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.
