Using BIOS interrupts in a Embedded system

NTDEV
1

Hi all,

I am facing to develop a driver that manage a static-RAM bancks on a
embedded system with
Windows XPE.
I already made other types of drivers under NT4 , but i’m a newbi for this
platform and
kind of problem.

This device has two bancks of static-RAM (0x0D0000::0x0DFFFF) and its BIOS
perform
3 functions via INT 52H for READ, WRITE and VERIFY data on it.

I’ m a bit confuse on how to manage these capabilities from my driver.
Which HAL’ functions are recomanded for use these BIOS functs ?
Or, are there other better methods ?

Somebody knows where is possible consulting samples or documentation ?

Any suggestion are very appreciated.

Thanks in advance.

With kind regards.

Do you want to use this RAM as usual RAM for the rest of the system or for some special purpose?
If first - then sorry, BIOS+hardware support is the only way.

Max,
Is the second way, this RAM will be used for store special infos about the
system, not for
other purposes.

Thanks a lot.

Then map it to PCI config space BARs and access as PCI device.
