RAM is mapped into the Zorro II address space, it will not work with PCMCIA and 8MB. It doesn't matter what OS version you are running. It is a hardware problem, not a software one.
