What is the Purpose of the Setup Page?
You can enter the diskette (floppy disk) drive in your mass storage module and the
memory card drive in your CPU on this page.
Drive A
At the first power up or after the INS key has been pressed during booting, the
BIOS setup detects whether the CPU has been expanded by a mass storage
module and whether it therefore has a floppy disk drive available or not.
• If a floppy disk drive is available, the BIOS assigns drive A to it by activating the
option button “1.44 Mb”.
• If a floppy disk drive is not available, the BIOS assigns drive A to the memory
card drive by activating the option button “MemCard”.
If you do not want either of the two drives entered, activate the option button
“NONE”.
The other Drive A settings are not significant at the present time.
Drive B
Drive B stands only for the memory card drive within the CPU if a floppy disk drive
is entered in Drive A.
• Activate the option button “MemCard” if you want to work with a memory card.
• Otherwise, activate the option button “NONE”.
The other Drive B settings are not significant at the present time.
