my sil 0680 raid controller with SiI0680A IDE BIOS (base Bios) for
converting it in a no-raid controller
My results:

Bios version 3.2.24 (version for RAID and NO RAID) with driver for
vista (downloaded from windows update):

Incorrect, BIOS version v3.2.24 is NOT for RAID - is disables RAID on cards
which do not have a jumper on the card that allows you to manually change
RAID/IDE compatibility.



F3 message(Press F3 to enter RAID utility) don't appear during boot ,

That is the expected behaviour for a NON-RAID controller. You have turned
your RAID controller into a standard IDE controller - so you won't get any
"F3" option. This is exactly what to expect as you flashed it with v3.2.24
NON-RAID firmware.

in Vista device manager the controller is installed but no access to
cd-dvd rom teac (it don't appear in my computer resources)

Bios vers 3.2.20 for raid controller and no vista driver (don't
available):
F3 message appear,in vista device manager, appear RAID controller but
with no driver available,teac dvdrom no available.

Bios vers 3.2.20 for IDE controller and Driver vers 1.2.26.0 by
SiliconImage:
NO RAID controller,in Vista device manager the controller is installed
but teac dvdrom no available in computer resources

Conclusion: with any bios and driver no optical disc available

I have tried to install XP drivers for RAID controller In Windows
Vista with my initial Bios but Computer freeze for updating

Can you help me?



Sorry, I've never used the IDE version of the card, or the IDE only drivers.
