Linux driver for ITE887X serial and parport:
Test in Mandrake 9.0 ,and update kernel to 2.4.20
Warning:
This driver only for Linux kernel 2.4.19 or 2.4.20.
If your kernel is older, please update to 2.4.20 .
"/usr/src/linux" is the default kernel path.
If you use redhat , the path is "/usr/src/linux-2.4".
If you do not know how to compile kernel, please
read kernel-howto document for reference.
Conver the two files "serial.c" and "parport_pc.c":
( Note: please backup the two files first! )
In kernel 2.4.19:
#cp serial_19.c /usr/src/linux/drivers/char/serial.c
#cp parport_pc_19.c /usr/src/linux/drivers/parport/parport_pc.c
In kernel 2.4.20:
#cp serial_20.c /usr/src/linux/drivers/char/serial.c
#cp parport_pc_20.c /usr/src/linux/drivers/parport/parport_pc.c
Compile kernel:
#cd /usr/src/linux
#make menuconfig
select the options:
Warning: "Parallel port support" must be "M", because
the 887X serial must be load befor parport.

Parallel port support
<M>Parallel port support
<M> PC-style hardware
< > Multi-IO cards
[*] Use FIFO/DMA if available
