I want to convert mt server to headless
I have a Centos 5 installation that I did with a PCIe video card. Now that the install in complete, I'd like to convert the system to headless. I have modified the menu.lst file so that the serial port is the console and I've made sure that a getty is running on the serail port after boot.
However, if I remove the video card, the system never boots. Of course, I cannot tell what it is doing but it never gets to the point where grub outputs on the console.
The only hint I have is that if I put the original video card back in, it works fine. If I put another, different video card in, it won't boot. This second card has a different video chipset so that may be an issue.
Does anyone have any idea what the proper procedure is for beheading a linux system?
