4.4 USB/IRQ problem revisited...I Can't assign IRQ in BIOS!

4.4 USB/IRQ problem revisited...I Can't assign IRQ in BIOS!

Post by Jason Gable » Wed, 09 Jan 2002 03:13:35



I have a Sony Vaio R505 which has a BIOS configuration utility which
leaves the R505 as configurable as a brick.  So, I have not been able to
get passed the 4.4R boot problem, save that I was able to compile a 4.4R
kernel from source on my 4.3R system and use it with the now well-known
modifications to /boot/loader.conf and the 4.4R kernel came up nicely.
However, running a 4.4R kernel on a 4.3R system presents its own set of
problems that I'd rather avoid.   So even though I can't configure the
BIOS I can modify loader.conf... this gave me an idea...

So, what I'd like to do is to edit the /boot contents of the kern.flp
image.  I have written it to a floppy and after reading some manpages
and studying the structure and contents of /boot on my harddrive, I
tried to modify the floppy's /boot contents.  However, I have not been
successful in getting the kernel on kern.flp to boot with the
loader.conf modifications to hw.pcic which get around the USB IRQ
conflict problem.  Can anyone tell me how to get the kern.flp loader to
include that information?  Isn't it just kernel config stuff? (I.e. like
you do when

You can simply set hw.pcic at the loader prompt. Simply when loader
has been loaded you hit the space bar and get the ok> prompt.
Here you can do
set hw.pcic=0 or whatever and then boot.
/boot/loader is a very flexible tool, it has many functionalities similar
to those of grub.

Are you absoposilutely sure it's a USB/IRQ thing?  While my "experimental"
system [the one I experiment on] is very different from yours, I couldn't get
FBSD4.4-R to load for anything.  I did the USB IRQ thing, and it didn't help at
all.  My problem was an unneeded USRobotics PCI modem card.  Once I pulled it
out of the system, the install stopped* at the hardware probe during
/stand/sysinstall.

Just a thought.
