7. BIOS

7.1BIOS Settings

Prometheus uses a BIOS from Phoenix Technologies modified to support the custom features of the ZF Micro ZFx86 chip and the Prometheus board. Some of these features are described here.

To enter the BIOS during system startup (POST – power on self-test), press F2.

Serial Ports

-The address and interrupt settings for serial ports COM1 – COM4 may be modified. COM1 and COM2 address and interrupt settings are done in the BIOS, Advanced menu, I/O Device Configuration. See page 27 for details.

-The addresses of COM3 and COM4 are configurable in the BIOS. Select Advanced menu, Advanced Chipset Control, ISA I/O Chip Select Setup. See page 27 for details.

Parallel Port

-The parallel port settings may be modified on the same screen as serial ports COM1 and COM2 (I/O Device Configuration).

Data Acquisition

-The on-board data acquisition circuit is modified on the same screen as serial ports COM3 and COM4 (ISA I/O Chip Select Setup).
