Page 3: General Description
PCI SCSI Device Management System (SDMS™) software operates the chipset, but the design of the chipset does not prevent other software to be used with it. BIOS support for this chipset is incorporated in the ASUS moth- erboard BIOS. -

SCSI bus when setting up your system. The cable provided is matched for a Fast/Ultra/Ultra2 SE or LVD operation. This cable also has built-in LVD termination since most Ultra2 hard disk drives are not made with onboard LVD termination. ASUS LSI SCSI User’s Manual... -
Page 5: Connecting Your Scsi Peripherals
If only internal SCSI device connections on your integrated SCSI have been made, then terminate the last internal device on the SCSI bus. You must disable the termination on all other devices. Termination on the LSI integrated SCSI integrated SCSI is automatically enabled in this case. ASUS LSI SCSI User’s Manual... -

If the utility is available, the following message also appears on your monitor: Press Ctrl-C to start ASUS Configuration Utility... This message remains on your screen for about five seconds, giving you time to start the utility. If you decide to press “Ctrl-C,” the message changes to: Please wait, invoking ASUS Configuration Utility... - Page 9 Adapter Boot Order The adapter boot order allows you to set the order in which host adapters will boot when you have more than one ASUS integrated SCSI in your system. When this option is selected, the Boot Order menu appears: To change an adapter’s boot order, select it and press Enter.
- Page 10 Go into the Configuration Utility to change settings. Parity – The PCI to SCSI host adapters always generate parity, but some older SCSI devices do not. Therefore, you are offered the option of disabling parity checking. ASUS LSI SCSI User’s Manual...
