differences in the entry: Description
MCS9805, MCS9815, MCS9820, MCS9835 and MCS9845 PCI Serial / Parallel ports on Linux platform.
[p]
Specific options must sometimes be passed to the parport_pc driver using modprobe in order for the card to work properly. See the following PDF for detailed instructions: [a]http://www.asix.com.tw/FrootAttach/driver/MCS98xx_Linux_Driver_Installation_Guide_v100.pdf[/a]

To get this driver working I needed to get port addresses using lspci
[/p]
[code]
#lspci -v
04:04.0 Communication controller: MosChip Semiconductor Technology Ltd. PCI 9815 Multi-I/O Controller (rev 01)
Subsystem: LSI Logic / Symbios Logic 2P0S (2 port parallel adaptor)
Flags: medium devsel, IRQ 7
I/O ports at c050 [size=8]
I/O ports at c040 [size=8]
I/O ports at c030 [size=8]
I/O ports at c020 [size=8]
I/O ports at c010 [size=8]
I/O ports at c000 [size=16]
Kernel modules: parport_pc
[/code]
I then made a file inside /etc/modprobe.d that passed passes specific addresses into the driver at each boot
[code]
/etc/modprobe.d/01-MCS98XX.CONF:
#
# Special settings for the MCS98xx parallel driver to work correctly
