Chapter 3: Troubleshooting

For Windows 2003:

Enable Console Redirection in BIOS, and set it to COM 2 (or COM B)

Modify boot.ini in C:\. Boot.ini is a hidden ﬁle. Below is an example of boot.ini

[boot loader] redirect=com2 redirectbaudrate=19200 timeout=30 default=multi(0)di

sk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)parti

tion(1)\WINDOWS=”Windows Server 2003, Standard” / fastdetect /redirect

For Linux:

1. BIOS POST:

(i) Enable “Console Redirection” in BIOS Setup. For example, COM2 /

19.2Kbps / 8N1

(ii) Disable “Enable Console Redirection after POST” in BIOS setup.

2. BOOT LOADER:

(i) For GRUB, add the following TWO lines into /boot/grub/grub.conf, but

comment out “splashimage=(hd0,0)/grub/splash.xpm.gz”

serial --unit=1 --speed=19200 --word=8 --parity=no --stop=1

terminal --timeout=10 serial console

#splashimage=(hd0,0)/grub/splash.xpm.gz

(ii) Then add “serial console=ttyS1,19200n8” to the end of kernel /vmlinuz in

/boot/grub/grub.conf.

For example:

kernel /vmlinuz-2.6.5-1.358smp ro root=LABEL=/ rhgb quiet serial

console=ttyS1,19200n8

This will result in all boot messages to be output to console ttyS1, and you will

not see all these boot messages at the local console until login message promt

up.

c) Under LINUX OS:

(i) Add the following line into /etc/inittab.

s0:2345:respawn:/sbin/agetty ttyS1 19200

(ii) Edit /etc/securetty and add ttyS1
