VIA SERIAL ATA RAID CONTROLLER DRIVER

 1. In BIOS, what does “SATA Controller” with the ability to select either IDE
    or RAID mean? Ask Question 5. *2 x UltraDMA 133/100/66/33 *2 x Serial ATA

    ATA interface, and an optimal solution for RAID. SATA hard drives deliver
    blistering transfer speeds of up to 150MB/sec. HP 4-channel SATA RAID PCI
    Controller supports cables that are up to one meter long and substantially
    thinner, eliminating cable-routing problems and increasing air circulation.

Enter the code shown in the picture on the next page. I hit F6 and then
installed the first drivers, I selected the whole partition thing and formatted.
And after it formatted it asks me install the the VIA Serial ATA RAID Controller
Drivers. I didn't think you needed 2 floppies for an install.

In my BIOS, I've got a setting called 'SATA Controller' that can select either
IDE or RAID.

It's currently set to IDE.

What does this setting mean, and will bad things happen if I change it?

My motherboard is an Asus P5VD2-MX if that helps.

tl;dr:

What does this setting [SATA controller mode = IDE] mean?

In this BIOS setting, 'IDE' means separate disks attached to the main disk
controller will each be shown as one separate disk to the operating system (for
example as C: and D:).

will bad things happen if I change it?

Bad things will happen if you change controller mode from IDE to RAID. Backup
your data first.

Bad things will probably happen if you change controller mode from IDE to RAID.
Unless you first back up your data, then reconfigure BIOS, connect up
appropriate drives to appropriate connectors, configure RAID, reinstall OS and
restore data.

The spec and manualsays

'UltraDMA 133/100/66/33' means Parallel ATA (PATA) historically known as just
'IDE'.

So you have two controllers, each of which controls two SATA connectors. The
main controller also controls two IDE connectors. Each of the IDE connectors
supports up to two devices.

The BIOS description is 'SATA controller mode: [IDE] or [RAID]':

My initial guess was that 'IDE' refers to a pair of internal PATA (IDE)
connector for the VIA 8237A controller and that 'RAID' refers to a pair of
internal SATA connectors for the same controller. In that case You could
probably only be using one or the other pair of connectors at a time.

I now suspect that

 * by 'SATA Controller' they mean the VIA 8237A controller (which the spec
   implies also controls the PATA channels)
 * by IDE they mean non-RAID - the OS sees each drive as a distinct drive (e.g.
   C: D: etc)
 * RAID means you get to choose (elsewhere) between RAID0, RAID1 and JBOD.
 * the 'JBOD' in the spec probably means 'concatenation, where all the physical
   disks are concatenated and presented as a single disk.'

ASUS'/Phoenix's choice of words to describe this in the BIOS is not as clear as
it should be.

For some reason, no one has mentioned the obvious differences between IDE and
RAID (AHCI). IDE is a software EMULATION mode that allows operating systems that
don't natively support AHCI (Advanced Host Controller Interface) and SATA to
still be able to detect and use your drives as if they were connected to an IDE
controller.

This, of course, means that you lose the additional functionality provided by
AHCI (RAID is AHCI-compatible), such as NCQ (native command queuing),
hot-swapping, etc.

For maximum performance, you should always put your SATA controller in AHCI or
RAID mode. Please note that you cannot easily make this change AFTER installing
the operating system. It is best to enable it and then install the OS.

Put simply, no you cannot change the bios setting once the OS is installed, or
it will bluescreen on you. IDE mode on that particular board is for when you do
not have more than one hard drive and have no need for Raid.

This setting must be set prior to installing the OS, its a decision you make
before you install, I guess you can just say IDE is Non-Raid on that
motherboard.

MoabMoab

To clarify the answer from @RedGrittyBrick - changing the mode from IDE to RAID
will very likely cause problems. The reason for this is simple - your OS expects
a given driver to work with the installed hardware. When you change this BIOS
setting the way the OS interprets the hardware changes and it very likely will
result in a BSOD.

That being said there are certain interchangeable settings from the OS's
perspective. As long as the drive is presented in the same fashion the OS does
not care. When I first received my new laptop (a Dell E6420) I had an existing
eSATA enclosure I wished to use with it. Even if you do blue screen your system
a few times you should be able to restore access by resetting your settings to
their current configuration.

It is theoretically possible to inject the correct drivers in the case of a blue
screen on the BIOS change as well.. I never spent the time to get that to work
however.

I think some simple definitions may help clarify things.

RAID - Redundant Array of Independent Disks. Basically, this is where you have
two or more hard drives acting as one single hard drive. This is desirable in
systems where the possibility of loosing data at any one instance is critical
and/or where an overall better r/w speed is desirable. But just enabling RAID in
the BIOS is only the first step to obtaining a true RAID system. You still need
to do other things like 'stripe' each drive (meaning format and loose whatever
is on them) in order to properly configure a RAID system.

SATA - Serial ATA, or Serial Advanced Technology Attachment. SATA and PATA are
both IDE interfaces only SATA is faster than PATA (which some people say is
contrary to electronic theory since parallel connections should be faster). So
if you only have one hard drive you might as well leave the BIOS alone and set
it to IDE. But really, it doesn't matter. That is, unless/until you
format/prepare your drive(s).

Now if you do want to get better performance from your hard drives, you probably
should be looking at installing or updating better chipset drivers and/or
adjusting your drive controller properties to allow DMA (Direct Memory Access).
That's usually done for you in Windows. But I digress. Hopefully, that answers
it.
