writing PCI 1724 driver in 2.6 kernel

[babu]

I am presently having PCI 1724 card 2.4 kernel driver . I want to
write driver for it in 2.6 kernel.For that i have taken adv_pci1710.c
file in comedi distribution and changed device id ,vendor id and
iorange details in that file like this below.
{"pci1720", 0x1724,
IORANGE_1720, 0, TYPE_PCI1720,
0, 0, 32, 0, 0, 0, 0x0000, 0x3fff,
NULL, NULL, &range_pci1720,
0, 0},
After that i inserted the module,i observed that it is detecting the
board and also giving board detials also.Now i want to write analog
output function in normal mode using control register.Can anybody help
me out how to proceed to achieve this task

For Advantech PCI 1724 AO card, the only clue I could find for normal
mode, was the function "pci171x_ao_mode0" in the file pci1710.c
present in the Advantech own distribution (comedi-0.7.60).
What if you start with adv_pci1723.c instead of adv_pci1710.c for the
1724 - 2.6 kernel driver?
