Drive controllers and connectors

The system board supports several controllers for drives and other 
peripherals. Connectors to link these controllers to the appropriate devices 
are also provided.

Secondary and primary hard drive connectors (G, H)

This is an integrated dual-channel Ultra-DMA PCI/IDE interface with two 
IDE connectors capable of controlling up to four IDE devices and 
supporting PIO Modes 0-4. Ultra-DMA provides faster access to IDE 
devices that are Ultra-DMA compliant while maintaining support for IDE 
devices that do not support the Ultra-DMA specification.

Diskette drive connector (I)

The diskette drive controller and connector on the system board support up 
to two diskette drives of 360 KB, 720 KB, 1.2 MB, 1.44 MB, and 2.88 MB 
formats.

SCSI connectors (X, Y)

This integrated Adaptec

®

 AIC

™

-7890 SCSI controller is a 

high-performance, PnP compliant, single-chip PCI local bus-to-Ultra2 
SCSI master host adapter. Its advanced SCSI I/O cell technology ensures 
data integrity for higher I/O bandwidth requirements with data rates of 
40-MB/sec in Ultra mode and 80-MB/sec in Ultra2 mode.

Additional features:

•

Dual LVD 16-bit (68-pin) PCI-to-Wide Ultra2 SCSI connectors

•

Full 32-bit PCI bus master implementation maximizing data 
transfer on PCI local bus at 133 MB/sec data bursts

•

SCAM (SCSI Configured Automatically) Level 1 for 

Windows 95

®

, enabling automatic configuration of new devices 

without having to reboot the system.
