I got an assembly H50, I can boot up with the V4.3.3. CD and managed to
install the OS. After installed completed, I happily see the logon screen.
However, I cannot login at all, it keep showing the login prompt. I did not
set any password, or I have no chance to put at all. Any idea? Thanks.

If you're talking about a serial console, AIX uses strict RS-232
discipline, so cheap pseudo-crossover cables won't work.

You'll need a real crossover cable (deals with tx/rx,cts/rts,dtr/dsr and
friends).

Hi, Jose,

I think you might be right.
I can use the serial port RS232 with hyper-terminal to do the installation,
and it completed successfully. It then re-boot and give me the login screen,
however, I just cannot login.
After I change the VGA monitor, keyboard, and mouse, it run smoothly. :-)
but I still don't understand why?

Rgds,

When installing AIX using a serial console the device driver for the
serial port is not full function.

After the installation "getty" runs on the serial port. This device
driver is full function and requires all of the RS232 control signals.
i.e. DCD, DTR, DSR.

Ummm - when you mention "VGA(graphics adapter)/keyboard/mouse": in a
nutshell, I BELIEVE the graphics adapter is (always) considered the
primary console (lft0) - regardles of where you put the "tty".

Recommended "fix" - shutdown your system, remove the graphics adapter
and the keyboard/mouse from the connectors, attach the tty to S1 (make
sure it's configured correctly), power up the system and answer the
question that will appear on the tty somewhere between the BIST, POST
(IIRC).

Hope that helps somewhat...

PMS
p.s. If your system is up, and before you do the above - if that's your
choice <G> - log in (however you can) and take a look (smit console) to
see what the system thinks is the console - my bet..."lft0"...Paul
