    Hello friends!

    I have the following problem:

    I have:
    00:0c.0 Serial controller: NetMos Technology 222N-2 I/O Card (2S+1P) (rev 01) (prog-if 02 [16550])
            Subsystem: LSI Logic / Symbios Logic: Unknown device 0012
            Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
            Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
            Interrupt: pin A routed to IRQ 12
            Region 0: I/O ports at b800 [size=8]
            Region 1: I/O ports at bc00 [size=8]
            Region 2: I/O ports at c000 [size=8]
            Region 3: I/O ports at c400 [size=8]
            Region 4: I/O ports at c800 [size=8]
            Region 5: I/O ports at cc00 [size=16]

    I have:
    options parport_pc irq=7,none dma=3,none io=0x0378,0xc400 io_hi=0x0778,0
    options lp parport=1

    It was all working.

    The serial port where here:
            /dev/ttyS2, UART: 16550A, Port: 0xbc00, IRQ: 5
            /dev/ttyS3, UART: 16550A, Port: 0xc000, IRQ: 5

    Then I took out a networking card and the IRQ of the NetMos card changed
    to 12 (see above, before it was 5).

    Now the serial ports are:
            /dev/ttyS2, UART: 16550A, Port: 0xbc00, IRQ: 12
            /dev/ttyS3, UART: 16550A, Port: 0xc000, IRQ: 12
    and working. But when I load the parport(_pc) modules with the above
    parameters I get this in the syslog:

    parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,ECP,DMA]
    parport 0xc400 (WARNING): CTR: wrote 0x0c, read 0x0d
    parport 0xc400 (WARNING): DATA: wrote 0xaa, read 0x00
    parport 0xc400: You gave this address, but there is probably no parallel port there!
    parport1: PC-style at 0xc400 [PCSPP,TRISTATE,EPP]

    Can you tell me where my parport is lost?

    Thanks a lot for any hint and tips!

    I am using debian/sid, linux-2.4.22-pre7.

    Best wishes

    Norbert
