BASEBOARD DESIGN EXCEPTIONS

BASEBOARD DIMENSIONS

The Advanced/ZP is 3.0" shorter than the Baby-AT standard. The shorter board length may require some chassis to be modified to add additional mounting holes.

MOUNTING HOLE PLACEMENT

The mounting holes located in the bottom left and right corners of Figure 1 are pseudo Baby-AT standard and are available in many, but not all, Baby-AT compatible chassis.

FRONT PANEL CONNECTORS

There is no front panel connector on the baseboard for a Turbo/Deturbo switch. The processor speed can be set either through a parameter in the CMOS Setup Utility, or from the keyboard (<CTL><ALT><+> = Turbo, <CLT><ALT><-> = Deturbo). Changing processor speed from the keyboard may be prohibited by the operating system, or when the processor is in protected mode.

Setting the processor to deturbo (or slow) only slows the processor to the approximate equivalent of a 25 MHz clock rate, not the standard 8 MHz clock rate.

JUMPERS/SWITCHES

There is no Color/Mono jumper/switch on the baseboard to specify Monochrome or Color video mode at boot, the BIOS will automatically detect the type of video card installed.

Also, there is no Flash write protect jumper/switch, the BIOS needs to be able to write to FLASH to support the Plug and Play features.
