Eagle 450 Initialization Routine
Before relying on the CMOS parameters, the AM-138 boot code checks the validity of the CMOS
contents by verifying the parameter checksum. If the checksum verifies, the system front panel displays
"C5" while it verifies CMOS, and boots using the current CMOS parameters. If you want to change the
CMOS parameters, press
ESC
when the "C5" displays (you have approximately three seconds). This
displays the CMOS configuration menu, as described below.
If the CMOS checksum test fails, the front panel will blink "CE" for several seconds, then switch to
"CC" while the boot code tests CMOS RAM to ensure that it is working. If the RAM test fails, the boot
code displays "CF" on the front panel and the system tries to boot using the default settings shown
below. If this is the case, contact Alpha Micro's Technical Assistance Center.
CMOS Menu Options
To enter CMOS Setup, first make sure no one else is using the computer. Then, press the Reset button.
When "C5" appears on the front display panel, press
ESC
on the boot terminal to interrupt the boot
process and access the CMOS Configuration menu. You have about three seconds to press
ESC
.
The port 0 terminal’s baud rate
must
match the current CMOS setting (default is 19.2K), or CMOS
will not recognize the
ESC
character.
The CMOS menu looks like this:
