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
