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
