Yes, there's a trick ;-( Here's how it works:
There's three methods for finding serial ports that apply to rx2600
w/ECI card. First, we parse the HCDP table. Second, we search the ACPI
namespace for serial ports. Third, we walk the PCI busses looking for
The two built-in serial ports are in the ACPI namespace, the ECI card
actually contains a PCI bus where we find the serial ports. Firmware
determines which port is listed in the HCDP table according to which
Console Input & Console Output devices were listed first. Unfortunately,
you can't tell which one was selected first, so the safe thing to do is
make sure only one is listed.

Yes, after upgrading your firmware, you have to restore your ConIn/ConOut
to sane values.

Mmm.. not exactly. In the instance you quote here, ttyS3 would be
the mirrored port. ttyS4 and ttyS5 are the local and remote sessions
Of course, it should be:
ttyS0 mirrored console
ttyS1 serial A
ttyS2 serial B
ttyS4 local session
ttyS5 remote session
once you fix your ConIn/ConOut settings.
