The factory enables INT13 by default, so the following sequence is what I would recommend, having previously installed 2 of these 2720SGL cards:

(1) boot into the card’s BIOS with CTRL-H;

(2) initialize all member SSDs;

(3) create a RAID-0 array with 2 x SSDs as members;

(4) re-boot into your motherboard BIOS and
choose this RAID array in your Boot Priority;

(a) Highpoint recommends that all other storage
devices be disconnected from the motherboard’s ports,
temporary: see README.TXT for further details;

(5) proceed to do fresh install of Windows,
from your Windows Setup disc.

(The above sequence is obviously for a fresh install sequence.)

If you already have an OS installed on other storage media,
you can try the following:

(6) download the latest device driver and bios for the card
from Highpoint’s website;

(7) install the card, but do NOT connect any cables or
storage devices;

(8) load the device driver when requested to do so;

(9) flash the card’s latest bios, using the Windows program
that you downloaded with the bios;

(10) here, you need to decide whether to DISABLE INT13 or not;
if you do NOT intend to boot from this card, then you should
DISABLE INT13 when you flash the latest bios.

I haven’t tried restoring an OS drive image to the 2720SGL,
which requires that you ENABLE INT13, to boot from this card
(i.e. leave the factory default unchanged).

Don’t forget to review README.TXT which explains
when to disconnect all other storage devices.

Hope this helps.

The device mapping order in system is same as BIOS setting utility. The disk

mind when installing Windows, otherwise OS may be installed to wrong location.

5. Known Problems
==================

* Install OS to devices attached to RocketRAID 272x/271x SAS controller

Before installing OS to devices attached to RocketRAID controller, you
must remove the drives connected to other controllers from your system
temporarily. After OS installation complete, you can put them back.

* Moving disks to other controllers

When you want to use disks previously attached to RocketRAID controller
on other controllers, please first delete any array information on the
disks. Otherwise your data may be lost when you want to put it back later.

Hey Paul,

I just bought this raid card and am trying to use 2x intel 520 240GB ssds via this card as a main boot drive. How do I go about doing this?? I have posted this question in the forum as well. And how do you boot to the raid management?? And BIOS version for the card you suggesting. I have installed the latest bios that was available in highpoint website!!

Thx
