"CMos checksum bad. Overclocking failed."
But I was not overclocking, I used the deafult Bios settings.
When I then boot up WindowsXP, new hardware is found: secondary IDE channel. But this driver cannot be installed. In Windows hardware manager I find 2 primary IDE channels and 2 secondary IDE
channels (one with yellow exclamation mark).
When I go back to previous Bios version 6.005 I still get the bad checksum messsage, but no new hardware found and there is only 1 secondary IDE channel, and no exclamation mark.
