It's an Asus P5G41T-M LX & the manual says : "This motherboard supports Windows Vista/XP/7 OS". The previous mobo (Asus P5K-VM) has a menu Main -> IDE Configuration -> Configure SATA as [IDE] with an option 'AHCI', which was enabled & the kernel booted properly; its manual says "If you want to use the SATA drives as parallel ATA physical storage, keep the default setting [IDE]", but that caused the same problem that the kernel couldn't find the drive; when I configured it as [AHCI], everything worked (since 2007). The new manual has a menu Main -> Storage Configuration -> ATA/IDE configuration [Enhanced] which corresponds to a menu 'SATA configuration' in the old manual & [Enhanced] opens another item 'Enhanced mode support on S-ATA', which allows you to set Serial/Parallel/Both for ATA. Since Ubuntu, Mandriva & System Rescue boot without any problem & SR does find my LVM partitions & can mount them properly, there must be settings which allow the kernel to find the HD with this mobo. I will look them up & compare them all later today, but any further advice is very welcome. Thanks so far. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
