So one leader of our IT, who is a Windows expert, suggested we can use
int 13h and I/O in Linux. But int 13h just is used in real mode.
Can you give me some advice to persuade him? If it is feasible, can you
introduce me?
int13 is real mode only, runs polled and 16bit with one command at a
time. As far as I know even Windows no longer uses it for anything but
booting.
Even can you give some good solutions to solve the compatibility problem?
For hardware where we have info the right answer is to report bugs and
get them fixed (or indeed send fixes). For the more general case the
ata_generic driver will drive anything that is SFF8038i compliant and you
can just add PCI identifiers to it for anything you hit.
I am working on a generic ACPI driver to go with it for such cases.

Thank you for your help and explanations.
I will do some research work on ata_generic driver. Can you give me some
advice or related information to do deeper research?
I alse found the problem of ACPI in our product, so we turn it off, but
always caused some other problems. So i think a generic ACPI driver will
be welcome.
And your mail is the best message received today before going home.
