Epson ActionNote - Manual (Page 40)

If you install an operating system, it writes to the boot sector as
you install it. In this case, you probably do not want the virus
warning feature enabled. Therefore, your system initially has
the virus warning feature disabled. This way you won’t need to
respond to the virus warning prompts if you install an
operating system. Once you have installed it, you can enable
this option to take advantage of the virus warning feature.
Setting the Default Speed
Your computer’s processor can operate at two speeds: High
(33 MHz) or Low (8 MHz). The processor is factory set to High
speed, where it can access memory faster. If you want the
computer to always start at Low speed, change this option to
Low.
Use High speed for everything you do unless you have an
application program that requires a slower speed. Some
applications, like word processing programs, don’t need the
performance of a high CPU speed. (Check your application
software manual for guidelines.) You may also want to set this
option to Low to conserve battery power.
