Hi.

there is too many IDE interfacing schematics and free
projects on web, but you should note that all IDE
devices use a common command set known as ATA
standard, which is accessible on net.

you should send commands to IDE device and get answer
back of it. at the other hand, there is a hidden
sector in IDE controller's memory area which contains
all needed information about HDD/CDROM including # of
heads and cylinders and sectors/track.

by know, I dont remember where u can find stuff you
want, but if it's an emergency I can try to find it in
my download archive. but all versions that I remember
uses AVR micros. but if you want to do so with '51
family or by IBM-PC is to convert the code on your
own.

for connecting directly to IDE via PC port, you need
to have a PPI port or something like that.

good luck.
reza.
