ICE / EVA board related

Even if I start IPI.EXE, "NO INTERFACE BOARD" is displayed and I cannot use it at all.

Q)

I inserted the PC interface board into the ISA bus to connect the Hitachi ICE (E7000 / E7000PC) and EVA boards, but when I started IPI.EXE, "NO INTERFACE BOARD" was displayed and it was completely usable. not. Could I ask the reason?

A)

Communication between (E7000 / E7000PC / EVA board) and the interface software is performed via 16K bytes in the main memory space as shared memory.
In many IBM-PC / AT compatibles, the factory setting prohibits the use of this area as shared memory.
From the menu named SHARED MEMORY or SHADOW MEMORY from the BIOS setup, change the same area as the address set by DIP SW on the PC interface board to the Enable setting. Be sure to change the DOS environment variable E7000SYS on the host PC as well.
