You are most welcome -- BTW:  the first name is Clement, my last is Cole and my friends call me Clem.

One thing to remember... when woring with older versions of UNIX its not a good idea to be modify in the a partition that is live.   Later versions were better about keeping the buffering system of your way.

Ken wrote the standalone tools for V7 so you do those sort of low level things from it.   

Best wishes.

Ah I gather you are running on rp0 (ie it's mounted as root).

Do the dd from the standalone system or boot from an rk05

I am unable to boot from the RP06 disk that I installed into the boot block onto via:
dd if=/usr/mdec/hpuboot of=/dev/rp0 count=1

​ Doing this from memory as couple of issues:

1.) do an ls -l of /dev/*rp*  you need to use the raw (character) driver not the blocked driver

2.) I believe the hp/rp driver is partitioned.   Make sure you use the proper partition.​

Clem,

I tried it with the raw device and partition 0. Here are the devices and my approach:

# ls /dev/*rp*
/dev/rp0
/dev/rp3
/dev/rrp0
/dev/rrp3

# /etc/mount /dev/rp3 /usr
# dd if=/usr/mdec/hpuboot of=/dev/rrp0 count=1 conv=sync
0+1 records in
1+0 records out
or
# dd if=/usr/mdec/hpuboot of=/dev/rrp0 count=1
0+1 records in
0+1 records out

# sync
# sync
# sync
CTRL-E
