mf.sys VaryingResourceMap support in Windows-2000

NTDEV
1

Hi Doron,

We need some help on mf.sys.

Standard resource maps can only assign an entire parent resource to a child
of a multifunction device, varying resource maps let you subdivide a parent
resource among children enumerated by mf.sys.

We are planning to develop a PCI Express Multi Serial add on card, in which
all the serial ports will be mapped to single BAR and a shared interrupt.
Windows XP and later version we can use the mf.sys services
(VaryingResourceMap, ResourceMap) to create child devices.

As per the Latest DDK documentation VaryingResourceMap supports Windows XP
and later version of NT operating systems. Is there any plan for Microsoft
giving the mf.sys (which supports VaryingResourceMap) in the next Windows
2000 service pack releases?

If not is there any way to get the windows XP mf.sys source code.

Thanks in advance

I doubt there will be changes to mf.sys for win2k. Support for win2k is ending, I don’t the know plans for any more service packs, bu there could be one planned. If you need this functionality, you should contact MSFT product support and see if they can open an incident for you.

good luck
