The north bridge of AMD (751/761) with, we have become the setting, bit18 of offset 60-63h of the host bridge Halt Disconnect Enable, when here is designated as 1, separating is possible. By the way, bit17 with Stop Grant Disconnect Enable, with CoolON makes both 1.

In case of KT133 type when bit7 of register 52h with Disconnect Enable When STPGNT Detected, designates here as 1, separating can do with the north bridge of VIA. With KT266 system 92h is used in place of 52h, it is necessary furthermore for Disconnect Enable When Halt Detected to be added by bit1 of 95h, to make both 1. With KT400 system, 92h/95h is modified to D2h/D5h. Furthermore, because can be moving KT880 to the register 82h/85h of function.

With the north bridge of SiS, 730 systems 6Bh, 735-745 6Ah, after of the 746 bit0 of 6Ch C1 (Halt) has become Disconnect. With SiS735 bit3 of 6Ah S1 (StopGrant) is information, Disconnect, but here seems that usually becomes effective.

It is detailed unclear, concerning the north bridge of nVidia, but as for nForce it seems that when in 11b, with nForce2 bit7-4 of 6Fh is designated as 0001b, separating can do bit3-2 of E7h.

Takže zde je uvedeno bit0 registr 6C umožní přechod do C1 tedy hlat stavu..., takže ten Rx6C Bit0 nastav na enable - 1
