94 Serial Port Console Redirection

Additional information for editing the grub.conf:

You may need to disable GRUB's graphical interface and use the text-based interface instead;

otherwise, the GRUB screen will not be displayed in BMU console redirection. To do so, comment out

the line starting with

splashimage

If you have multiple options in GRUB and you want all of them to start a console session through the

BMU serial connection, add

console=ttyS1,19200

to all options. The preceding example shows

console=ttyS0,19200

added to only the first option.

# NOTICE: You do not have a /boot partition. This means that

# all kernel and initrd paths are relative to /, e.g.

# kernel /boot/vmlinuz-version ro root=/dev/sdal

# initrd /boot/initrd-version.img
