Chapter 3: The Software
The Filesystem
• If the minimum power consumption limit is set higher than the maximum,
the power of the device will remain elevated for as long as the application
requires the device.
• If the OS transitions to a suspended power state, application-imposed
minimum power limits will be set aside while the OS is suspended.
3.5 The Filesystem
The filesystem of the 7535 appears as one unified space. However it is composed of
several different types of memory: internal RAM, internal flash, and installed
memory cards.
When the 7535 cold-boots, the bootloader installs the operating system into RAM.
The resulting filesystem—the
\Windows, \Program Files, \My Documents direc-
tories and so on—resides in RAM, and is cleared during a cold boot.
Note: In normal usage, the 7535 is not cold-booted. Unlike many computers, the
unit is merely suspended when it is not in use, and the RAM retains its
contents.
The 7535’s internal nonvolatile flash memory and any available memory cards are
made available to this filesystem. That part of the 7535’s internal flash memory
available to the user appears as the
\Flash Disk folder. Each partition on a
memory card appears as a separate folder under the root folder. (Most memory cards
have one partition by default; this can be changed through the Storage Manager.)
Memory-card folders are named as follows:.
