This is a little complicated.
I have a Via ACHI/SATA 4 port onboard controller
Original set up was with ata 133 western digital 80gb.....installs and everything worked great no matter what.
Then I installed my first SATA 3.0 drive.....Seagate Barracuda 500gb
In Bios 1st primary ata 80gb, 2nd primary ata cd/dvd burner, third primary Seagate 500gb Sata
To get the most out of my new drive I wanted to do fresh install of hardy 8.04
Installed xp pro sp3 from dvd image....boots fine...udma6 listed in device manager instead of SATA 3.0 but after testing drive my throughput was 82mb and after some research it seemed like this was what I could expect from Sata 3
my ata 133 80gb tested at 51mb so this seemed ok to me.....at this point my southbridge bios was set to SATA
Try unetbootin hardy 8.04 64bit.....failed to see my sata drive
Try live cd suse 11rc1 install.....failed to see my sata drive
Try dvd install suse 11rc1....failed to see my sata drive
Try Mint 4.0 live cd install.....no problems....mint running well...install program recognized SATA as SCSI...I researched and found this was normal for some installs
Removed ata 133 80gb from system.....tried every install again....only Mint 4.0 installs all other installs say I have no hdd
Go back to bios change southbridge SATA to ACHI and I enable SATA from rom
Try all installs again.....says no hdd
Also try unetbootin Mandriva install....installer loads Via ACHI/SATA drivers.....then says I have no hdd
Try fresh install of Mint 4.0 with live cd and new bios settings.....my sata is now listed as 1st primary......Mint 4.0 installs perfectly and new bios settings seem to make a difference because now mint boots very fast.
Ok now I download Mint 5.0 beta 48......live CD stops at initramfs.....no problem i try again with compatability mode....now I can see litsting of whats going on.
Live Cd in compatability mode stops at initramfs as before but does not hang and keeps loading. When it gets to my sata drive it says drive one not seen...then it trys to load some sort of sata 3.0 driver then hangs and says drive not seen....it keeps repeating this process every 5 seconds until I turn off computer.
Any help would be appreciated...I know is long post....thanks for your patience
