@Ilwrath:
A graphics card will not use space from the motherboardmemory-area of an A4000.
The A4000 will map ZorroIII cards somewhere in the address-space 0x10000000 to 0x80000000 which is reserved for ZorroIII-cards whilst the motherboard memory is configured somewhere in the address-space 0x01000000 to 0x08000000 which is reserved for motherboard resources so they wont use space from eachother
.
If the computer was an A2000 which has 24-bit addressing a graphics card would limit the maximal amount of Fast-RAM. The CV64/3D should for example limit the maximum Fast-RAM from 8MB to 4MB if it doesnt use any memorybank-switching or similar technique.
