The 6181 Computer BIOS is a Phoenix OEM BIOS. It is contained in a
flash EPROM, and can be upgraded in the field using a factory-provided
DOS utility. The 6181 BIOS varies with the 6181 display option. The
CPU card ships with the proper BIOS for the selected display. Note that
exchanging CPU cards between units may cause BIOS incompatibilities.
Accessing the BIOS Setup Screen
The BIOS Setup screen can be entered during power-up by pressing the
F2 key immediately following the RAM test. Because the keyboard is
not buffered during this stage of power-up, the F2 key may need to be
repeatedly depressed to enter the BIOS Setup screen.
Note:
You may need to determine the installed version of the
BIOS before contacting technical support. The BIOS Setup
screen displays the installed version of the BIOS.
