I've configured it based on the following information : IRQ 9 (2 according to the silkscreen) "enhanced" mode (this seems correct - I can see the UARTs with Debug) Base addresses 0x180/1a0/280/2a0 (again they appear here with Debug) Interrupt sharing disabled (sw3 off - no way to verify this) sw4 is off - I have no details on this. My kernel config looks like this : device sio2 at isa? port 0x1a0 tty irq 9 flags 0x201 vector siointr device sio3 at isa? port 0x1a8 tty flags 0x201 device sio4 at isa? port 0x1b0 tty flags 0x201 device sio5 at isa? port 0x1b8 tty flags 0x201 If my understanding of things is correct, that should work. At startup, I don't get any diagnostics : sio2 not found at 0x1a0 sio3 not found at 0x1a8 sio4 not found at 0x1b0 sio5 not found at 0x1b8 I have COM_MULTIPORT defined (no quotes, tried it with as well), and am generally stumped. I've studied a number of working configs (none using the same board though) to no avail. Any suggestions? Anyone else using one of these boards? (If the board is toast, I can replace most of it, though the PALs may be a shade tricky, I can replace them if I can get a good fusemap...)
