You can easily customize the cpuModule by stacking PC/104 modules such as video controllers,
modems, LAN controllers, or analog and digital data acquisition modules. Stacking PC/104 modules
on the cpuModule avoids expensive installations of backplanes and card cages and preserves the
module's compactness.
RTD Enhanced Award BIOS is also implemented in the cpuModule. This BIOS supports ROM-
DOS™, MS-DOS, Linux, and Windows operating systems. Drivers in the BIOS allow booting from
floppy disk, hard disk, Solid State Disk, boot block flash, or DiskOnChip®, thus enabling the system
to be used with traditional disk drives or non-mechanical drives.
The cpuModule and BIOS are also compatible with most real-time operating systems for PC com-
patible computers, although these may require creation of custom drivers to use the SSD and watch-
dog timer.
