Introduction
This technical manual applies for the mainboard D1085. This system board is available in different
configuration levels. Depending on the hardware configuration of your device, it may be that you
cannot find several options in your version of the system board, even though they are described.
Further information e. g. the complete Technical Manual for the D1085 and the Reference Manual
for the BIOS Setup are provided on the "Drivers & Utility" CD. For detailed information please
look at chapter 3.

2 Mechanics
!Computer mainboards and components contain very delicate IC chips. To protect
them against damage caused from electric static, you have to follow some
precautions:
• Unplug your computer when you work inside.
• Hold components by the edge, don’t touch their leads.
• Use a grounded wrist strap.
Place the mainboard and the components on a grounded antistatic pad whenever
you work outside the computer.
Once you have installed the system board, you should remove the battery
protection (i.e. the thin plastic plate between battery and contact spring).

Recovering System BIOS - switch 2
Switch 2 enables recovery of the old system BIOS after an attempt to update has failed. To restore
the old system BIOS you need a Flash BIOS Diskette (call customer service).
on The System BIOS executes from floppy drive A: and restores the System BIOS on
the system board.
off The System BIOS is started from the system board (default setting).
Write protection for floppy disks - switch 3
Switch 3 is used to define whether floppy disks can be written or deleted in the floppy disk drive. To
write and delete floppy disks, the write -protection in BIOS setup must be disabled (in menu Security,
the field Diskette Write must be set to Enabled).
on The floppy disk drive is write-protected.
off Read, write and delete floppy disks is possible (default setting).
