Hi,
based upon discussion with Andy few days ago, when testing patches
to fix multiport serial card fixes + brainboxes 4100 detection support
I created experimental patch to add another brainboxes card detection
(this one has 4 serial ports, no parport, so I added it to 8250_pci.c)
here's lspci output:

manual card setup is possible as follows:
/bin/setserial /dev/ttyS2 port 0xE880 irq 11 spd_normal skip_test autoconfig
/bin/setserial /dev/ttyS3 port 0xE888 irq 11 spd_normal skip_test autoconfig
/bin/setserial /dev/ttyS4 port 0xE890 irq 11 spd_normal skip_test autoconfig
/bin/setserial /dev/ttyS5 port 0xE898 irq 11 spd_normal skip_test autoconfig
here's my patch:

the problem is, it doesn't work. One thing I'm not sure and I'd like to
ask is how do I find out which FL_BASE value should I use? I tried FL_BASE0
and FL_BASE2, but instead of trying all possible values, I though it'd be better
to actually KNOW what should go there and why..
One more thing to note, the card only works for me (using setserial manual
setup) when I disable APIC.. this is probably worth some investigation as well..
If somebody would give me some guidance, I'd be grateful
thanks!
