each of the System Setup categories in the Main menu
and the Boot Sequence submenu.

Time

resets the time on the computer's internal clock.
TIME
Time is kept in a 24-hour format (hours:minutes:
seconds). To change the time, use the plus and minus
keys. If you prefer, you can type numbers in each of the
appropriate fields.
NOTE: If your system is connected to a network, the
category may reflect the time maintained by the network
server, depending upon how the network is configured. In this
case, changing the category on your system has no effect.
TIME

Date

DATE
Your system automatically displays the day of the week
corresponding to the settings in the three fields that fol-
low (month, day-of-the-month, and year).
To change the date, use the plus and minus keys to increase
and decrease the numbers. If you prefer, you can type
numbers in the day-of-the-month fields.
NOTE: If your system is connected to a network, the
category may reflect the date maintained by the network
server, depending upon how the network is configured. In this
case, changing the category on your system has no

video BIOS code, but also allows it to be cached. Cach-
ing saves time for the microprocessor(s) by holding
available the most recently accessed data and instructions
in an intermediate storage area of static RAM (SRAM),
which is faster than system RAM. Shadowing and cach-
ing let the system manipulate video display data more
quickly and easily, improving video performance.
