Initially I switched all IDE related services and drivers to Start=0 in ControlSet001 assuming PC will use it at boot, but it didn't. Then I followed with CurrentControlSet, and it did. Is my assumption correct that CurrentControlSet is remembered at reboot as ControlSet001 or as LastKnownGoodConfig? So next boot the OS uses ControlSet001 or LastKnownGoodConfig?
I ask because when OS is offline, there is no CurrentControlSet in its Registry, so its deleted at shut down?

Last time I checked, Select was set to 1. I fixed CS001 to pciide Start=0, and OS didn't boot. According to your posts, when OS was exited, CCS was saved at CS001, meaning pciide Start=3. But when it failed to boot in IDE mode, and I booted in SATA and looked again, CS001 was still with pciide Start=0, and CCS was with Start=3. How is that possible?

From the Wikipedia link I gave and you didn't follow...
Multiple control sets (typically two) are kept, in the event that the settings contained in the currently-used one prohibit the system from booting. HKEY_LOCAL_MACHINE\System contains control sets labeled ControlSet001, ControlSet002, etc., as well as CurrentControlSet. During regular operation, Windows uses CurrentControlSet to read and write information. CurrentControlSet is a reference to one of the control sets stored in the registry. Windows picks the "real" control set being used based on the values set in the HKLM\SYSTEM\Select registry key:
* Default will be the boot loader's choice if nothing else overrides this
* If the value of the Failed key matches Default, then the boot loader displays an error message, indicating that the last boot failed, and gives the user the option to try booting anyway, or to use the "Last Known Good Configuration".
* If the user choose (or has chosen) Last Known Good Configuration, the control set indicated by the LastKnownGood key is used instead of Default.
When a control set is chosen, the Current key gets set accordingly.
