Help: kernel on a floppy

Help: kernel on a floppy

Post by Cha » Tue, 09 Sep 1997 04:00:00



Hi,

Could someone tell me essentially how to make a custom
boot floppy.
I tried a
dd if=/kernel of=/dev/rfd0

I tried booting off from the floppy, but nothing happened.
Essentially, what I'm trying to do is to boot off my
floppy and hopefully tell it to load FreeBSD off my HD
(my /dev/wd0a partition)
Why?
I've done something similar with Linux
and found out that if I boot from my floppy, I could
actually mount my primary dos (actually win95) partition
[not an extended partition]
Now how do I do that in FreeBSD.

(Of course, the other reason I want to boot off a
floppy and specify my root partition is because I may
have more than one kernel of my preferred settings)

thx,
Henry Chan

I have recently posted a longish description of how to do this, and...

...i've also mentioned there why you don't need/want to do this at all
with FreeBSD.  Just use a boot selector for the choices.  You can also
boot as many alternate kernels or alternate partitions as you like
(although only from the very first FreeBSD slice aka. fdisk
partition).

Just use DejaNews if you're interested in seeing it.

1. Help: Kernel panic during the installation of floppies

Dear Linux Experts,

I am trying to install Linux for a while. I am using a Seagate
ST01 SCSI controller, which is as far as understan a supported board.
However, during the installation process, I am getting this message
and the system halts:

Kernel Panic
SCSI: Unsupported message byte xxx received.
In swap task, not syncing.

(xxx=128 or 111)

This message is produced during the installation of different floppies
in every trial.

Thanks in advance...
