The Chip A type is a dual SCC serial line UART chip, chip B/C named AURORA look like FIFOs (don't know them), and chip D is a 10MHZ 80186 microcontroller (with DMA and Timer on chip). But unless it emulates the common 8250/16450 chips to the I/O ports, which I doubt, given the source of this board, you are quite out of luck to make this run with 386bsd. Perhaps Sun is so kind to give out specifications of this no longer produced board. At least some quickly and unauthorized information from the Sun man pages and header files (Copyright Sun Microsystems): CONFIG - Sun386i SYSTEM device zs0 at obmem ? csr 0xFC000000 flags 3 irq 9 priority 6 device zs1 at obmem ? csr 0xA0000020 flags 0x103 irq 9 priority 6 Looks like a memory mapped device, rather than I/O mapped. Furthermore, I found the following files on my Sparc which could be helpful to analyze the behavior: /sys/sundev/zscom.h /sys/sundev/zsreg.h /sys/sundev/zsvar.h /sys/sundev/zs_proto.c /sys/sundev/zs_conf.c Unfortunately these are too large to post, and furthermore the Copyright might prevent this. Find a Sun where you can copy them. Hope this helps first.
