Follow-up Comment #2, bug #14893 (project grub): Hi Everyone, I believe I have found the problem. Well, I was able to get mine working anyway. Here are the changes I needed to make.
#boot=/dev/sda default=0 timeout=10 serial --unit=0 --speed=9600 --word=8 --parity=no --stop=1 terminal --timeout=10 console serial #splashimage=(hd0,0)/grub/splash.xpm.gz title CentOS (2.4.21-37.ELsmp) (console port output) root (hd0,0) kernel /vmlinuz-2.4.21-37.ELsmp ro root=/dev/md0 console=ttyS0,9600 console=tty0 initrd /initrd-2.4.21-37.ELsmp.img title CentOS (2.4.21-37.ELsmp) (serial port output) root (hd0,0) kernel /vmlinuz-2.4.21-37.ELsmp ro root=/dev/md0 console=tty0 console=ttyS0,9600 initrd /initrd-2.4.21-37.ELsmp.img There are only 2 things that really changed in the grub.conf file and 1 change in the BIOS settings. 1) I changed the order of the terminal line. I mis-understood the documentation and thought that the terminal would default to serial if it was first in the list. That apparently is incorrect. It will take the last in the list. This meant that the terminal line and kernal line were at odds with each other for an unattended boot. I also broke the different boot methods out into their own entries, thus simplifing matters. Most of this is all cosmetic or done for simplicity. What apparently was the real problem was a bios setting on the machine. There is a BIOS setting which says it will keep the terminal redirection agent active after kernel boot. Apparently on certain systems, Grub does not handle this being active very well. The instant I turn this setting off, the system boots up with out issue. Well, I hope this helps.
