HDD Block mode
HDD Block Mode accelerates disk transfers. A performance improvement is especially
noticeable with applications that utilize the multiple sector transfers for reading and writing large
files. Some older applications may not tolerate this acceleration technique, so the default setting
is "Disabled" for compatibility purposes. If you are using Windows applications, you can enable
this to accelerate disk transfers.
Thermal Monitor
The default setting is "Disabled." If you use your computer in a very warm environment and it
has either a high-speed Pentium installed or power management disabled, enable this feature to
prevent the Pentium processor from overheating. In a normal environment with power
management enabled, use the default to maximize system performance.

Video Display Drivers
This section explains the function and use of the WinBookXP5 video display software options
and controls.
Display resolution and the number of colors displayed is governed by software video display
drivers that work with the display controller circuitry in the computer. Your WinBookXP5 uses a
display controller and drivers from Chips and Tecnologies Inc. Drivers for both Windows and
selected DOS applications come with the computer. The LCD screen on your computer can
display a maximum resolution of 640 pixels horizontally by 480 pixels vertically with a
maximum of 4096 colors (12-bit color). In practice this means that the display drivers will fully
display 16 colors	 (4-bit color) or 256 colors (8-bit color) on the LCD screen, but will only
display 4096 colors out of the Hi Color (65,000 color) or True Color (16 million color) color
palettes. The Windows display driver will display all the Run... command in the supported
resolutions and colors on any suitable external monitor connected to the monitor port at the rear
of the computer.
The Windows Driver
The C&T Windows display driver supports four screen resolutions and five color depths as well
as enhancements for both the LCD and external CRT (monitor) displays. This results in a
number of possible resolution/color depth/ feature combinations. To simplify selecting the
combination you want to use, you can change the display settings from the 'Settings' portion of
the 'Display Properties' section of the Windows Control Panel.
