This computer has an automatic input voltage sensing power

supply (between 

 for USA and Canadian use, and 

 for

use in other countries). There is no manual switch

When connecting the mouse and keyboard, be careful to

plug them into the 

 ports. Although they are

physically identical, they are not interchangeable, and

damage may occur to the ports or the 

 board.

When installing a floppy disk drive as drive B, remember to

set the drive select jumper to the second position and attach

the pass-through connector on the floppy drive controller

cable to the drive, not to the end connector.
If the drive does not function normally, make sure that the

drive type has been correctly selected in Setup. Also check

that any necessary drivers have been installed correctly.
If you have installed two floppy disk drives, remember that

the computer will boot 

 drive B when a disk is inserted

do not exceed the maximum capacity (in MB) of your drive.

 there is no match for your drive, enter the 

parameters using the User 

 option.

the installation at high speed. If this does not work properly,

try switching to low speed for the installation If you are still

copy-protection method, try loading it at high speed. If this

does not work, enable Auto Speed in Setup on the Reference
