Hi,
 
i am in trouble booting a DECstation 5000/125 with official=
 NetBSD 
1.4.2 ISO. At the moment Ultrix 4.3 (rel 44) is installed.
I read a lot of threads in the netbsd/pmax-ml, but couldn't find=
 
enough informations how to solve this problem. 
 
 
cnfg shows:
 
3: KNO2-BA DEC             v5.7                TCFO       (32 MB)=

mounting the cd with Ultrix  'mount -r -t cdfs /dev/rz4c /mnt'=
 e.g. 
and other varations ends in "Operation not supported"
 
i read about the 512byte <-> 2048byte problem, and my cdrom has=
 got a
jumper to switch between 512 <-> 2048, but then the cdr isn 
recognized by DEC/ultrix.
 
Then i read here and here a little with boot_xx9660(?) and 
installboot, but couldn't find a detailed=
 configuration/installation, 

i hope you can give me any hints or links etc where i can find 
something where i can detailed read what i have to do.
 
is it true that in combination with installboot i have to create=
 an 
extra iso, cant i use the official one ??
 
maybe i can find a floppy for the decstation, how to boot from=
 that ? 

fs on the floppy, etc.. ?
 
i am working at this problem for weeks now, but until yet without=
 
success 8-] 
 
Thanks!
