ACARD AEC-6880M
Chapter 1 Introduction
1.1 Introduction
ACARD AEC-6880M is a high-performance Hardware RAID Ultra ATA-
133 adapter for PCI PowerMac. Its on-board Open Firmware supports
booting from IDE disks configured as RAID.
AEC-6880M supports all models of PowerMac which have a PCI slot,
including PowerMac G3, G4. For PowerMac older than G4, ACARD
AEC-6880M can boost the disk better. The performance can further be
improved by using a 7200rpm big capacity drive. Compared with the
original G4, the improvement can be as high as 300%. For PowerMac
G4, ACARD AEC-6880M allows Mac to add more IDE drives or to use
Hardware RAID by adjusting the easy RAID DIP Switch setting.
ACARD AEC-6880M adapter is the first Mac add-on card to support ANSI
X3T9.2 CAM ATA4/ATA5. The data transfer rate is up to 133 MB/sec per
channel, and meets the demand of multimedia, real time video.
ACARD AEC-6880M supports the true PnP function in Mac OS 8.5, OS
9.x and OS X. No software driver is needed for connecting an Ultra ATA
66/100/133 HDD. With the advanced function, the adapter is really user-
friendly. It coexists with the on-board IDE controller. The on-board BIOS
lets the system boot from ATA HDD.
