General Information

#TBD: Find board HP product number

The SuperIO is the emulation of HP9000 PCI expansion card containing PC style peripherals:

• parallel port
• 2 serial ports
• dual-channel IDE controller
• floppy disk controller
• USB 1.1 controller
• timer
• PIC interrupt controller

 The current version of Charon-HPA emulates only a subset of these devices.

Currently supported are (depending on support by the emulated model and guest operating system)

• two serial ports
• one parallel port

SuperIO Module Configuration

Before any devices of the module can be configured  and used, the module must be loaded in the emulator configuration file.

SuperIO module can be loaded to any system model supporting PCI bus. By default it is loaded on models based on the Astro chipset (rp24xx and rp54xx).

Use the following syntax to load this module:

load SUPERIO sio <bus-number> <slot-number>

Example:

load SUPERIO sio 0 6

Serial ports installed on SuperIO module can be configured the same as other serial ports. Please see chapter Serial Line Emulation Notes for more information.

Path names for serial devices in the emulator configuration:

• superio_001.uart0 - COM0 port
• superio_001.uart0 - COM1 port

Serial ports configuration example:

superio_001.uart0.device.type="telnet"
superio_001.uart0.device.port=":30001"

superio_001.uart1.device.type="telnet"
superio_001.uart1.device.port=":30002"

Parallel port installed on SuperIO module connects to the host system parallel port device /dev/parport0, so the parallel port output from guest OS is redirected to the host parallel port. No additional configuration for the parallel port is required.

If no parallel port device exists on the host system, error message printed to the emulator log. It does not affect system operation, only parallel port redirection is not working:

err:open('/dev/parport0', O_RDWR) is failed (errno 2) No such file or directory
err:ioctl(handle, PPCLAIM) is failed (errno 9) Bad file descriptor

Modern host systems has no physical parallel port installed. USB-LPT adapter or software redirector (like LPT-over-IP) can be used. Emulated parallel port operation depends on host parallel port operation, some USB-LPT adapters works not stable.

After booting the guest HP-UX system, this will result in an ioscan output similar to the following:

ba          1  0/0/6/1      superio   CLAIMED     BUS_NEXUS    PCI Core I/O Adapter
tty         1  0/0/6/1/1    asio0     CLAIMED     INTERFACE    Built-in RS-232C
tty         2  0/0/6/1/2    asio0     CLAIMED     INTERFACE    Built-in RS-232C
ext_bus     4  0/0/6/1/3    SCentIf   CLAIMED     INTERFACE    Built-in Parallel Interface
unknown    -1  0/0/6/1/4              UNCLAIMED   UNKNOWN      Built-in Floppy Drive

However, it may be necessary to install the required kernel drivers in HP-UX and rebuild the kernel to activate the interface.

If the ioscan command shows the parallel port as UNCLAIMED, perform the following steps:

1. Use the kcmodule command to verify the status of the required drivers:
   # kcmodule |grep CentIf
CentIf static explicit
SCentIf static explicit


2. If the status is unused, load the modules into the kernel using the commands:
   # kcmodule CentIf=best
# kcmodule SCentIf=best


3. You will be informed that this change can only become active after the next reboot. If you confirm, the kernel will be modified and you can reboot the system.

Once the ioscan command shows that the parallel port as CLAIMED by the correct driver, you can, for example, use SAM to configure a printer on the parallel port
(Printers and Plotters > LP Spooler > Printers and Plotters > Action > Add Local Printer > Add Parallel Printer).
