Do I need a miniport driver?

NTDEV
1

Hi,

I have an ISA card that has a specific I/O range. I can simply
read from and write to the port range from 95/98/me. With Windows 2000
and XP do I need to write a miniport driver that can do the I/O on my
behave?

Are there some less complex examples besides the DDK?

Thanks in advance,

Bruce

You would only need a miniport driver if this card supported network or scsi
bus devices. You do need a kernel mode driver to access the device IO
registers in NT, as NT is a real operating system, unlike windos9x/Me. There
are commercial products (windriver) that you can buy to make this relatively
painless and give you a user mode interface, or you can just write a simple
nt device driver - if this is an ISA device you could get away with a NT4
style non-pnp driver.
