Hi Niels,
I don't really know why but the output of dmesg only shows my oboard
serial. I have looked all over the dmesg and i cannot find the device
even at an unknown state
I have even checked dmesg log for the matter.
These are discovered for the onboard serial ports.
kernel: serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
kernel: serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
kernel: 00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
kernel: 00:0d: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
I will try and remove the card to read what it says exactly on the chip
and update the email. Its definitely ITE but i will give u exactly what
it says on chip.
