If you choose the Custom option, you can change the individual time-out settings, such as the automatic turn-off time. The greater the idle time before turn off, the more battery power you will use. Using Disk Drives The small size and light weight of your OmniBook are made possible in part by advanced storage devices such as tiny plug-in cards and a miniaturized disk drive. The OmniBook floppy drive contains one slot (drive A). The OmniBook has one system drive for the hard disk (drive C), and two card slots (typically available as drives D and E).
Floppy drive (drive A) Lower card slot Upper card slot You can use the upper and lower card slots with plug-in PC cards much as you now use floppy disks. You can plug in a PC data-storage card and write data to it or read from it just as if it were a floppy disk. About the Internal Hard Disk Drive (Drive C) The hard disk (drive C) can be removed and replaced. For cautions and instructions on changing the hard drive, see "To replace the hard drive (drive C)" . About the Card Slot Drives • You can insert PC data-storage cards into the upper and lower card slots—they could be drives D and E, but not necessarily, since they can be automatically reassigned.
Such cards function as disks (and are often called “disks,” rather than “cards”). These disks provide a convenient way to store backup data and exchange data with other computers, or simply to expand your data-storage capacity. (See “To insert a PC card“ .) • If you insert a double-height (type III) card into the lower slot (suppose it’s drive E), the drive for the upper slot (suppose it’s D) exists but isn’t 20
