Hello, We have a little problem with a Computone Intelliport-8 serial board under Xenix 2.3. When the kernel tries to initialize this board, it is hung (the message is "D5"). The computer is a Olivetti M380/C (80386/16 Mhz). It doesn't matter what IRQ you use or which RAM area. The software installation gives no problem. All the other hardware seems to be ok. The strange part is that when we try to use the board with exactly the same kernel configuration on a M380/XP5 (80386/20 Mhz), everything goes right. Can somebody tell me what is going wrong? /* Rene Nieuwboer, Computersection Psychology, Vrije Universiteit, Amsterdam, Holland. Internet: reneni@psy.vu.nl */

I ran across something similar to this not too long ago. I don't recall the D5 message, but the system would just hang at initialization time. It turned out to be the way the motherboard wait states were set. Apparently the Intelliport board (unlike the Advantage board) has a problem with certain timings on certain motherboards. As I recall, I added a wait state to memory refresh and it started working. I say memory refresh, but it could also have been i/o waits -- sorry, I just don't remember exactly. --Bill
