aixlover,

An x4150 is an x86 based system, so it most likely comes with a video card. Most install scripts set the system to boot to its video console, in which case there is no output on the serial console. If you don't have a monitor handy, you can tell if the system is using its video output by looking at /boot/grub/menu.lst If you see something like this :

Code:

title Solaris 10 5/08 s10x_u5wos_10 X86
kernel /platform/i86pc/multiboot
module /platform/i86pc/boot_archive

Your system is using the video display. In order to fix this, you need to modify your grub configuration.

The menu.lst file is fairly easy to understand, but in order to boot with a serial console, you should add a section to the top of the various boot options like this :

Code:

title Solaris 10 5/08 s10x_u5wos_10 X86 - Serial Port (ttya)
kernel /platform/i86pc/multiboot -B console=ttya
module /platform/i86pc/boot_archive

Note the -B console=ttya. This webpage has more information - Modifying Boot Behavior on x86 Based Systems - System Administration Guide: Basic Administration

I forgot to mention that after making this change, you will need to reboot.

cvc(7D) 							      Devices								   cvc(7D)

NAME

       cvc - virtual console driver

DESCRIPTION

       The  cvc  virtual  console  driver  is a STREAMS-based pseudo driver that supports the network console. The cvc driver interfaces with con-
       sole(7D).

       Logically, the  cvc driver sits below the  console driver. It redirects console output to the cvcredir(7D) driver if a network console con-
       nection is active. If a network console connection is not active, it redirects console output to an internal hardware interface.

       The cvc driver receives console input from  cvcredir and internal hardware and passes it to the process associated with /dev/console.

NOTES

       The   cvc facility supersedes the SunOS wscons(7D) facility, which should  not be used in conjunction with  cvc. The  wscons driver is use-
       ful for systems with directly attached consoles (frame buffers and keyboards), but is not useful with platforms using cvc,  which  have	no
       local keyboard or frame buffer.
