I finally got the solution from APSoft themselves and posted in in the eCS newsgroups. Here it is:

In order to support CardBus PC Card adapters and CardBus cards CardWare uses memory outside of the first GB of memory address space.

In order to access CardBus and ExCA registers of the socket adapter CardWare tries to allocated 4kB of memory for each socket. By default SSPCIC search any empty 4 KB of memory between 0x40000000 and 0x60000000 (i.e. 1GB and 1.5GB). If your computer has 1.5 GB of RAM or more you will need to shift this area to unused address space. You can change above limits via /RS and /RE parameters of SSPCIC. E.g. /RS:0x50000000 /RE:0xA0000000.

In order to configure the CardBus card Card Services will search the free memory between 0x40000000 - 0x80000000 (i.e. 1GB and 2GB). If your computer has 2.0 GB of RAM or more you will need to shift this area to unused address space. You can change above limits via /RS and /RE parameters of PCCS. E.g. /RS:0xA0000000 /RE:0xC0000000.

Ignore previous posting, read this:
