OK, I will try that tomrrow (or rather later today).

OK, now it worked, but as I haven't configured a filesystem for it yet,
I didn't get a root mounted.

OK.

OK, I see.

No, you're right, it doesn't.

I also had to configure the screen mode to an 8-bit one. In a 4-bit one,
it told me that it was lower than 8-bit and just hung. The modes I have
been using are mode 35 and 36.

Dmesg is something like:

This was as far as I got as I don't have any boxes that respond to mount
requests. I do have an ISDN router set up as a DHCP server, but nothing
else.

BTW, that reminds me. Is it possible to have the ISDN route provide the
IP address and then mount the root and swap from my NetBSD/sparc 1.4
box?
Also, are there any particular things to your setup of booting NetBSD
over the network? I didn't find any information that was relevant to
either arm32 or arm26.

A couple of other things about the probe above:
1) The internal ST-506 drive does not seem to have been found.
2) The IDE Interface in slot 2 is an HCCS one.
3) The card in slot 3 is an AKA-30 SCSI card with a PowerROM from Partis
   Computing. It does not seem like it works on pre-Risc PC computers,
   so this is something I will ask Partis about.

The good news here is that the R140 seems to act well, and now I need to
get the filesystems exported from my NetBSD/sparc box, and possibly
compile my own kernel (the cross-compiler is building as I speak).

I am also downloading the latest arm26 binary snapshot, and will try to
get this working tomorrow.

Thanks for your help so far!
