AHARD RAID 66

Chapter 1 Introduction

1.1 Overview

The ACARD AEC-6860M, AHARD RAID 66 is the first high performance

Hardware RAID 0 PCI bus master Ultra-ATA 66 adapter for PowerMac.

With on board Open Firmware that supports booting from IDE disks

configured as RAID.

The AHARD RAID 66 supports all models of PowerMac which have a PCI

slot, include PowerMac 7200, G3, G4. For PowerMac older than G4,

AHARD RAID 66 can really boost the disk performance better. The

performance can further be improved by using 7200rpm big capacity

drive. As compared with the original G4, the improvement can be as high

as 300%. For PowerMac G4, AHARD RAID 66 will allow Mac to add

more IDE drives or to use hardware RAID by adjust the easy RAID DIP

Switch setting.

The AHARD RAID 66 adapter is the first Mac add-on card to support

ANSI X3T9.2 CAM ATA4/ATA5, data transfer rate up to 66 MB/sec and

meets the demand of multimedia, real time video. It is also backward

compatible with traditional ATA modes.

It supports the true PnP function, in Mac 8.5 and later version, there are

no software driver needed for connecting an Ultra ATA 66/100 HD.

With the advanced function, the adapter is real user friendly. It coexist

with the on board IDE controller. On board BIOS supports system to

boot from ATA HDD. AHARD RAID 66 also supports multitasking to

improve the CPU performance.

AHARD RAID 66

Chapter 2 Hardware Installation

The hardware installation is a simple Hardware RAID host adapter installa-

tion. Please follow the following instruction.

Before you install an IDE device into the AHARD RAID 66, you may set

the IDE device as “Master or Slave” mode by adjusting the DIP switch

setting. As hard disks may contain some unclean data which might cause

the Mac OS installation problems under a striping mode processing.

Please adjusting AHARD RAID 66 DIP switch for a normal mode first.

You are about to connect an IDE hard drive on AHARD RAID 66, please

note that if you have an old disk which already have the data or a version of

Mac OS installed, we recommend that you have to backup your data

before any installation and re-install the Mac OS after the hardware instal-

lation. It will not work without re-install the Mac OS even the old disk have

a version of Mac OS from the beginning. Due to the way RAID card

commands are different than the ON-Board IDE controller, it will create

reading/writing error, so we strongly recommend that after hardware

installation just treat the IDE hard disk as a new disk. If you want AHARD

RAID 66 to do striping, after processing “initialize” under normal mode,

then adjusting AHARD RAID 66 DIP switch for a striping mode to

process disk “initialize” again.

2.1 Quick start hardware installation:

1. Open your Mac’s case (Please reference your Mac’s manual)

2. Choose an empty PCI slot and plug in your AHARD RAID 66 adapter

3. Fix your hard drive in your Mac

4. Connect your ATA-66 cable from adapter to hard drive

5. Close your Mac case

! If you want to connect 2 hard drivers in the same channel,

please check the Master / Slave jumper.

! AHARD RAID 66 adapter DIP switch set on normal mode as a

IDE port extension.

! As hard disks may contain some unclean data which might

cause the Mac OS installation problems. If you want to do RAID

0 function, the “initialize” must be processed first under normal

mode then turn off your computer to set the DIP switches for

striping mode and re-do the “initialize” again.

2.2 AHARD RAID 66 adapter compatibility list

AHARD RAID 66 is designed specifically for DMA Harddisk, we have fully

tested many kind of Harddisk available in our lab, and the compatibility

with different controller cards even in Mac is very high. The AHARD RAID

66 support many DMA 66/100 hard drives from the following vendors:

!IBM

!MAXTOR

!QUANTUM

!SEAGATE

!WESTERN DIGITAL

2.3 What you should know before the installation

Before you install the AHARD RAID 66, the following tips may help you to

get the best performance of your system:

Striping Mode

!If two hard disks are in different storage capacity, AHARD RAID 66 will

treat smaller one as a standard capacity, and double the standard

capacity as a total available disk capacity.

!For one pair connection, jumper setting on each hard disk must set

at the same position either both “Master” or both “Slave”. Two hard

disks can not connect in the same connector cable (same IDE port)

on AHARD RAID 66 card.

!When using two pairs hard disk on AHARD RAID 66 please identify

each hard disk jumper have been set at “Master” and “Slave” position

on each IDE port cable connector with hard disk (please refer to

Figure 1).

AHARD RAID 66

!For each connector port on AHARD RAID 66 to connect with hard

disk, either same connector cable can not be set as both “Master” or

both “Slave”.

!In order to get a better performance, please use same model or brand

hard disk and Ultra DMA 66 or 100 hard disk.

Normal Mode

!Two AHARD RAID 66 card IDE connector port as normal IDE port

extension.

!When using two hard disks connected with AHARD RAID 66 at the

same IDE port (on same cable) by one connector cable please

identify that the hard disk jumper must be set as one “Master” and

one “Slave” position on each hard disk. The two hard drive can not be

set as both “Master” or both “Slave”.

!If using two IDE connector port on AHARD RAID 66 to connect with 4

hard disks, jumpers setting and hard disks boot sequence will follow

the jumpers setting from IDE 1 Master, Slave and then IDE 2 Master,

Slave.

!In order to get a better performance, please use Ultra DMA 66 or 100

hard disk.

AHARD RAID 66

The cabinet connection methods:

Step 1. Find out pin 1 of 40-pin IDE connector on IDE hard disk.

Step 2. Find out a color line of the internal IDE ribbon cable indicating pin

1 of connector.

Step 3. Connect the internal IDE cable to IDE hard disk aligning with pin-

1 to pin-1.

Step 4. Connect 4-pin power cable to IDE harddisk.

2.4 AHARD RAID 66 cable & power installation

Before you connect AHARD RAID board to your device, recognize the

different interface connectors of SCSI and IDE on the board. The longer

connector on external circuit board, which has 68 pins, is the SCSI

connector. Inside the cabinet, there is IDE ribbon cable connection.

Please note this connector will be connected to IDE harddisk.

For the Hard Disk’s jumper setting (Master / Slave), please refer to
