ANNEX A 

Device programming FAQ

 

1. Problem with the console via COM-port. You can enter the BIOS Setup, but when DOS 
starts, it is no longer possible to get there using keyboard via terminal. What is the reason? 

 
The most likely reason for this problem is BIOS Setup. By default, the remote console integrated 
into the AMI BIOS is enabled only until the BIOS transfers control to the operating system. In order 
to enable the console I/O integrated into the AMI BIOS, you need to change the BIOS Setup 
settings - 

in the “Advanced -> Remote Access Configuration” section, and set the “Redirection after 

BIOS POST” parameter to “Always” (when the device is delivered, this parameter is set by default 
in “Boot Loader”). However, it should be noted that the console implemented in the AMI BIOS uses 
a system timer.

 

You can also use the FreeDOS tools (OS preinstalled by default), such as the 

MODE

 (change the parameters of I/O devices) and 

CTTY

 (change the standard I/O device) 

commands in the AUTOEXEC.BAT file: 

MODE COMm[:] [BAUD[HARD]=b] [PARITY=p] [DATA=d] [STOP=s] 

 

CTTY COMm 

 

COMm 

– COM- port used (COM1, COM2, COM3, COM4). By default, in the BIOS Setup settings 

for the COM1 (RS-232) port and for the COM2 (RS-232) port, the base addresses are 3F8h and 
2F8h, respectively. In order to use COM1 or COM2 (RS-232) for console I/O, the BAUD parameter 
must be set properly. 

BAUD 

– baud rate code: 96 – 9600 bit/s, 192 – 19200 bit/s. 

BAUDHARD 

– baud rate code: 96 – 9600 bit/s, 192 – 19200 bit/s, 384 – 38400 bit/s, 1152 – 115200 

bit/s.  

PARITY 

– parity (Even, Odd, Mark, Space, None). 

DATA 

– number of data bits (7, 8) 

STOP 

– number of stop bits (1, 2) 

Examples of recording in the AUTOEXEC.BAT file: 

MODE COM1 BAUDHARD=1152 PARITY=NONE DATA=8 STOP=1 

 

CTTY COM1 

 

MODE COM2 BAUD=96 PARITY=NONE DATA=8 STOP=1 

 

CTTY COM2

 

However, it is necessary to consider certain restrictions during the work with the console when the 
FreeDOS operating system is running (it is preinstalled on the integrated flash drive at the time of 
delivery), precisely: pressing such keys as “Backspace” and "←", "→" (while no such problems 
were found when working with MSDOS).
