Device Removable Bit Map (DRBM_0):
A 1 in a given bit position in this field
indicates that the corresponding downstream port of the RMH is connected to a non-
removable device. A 0 indicates that the port is exposed to the user. Bits 8:1 are
mapped to Ports 8:1. This bits control the value returned by the RMH in the
Deviceremovable field of the Hub Descriptor. A 1 in a given bit position in this register
will result in the corresponding bit in the DeviceRemovable field of the hub descriptor
being set to 1 as well (indicating that the port is connected to a non-removable device).
System BIOS is expected to set these values upon Boot and resume from Sx states.
