Hello VI,
Long story short, it's a nice board with a Core i5 4gig ram. On board video. But it hates SATA drives.
The default setting in the BIOS for "SATA mode" is "IDE mode"
This wont allow either LXDE.2011.06 or the 64bit test3.iso to boot. It drops the boot device and craps out deep into the boot sequence.
So I can boot with a liveusb. But the ATA drives don't show up. And I can't burn a CD.
Changing BIOS SATA mode to "AHCI mode" allows the drives to be seen but switching on and off hot-swappable mode seems inconstant and system feels unreliable.
of course, it should be set to AHCI... what do you mean by "switching on and off hot swappable mode" ? is this a BIOS settings ?
Found a configuration that allowed installation to a 1TB seagate, and it booted, but had lots of backchat in the bootup.
the best thing you can do here is to provide some more info

, i.e. while running liveCD:
dmesg | grep ata
fdisk -l
Inserting an old PCI card with two sata ports appears to alleviate all this madness by not using the Mobo's SATA ports. The MOBO, otherwise, works fine from a liveusb (my first try with the new board). Only when I started adding drives it went haywire. Wondering if the on board SATA chip is still a little bit new?
Will look into updating BIOS firmware also...
Any thoughts?
if your MB is this one:
http://www.asus.com/Motherboards/Intel_Socket_1155/P8H61M_LEit appear to support some fancy BIOS settings UEFI, EZ mode, Advanced mode .... very probably you need to tune up some BIOS parameter ....
