[rescue] Getting image on drive

I've got some SCSI2SD and other similar SCSI replacements. Without
working from a Sun 4 box, I'm trying to figure out if there is a way to
write an image for say Sun OS 3.5 (or 3.4.1)
onto an SD card that could be used to boot my Sun 3/110.

I've done something similar in the past, it was a 3/50 and a real SCSI
disk in my case.
Since my QIC drive is dead and it's hard to create and write SunOS 3.5's
UFS with modern systems, I decided for a netboot from my Solaris 11
server using a SunOS 3.5 tape image from sun3archive:
|
|||||1) sun3 uses tftp to download the 2nd stage bootloader so I placed
the ndboot.sun3.private from the distribution tape to /tftpboot
directory on the server and created a symlink based on my 3/50's MAC.

2) I setup nd daemon (https://github.com/senjan/ndd) on my server. disk
0 (nd0) was the miniroot from the distribution, disk 1 (nd1) was a giant
tar created from the rest of files from the distribution.

3) from 3/50's PROM I did "b le()" to boot the 2nd stage bootloader from
its LANCE ethernet controller. Once this was done, I boot the unix from
the miniroot with "le(0,0,0)vmunix".

4) Once in SunOS, I simply started the suninstall script to slice the
disk, then killed it, manually created file systems on the disk with
mkfs, filled /etc/fstab on the disk and untar distribution files from
/dev/nd1.

5) before reboot, I renamed /etc/ypbind to something else to prevent
SunOS hang on boot trying to bind a NIS server.

Unfortunately my old SCSI-1 disk failed soon so these days I'm running
my 3/50 diskless. It's actually pretty convenient because its disks are
just files on my server's ZFS so I can snapshot them and eventually
rollback if needed quite easily.

Thanks,
Jan

I've spent some time trying various remote boot options and haven't been
successful yet. I'm trying to do this as a starting point
to do remote boots of the Sun 2/120 machine I'm restoring. If anyone has
a process for doing it, would be very useful!
I'll be sure to get it documented and up on a web page and into
Archive.org...
I've got a bootable disk for my Sun 1/110 but I'm not sure how full of an
image it has on it. And that's also an SMD disk. To make matters
crazier, I've got a SMD->SCSI adapter device
(from a nice list member!) so ultimately I'm going to try to get an image
of some original/very-early Sun OS versions I can install there.
I don't have a MultiBus SCSI card yet (it's been on my list behind the Sun
2 kbd :-) ) .
