Re: vfs_mountroot: can't open root device / cannot mount root, error = 6

Adding part of my original email back into this thread to address your point:

<part of original email>
I'm creating my Compact Flash disk image (for my 256MB SanDisk) as follows:

# dd if=/dev/zero of=netbsd.img bs=512 count=500400
500400+0 records in
500400+0 records out
256204800 bytes transferred in 6.666 secs (38434563 bytes/sec)

# vnconfig vnd0 netbsd.img

# fdisk -ua0 vnd0
....
....

</part of original email>

The vnd is configured to access the file image (netbsd.img in this case) I set 
up on my workstation before dd'ing it to the compact flash (where the CF ends 
up being wd0 on my other computer).  wd0 at the time I run the installboot 
command is my workstations hard disk.  I surely don't want to be messing around 
with that, right?  

Thanks,
Bill

What lives on wd0 and what lives in the vnd?

You're putting the boot code on the vnd, which is just a file on the
filesystem, so I'm guessing the bootloader couldn't find the
second-stage boot stuff.
