Chapter 1 Introduction
1.1 Overview
ACARD AEC-6885MS, AEC-6885M and AEC-6885MLP are 4-channel PCI-to-IDE
ATA-133 RAID adapters for Macintosh workstations and servers. AEC-6885MS is a
64-bit, 33MHz controller with transfer rate of 266MB/s while AEC-6885M a 64-bit,
66MHz one with transfer rate of 533MB/s. As for AEC-6885MLP, it is the same as
AEC-6885M except that it’s low profile. They all support RAID 0, 1, 0+1 and normal
modes. The 48-bit LBA (Logical Block Addressing) technology makes them good
for “Big Drives” technology over 137GB. The enclosed RAID utility lets you manage
RAID subsystem smoothly via a GUI.

Chapter 2 Hardware Installation
From this chapter on we take AEC-6885M as an example. Before installing an IDE
hard drive to the adapter, the IDE hard drive must be adjusted as Cable select or
Master mode through jumper setting. Perhaps the hard drive contains some data,
that will cause Mac OS installation difficult in striping mode, so adjust AEC-6885M
DIP switch to normal mode at first.
If an IDE hard drive has contained data or any version of Mac OS, it is strongly
recommended to back up the old data before installing the hard drive to the adapter.
In the normal mode of AEC-6885M, you have to initialize or erase (in OS X) the hard
drive first. Besides, you need to inspect if every hard drive is all right, too. Then,
shut down your computer to adjust the DIP switch to a RAID mode you want. Cer-
tainly you have to enter Disk Utility to erase or partition those new RAID volumes.
2.1 Quick Installation
1. Open the Mac computer’s or workstation’s case (refer to Mac manual).
2. Choose an empty PCI slot to insert AEC-6885M.
3. Install hard drives into the Mac computer or workstation.
4. Connect AEC-6885M and the hard drives with ATA-133 cables.
5. Close the Mac computer’s or workstation’s case.
For the installation of hard drives with AEC-6885M on Power Mac G4 Mirror Door
computer, please refer to Appendix.
The pictures of AEC-6885M and ATA-133 cable are shown on the next page.

2.2 HDD Compatibility
AEC-6885M is specially designed for DMA hard drives. It supports most ATA 66/
100/133 hard drives of the following brands.
nIBM
nMAXTOR
nSEAGATE
nWESTERN DIGITAL
2.3 Before Installation
Before the installation of AEC-6885M, you need to know the following four modes in
order to make the best use of the adapter. However, it is strongly recommended to
use hard drives of the same model and capacity.
Normal Mode (NONRAID)
1. If you set the DIP switch as normal mode, you will use AEC-6885M as an ordi-
nary IDE adapter.
2. AEC-6885M doesn’t support ATAPI devices such as CD/DVD-ROM.
Striping Mode (RAID 0)
1. Striping means to divide a piece of data into several small pieces of data with the
same size. The data is accessible from several hard drives at the same time.
This mode can greatly enhance the overall efficiency, but it doesn’t provide any
fault tolerance.
2. If hard drives are different in capacity, AEC-6885M will take the hard drive of the
smallest capacity as the standard, and multiply with the total number of hard
drives. The value will be the total capacity of striping array.
3. RAID 0 requires at least two hard drives.
4. If you need two sets of RAID 0 in AEC-6885M, you have to install two hard drives
to form the first set. Then shut down the computer, and install another two hard
drives to form the second set. If you install four hard drives at the same time,
AEC-6885M still forms them as one set.

5. If you want to give up two arrays (each array has 2 HDDs) and create a new
striping array (4 HDDs), please delete the two arrays in 6885M RAID Utiltiy and
reboot.
6. The DIP switch on AEC-6885M is used to set RAID mode. It doesn’t allow two
modes at the same time. For example, you have connected two hard drives to
form RAID 0, but if you add one more hard drive to AEC-6885M, you won’t be
able to use the independent one.
Mirroring Mode (RAID 1)
1. Mirroring means to save every piece of data into two hard drives at the same
time. The two hard drives contain the same data, therefore the efficiency of this
mode is not higher than that of a general hard drive. The main function is that
when one of the hard drives fails, another will keep working, and thus data won’t
be lost.
2. If the capacity of hard drives is different, AEC-6885M will take the hard drive of
the smallest capacity as the standard. And the whole capacity you can use is that
samllest hard drive.
3. RAID 1 requires two hard drives.
4. The DIP switch on AEC-6885M is used to set RAID mode. It doesn’t allow two
modes at the same time. For example, you have connected two hard drives to
form RAID 1, but if you add one more hard drive to AEC-6885M, you won’t be
able to use the independent one.
Striping + Mirroring Mode (RAID 0+1)
1. RAID 0+1 has the advantages of RAID 0 and RAID 1. It owns the high efficiency
of RAID 0 and the data security of RAID 1.
2. RAID 0+1 requires 4 hard drives.
3. If the capacity of hard drives is different, AEC-6885M will take the hard drive of
the smallest capacity as the standard, and muptiply with two. The value will be
the total capacity of RAID 0+1.

2.4 Installation
The complete installation is described as follows.
Step 1. Find out color pin 1 on the ATA-133 cable’s connector at one end.
Step 2. Connect it to IDE port 1 on AEC-6885M.
Step 3. Find out color pin 1 on the ATA-133 cable’s connector at another end.
Step 4. Find out pin 1 on the IDE hard drive’s connector.
Step 5. Connect the cable to the hard drive by aligning pin 1 to pin 1.
Step 6. Connect the 4-pin power cord to the IDE hard drive.
2.5 DIP Switch Setting
RAID configurations must be set on AEC-6885M’s DIP switch. However, after in-
stalling hard drives to the IDE ports, do not arbitrarily change the positions other-
wise the adapter may misunderstand and the data may be lost.
