I am new to NetBSD, I've worked with OpenBSD for sometime
however it has not been compiled for SUN4u 64bit chips yet, 
so I am now going to try NetBSD for my sparc boxes.  Reading
the instalation notes it references the following;
under the source tree.

/instalation/
floppy/
sparc64 boot and instalation floppies

miniroot/
sparc64 miniroot file system image

/misc ect... .....

Instalation suggests doing a "dd" of miniroot.fs to my 
swap partion and booting from from that image, HOWEVER
I am unable to locate a miniroot.fs or floppyXX.fs file
anywhere.  I have looked on 15+ ftp distribution sites
and there is no such files

on all of the sites I've looked on the source tree is

/NetBSD-1.5/sparc64

INSTALL.html
INSTALL.more
INSTALL.ps
INSTALL.txt
binary/
/kernel/
/sets/

installation/
/misc/
/netboot/
/ramdisk/

I downloaded ramdisk.fs and "dd'ed" this into my swap file system 
and booted this "fs" image

I also "dd'ed" this into a new file system on a new partition I 
created. #newfs /dev/rdsk/c0t0d0s6  


I booted the system from an open boot

ok boot disk:b netbsd -s and also tried boot:g netbsd -s

both booted fine and scanned my system all looked well until

I got an error: 
wdOc DMA error reading fsbn 0 (wd0 bn 0 ; cn0 tn 0 sn 0), retrying
pciide0:0:0: lost interupt

"this repeats several times the from the output reads

wd0c: device timeout reading fsbn 0 (wd0 bn 0 ; cn0 tn 0 sn 0)
wd0: disk label read error
mountroot: trying msdos...
mountroot: trying cd9660...
mountroot: trying lfs...
mountroot: trying nfs...
mountroot: trying ffs...
no file system for wd0 (dev 0xc06)
cannot mount root, error = 79

"Then I'm prompted with the following"
root device (default wd0g):
dump device (default wd0b):
file system (default generic):
mountroot: trying msdos...
mountroot: trying cd9660...
mountroot: trying lfs...
mountroot: trying nfs...
mountroot: trying ffs...
no file system for wd0 (dev 0xc06)
cannot mount root, error = 79

I've changed all the variables to different root devices and different
dump devices and all the different file systems. Still no luck
the only difference is the the exit error code is a different #
cannot mount root, error = 6 
cannot mount root, error = 9 ect...

During inital boot scan I recognizes wd0 it tells me what channel is
on it's disk size in MB ect...

I am trying to install this on an UltarSparc 10 with 256MB Ram
current OS on the hard disk is Solaris 2.8 upgraded from Solaris 2.6
file system looks like this

c0t0d0s0 /
c0t0d0s1 /swap
c0t0d0s2 /backup (defined by solais)
c0t0d0s3 /usr
c0t0d0s4 /var
c0t0d0s5 /opt
c0t0d0s6 /new


Can some one please help !!!!!!!!!!!!!!!!! ugh ugh
