V. DESKTOP MANAGEMENT Desktop Management Interface (DMI) Introducing the ASUS DMI Configuration Utility This motherboard supports DMI within the BIOS level and provides a DMI Con- figuration Utility to maintain the Management Information Format Database (MIFD). DMI is able to auto-detect and record information pertinent to a computer’s system such as the CPU type, CPU speed, and internal/external frequencies, and memory size.
V. DESKTOP MANAGEMENT Using the ASUS DMI Configuration Utility Edit DMI (or delete) Use the ←→ (left-right) cursors to move the top menu items and the ↑↓ (up-down) cursor to move between the left hand menu items. The bottom of the screen will show the available keys for each screen.

SCO UNIX floppy disk. Windows 95 support is also available using the device drivers included within the Windows software. The ASUS PCI-SC200 and ASUS PCI-SC860 are Plug and Play adapters that are auto detected by BIOS and current operating systems that support Plug and Play features.
VI. ASUS PCI SCSI Cards Setting Up the ASUS PCI-SC200 & PCI-SC860 There are two jumper settings you may need to make on the ASUS PCI-SC200 to set it up. One setting assigns the PCI INT interrupt, the other sets the card’s termination.
Not Terminated Terminator Setting (Terminated / Not Terminated) Decide whether or not you need to terminate the ASUS PCI-SC200 based on its position in the SCSI chain. Only the devices at each end of the chain need to be terminated. If you have only internal or only external devices connected to the ASUS PCI-SC200, then you must terminate the ASUS PCI-SC200.
SCSI identification number that is not in use by any other SCSI device. There are eight possible ID numbers, 0 through 7. The ASUS PCI-SC200 and ASUS PCI-SC860 cards have fixed SCSI IDs of 7. The SCSI ID serves two purposes: •...
