Ok, in the end I used another narrow SCSI disk (a ST39216N, the original 
disk is a ST1280N) that just worked.

As I don't have my Indys at hand currently, I followed "Installing 
without sysinst" ([1]) and installed NetBSD (NetBSD-daily/HEAD
/201808230630Z) on disk from my working diskless NetBSD installation - 
actually two times, as I didn't anticipate that one needs to reserve some 
space at the beginning of the disk for the SGI volume header as 
mentioned on [2]. :-D

[2]: https://www.netbsd.org/ports/sgimips/faq.html#sgivol

The result is working:

...apart from the MAC address patch that is not yet included in the ELF

I have not yet managed to configure the NVRAM vars in a way that would 
allow to just issue `boot` in the PROM monitor to boot the installed 
NetBSD. The kernel name and path is not actually hardcoded in 
`irisboot`, right? Because with an adapted default NVRAM config it 
doesn't work to just use `boot` like for IRIX:

```
>> printenv
netaddr=192.0.2.1
dbaud=9600
rbaud=1200
bootfile=dksc(0,1,8)irisboot
bootmode=c
diskless=0
volume=128
path=dksc(0,1,8)
cpufreq=33
gfx=dead (No keyboard)
console=d

>> boot

Again much thanks for making NetBSD on Indigo R3K possible again! If you 
need me to test future revisions, just let me know.
