Hi All,
I've being having some problems preparing a boot floppy which will allow
me to boot the hard disk kernel, by booting off the floppy.
(using FreeBSD 3.2-Release on a Gateway P150 16MB ram, 2.5GB IDE disk, 2
CDs, 1 floppy, vt320 off cuaa0, PNP modem;
everything else is working perfectly, ppp, printers, sound etc.)
At the moment, I've tried the following configuration (list of relevant
files and their contents from floppy/boot [contents are mirrored on hard
disk in /boot ]
{note: executables are the same as on the standard install floppy}
/boot.config
------------
-P
/boot/loader.rc
---------------
set currdev=disk1s2a
load /kernel
load -t userconfig_script /boot/kernel.config
autoboot 5
/boot/kernel.config
-------------------
pnp 1 0 os enable irq0 3 drq0 0 port0 0x2f8
pnp 2 0 os enable port0 0x220 irq0 5 drq0 1 drq1 5
pnp 2 1 os enable port0 0x200
At the moment what happens is... (sorry, don't know how to capture exact
text from boot process...)
boot: -P
keyboard found
|
FreeBSD blahdeblah
Loader blahblah jkh@cathair
Cannot find /kernel; press [ENTER] to boot immediately,
or any other key for prompt.
So normally, if the floppy is left alone, it will find /kernel on the hard
drive eventually, but won't load the kernel.config script, which means
that the modem and sound card won't be configured.
However, at this point, if I go to the loader prompt, it shows up as...
disk1s2a>
(as I put into loader.rc in the "set currdev=" command)
Then, at this point, if I execute the following commands...
load /kernel
load -t userconfig_script /boot/kernel.config
boot
All goes grand... everything loads as planned; only thing is I need to be
at the console to do this.
I can't fully understand the order in which things are happening... it
seems as if loader is on disk1s2a, but for whatever reason kind find
/kernel, and bombs out of loader.rc
Perhaps I'm missing something in boot.config?
Any advice or help at all would be very much appreciated!
