Is there a mechanism to mark a driver as *boot* ? How does windows
find out the order to load drivers in a particular catagory, can some
one tell me the registry key for this. I am talking about class
drivers and not filters.
Thanks

Read the DDK see “Specifying Driver Load Order”

You set the start type of the service for the driver to boot when you
create the service.

Load order for boot type drivers is like load order for any other type
of driver.
For a PNP filter driver you don’t generally need to be concerned about
load order.
Unlike NT 4 where the order you got attached to the stack was controlled
by your load order, today it’s controlled by the PNP system (using the
UpperFilters and LowerFilters lists in the device node). No matter what
order atapi.sys, disk.sys and your driver load in, PNP will call their
AddDevice routines in the correct order to build the stack.
That said - since you’re making a driver that may load in the boot disk
stack, you need to have a StartType of Boot (0). If you don’t the
system won’t be able to boot (you’ll get an 0x7b bugcheck) - the problem
is that PNP can’t start a device until all the drivers are loaded, and
it can’t load your driver if the disk stack isn’t running. Making your
filter a boot driver ensures it’s read into memory by ntldr and so you
won’t have this problem.

Search MSDN for “driver load order”, there was a description there.
