No it was pretty straughforward with the Si3114 With the nvidia controller
I thought you needed the raid enabled. It turns out that you want raid
disabled if you want the nvidia controller to treaat each disk as a
separate drive. Spent three days figuring that one out.
And can you confirm that in the JBOD
With Si3114 they are single disks acting separately I believe its called

Leadfoot, have you been able to set up disks individually ?
There are some threads where people claim to have trouble with this.

The claim is, that at one point the A8N-SLI had an option to set the
SIL3114 to IDE mode, versus RAID mode. I don't see that option in
the manual, so perhaps it was only in early versions of the
actual BIOS ?
You cannot download a datasheet for the SIL3114, but for the
SIL3112 I did get a datasheet. On that chip, there is a pin
called "IDE_CFG", used for IDE-RAID config.
"When PCI_RST_N is deasserted, this pin is an output and represents
flash memory address bit 0. During reset, it is sampled to configure
Mass Storage class or RAID mode in the PCI Class Code register. A
high on this pin sets Mass Storage class, a low sets RAID mode. The
configuration state is latched internally when PCI_RST_N is
deasserted. This pad is internally pulled high to enable Mass
Storage class if left unconnected."
Now, _if_ that pin existed on the SIL3114, it could be driven by a
GPIO on the motherboard, under BIOS control. Or, it could be set
permanently to RAID mode. In any case, if people are having trouble
installing the "vanilla" IDE driver for the SIL3114, this might
be the reason. If the IDE driver is installed, and that pin is
sampled in RAID mode, then the enumeration of the 3114 would
indicate "RAID mode", and the installer could not work.
In RAID mode, the options I could see are: setting a single disk
to a RAID 0 stripe of one disk, or using JBOD. I thought one
of the side effects of using JBOD, was an OS like WinXP might
deal with the disk in "dynamic disk" mode, and for some third
party tools, this can cause problems.
So, there appear to be a few unanswered questions about SIL3114
on A8N-SLI, such as whether it ever really supported the
vanilla IDE driver, and why Asus would remove it, if the
ability to do that was present. Since there is only one
motherboard BIOS module available for SIL3114, that module
would have to deal with such a pin in both states, so that
should not be an issue. (And, BTW, _all_ the BIOS files I
checked for A8N-SLI Deluxe have the same 5139.bin module to
control the SIL3114 chip in the BIOS. That has never been
updated apparently, but neither do I see changing that
making any difference.)
Without a datasheet for the SIL3114, I cannot be 100% certain that
the same kind of pin exists, but architecturally, the SIL3114 is
just two SIL3112 chips slapped together. So the same pin
should exist somewhere on the chip. The SIL3114 has more pins than
the SIl3112, so it is not possible to guess at which pin it is.
