Allocates and maps the base V86 memory for a virtual machine. Uses EAX, Flags.

• Returns with the carry flag clear if successful, or set otherwise. If the service succeeds, the actual number of pages allocated and mapped to the VM is returned in the EAX register. This value does not include the space from zero to the first VM page.

VMHandle

Handle of the VM.

DesiredSize and MinimumSize

Desired size and minimum size of the VM address space, in kilobytes. These sizes include the address range from zero through the first VM page.

Flags

Memory attributes for the VM. Can be zero or this flag:

AV86PLocked (bit number AV86PLockedBit)

Specifies that the VM memory is to be always locked, regardless of the pager type or whether the VM is suspended.

If an error occurs, this service calls the GetSetDetailedVMError service to set an error value.
