My aboot configuration

I use aboot to boot my Alpha. It has a config file called /etc/aboot.conf. You can see my config below. Things worth noting are configs 0 and 8 (which are the ones I use, the other ones are only for rescue use.

Config 0 just boots my standard kernel, with an initrd containing my SCSI drivers.

Config 8 boot the same kernel, but with a serial console (that's how I've captured all the bootup messages).

To boot with a serial console, I just disconnect the keyboard/mouse, connect a serial cable to the top serial port, and boot the machine. In SRM I then give this command:

Digital AlphaPC 164 366 MHz Console V5.5-1, Jul 14 1999 12:37:45
>>>boot -flags 8


# NOTICE:  You have a /boot partition.  This means that
#          all kernel paths are relative to /boot/

8:1/vmlinuz-2.4.16 root=/dev/hda5 initrd=initrd-2.4.16.img console=ttyS0

To be able to login on the serial console, you need to start a getty on it as well. To start it at bootup, modify /etc/inittab. Here's the relevant bit from mine:
