The DiskOnChip may also contain the operating system thereby permitting systems to boot without a hard disk The DiskOnChip may also be configured as the boot device in systems with a hard disk see the section Configuring the DiskOnChip as the First Drive The DiskOnChip is a self contained device the installation of which does not necessarily require any software installation The basic design of the DiskOnChip allows for full upward and downward compatibility by supporting an unlimited capacity Future DiskOnChip devices with higher densities will be fully compatible with today s capacities of 2 to 288 MBytes and the standard DiskOnChip socket Blue Chip Technology Limited 0127 1029 Page 13 ATOM USER MANUAL HARDWARE DESCRIPTION INSTALLING THE DISKONCHIP Before installing or removing the DiskOnChip please read the section on Electro Static Discharges at the beginning of this manual It is essential that you discharge any static electricity from your body before touching the board or DiskOnChip module Use the following procedure to install the DiskOnChip e Align pin 1 on the DiskOnChip with pin 1 of the socket adjacent to the battery e Push the DiskOnChip into the socket carefully until it is fully seated e Check that the DiskOnChip is installed securely and that there are no bent pins Caution The DiskOnChip may be permanently damaged if installed incorrectly To install the DiskOnChip as drive C on a system without a hard d
3. CPU The ATOM single board PC is designed to operate with Pentium class Processors running at 2 2 2 8 2 9 or 3 3 Volts An on board voltage regulator circuit provides the required voltage for the processor from the incoming 5 volt power supply The Pentium processor maintains full backward compatibility with the 8086 80286 1386 and Intel486 processors It supports both read and write burst mode bus cycles and includes separate on chip code and data caches which employ a write back policy Also integrated into the Pentium processor is an advanced numeric co processor which significantly increases the speed of floating point operations whilst maintaining backward compatibility with Intel486 math co processor and complying to ANSI IEEE standard 754 1985 PROCESSOR SOCKET SZIF Processor replacement requires the careful use of a flat blade screwdriver A heatsink and fan will be required for many of the processors These will make CPU fitting difficult because of their placement especially if they reduce the mechanical advantage of the screwdriver The screwdriver can be cranked to overcome this by putting a bend in it at the point it contacts the edge of the CPU 3 5mm screwdrivers have been found to be ideal Insert the CPU carefully observing the missing pin of the polarisation corner inspect the pins for alignment first Place the screwdriver all the way into the special aperture in the socket between CPU and large capacitors Usi
