Bitsyload erases a section of flash memory on the Bitsy (iPAQ
3650 or 3830) and copies new information into it, using the format
required by the Compaq boot loader. The required first argument
is the destination, either k for /dev/flash/kernel or r for /dev/flash/ramdisk.
The optional second argument
is the name of the file to load. The default kernel file is /sys/src/9/bitsy/9bitsy
and the default ramdisk file is /sys/src/9/bitsy/ramdisk. |
Light sets the intensity of the display backlight. The values
for intensity are:
Pencal calibrates the display with the touch screen on a Bitsy. It loops prompting the user with crosses whose center that the user must touch with the stylus. After a consistent set of touches, it writes the calibration both to the kernel and to standard out. It is normally called by the bitsy's /bin/cpurc.
Params copies the contents of the file /dev/tmpparams, into the flash partition, /dev/flash/params, or if the –f flag it set copies in the opposite direction.
Keyboard creates a virtual on–screen keyboard and, unless the –n option is specified, a scribble area. A user inputs characters by tapping the keys or by drawing characters in the scribble area (see scribble(2)). It is usually run as the keyboard command for rio(1) using rio's –k option.
Prompter is a small editor used to configure parameters when a
Bitsy boots. It displays the file and starts up a keyboard and
scribble pad for input. Clicking with the stylus in the text selects
where input characters will go. Pressing Button 5 (top left side
of the Bitsy) or typing the Esc key on the keyboard causes
prompter to write back the updated file and exit; Del causes prompter
to exit without writing the file. The –n flag suppresses the scribble
Prompter, params, and calibrate are used in only one place, the
