For performance issues, we strongly suggest you don’t install a CD-ROM drive on the
same IDE channel as a hard disk. Otherwise, the system performance on this channel may
drop. (how much depends on your CD-ROM drive performance)
Note
!
The Master or Slave status of the hard disk drive is set on the hard disk itself. Please
refer to the hard disk drive user’s manual.

Attach a PS/2 keyboard connector to this 6-

keyboard for best compatibility.
