Riscstation ROS4.03 ROMS in RiscPC?

these ROMs installed, all that appears on screen is a cursor at top-
left.
My question is then - are these ROMs intrinsically unsuited to
installation in a RiscPC or are they duff? Also, if the former, why
not?

As it is running on hardware that is different to both the Risc PC and
the A7000. I'm not surprised it does not work.

Never heard of 4.03 ROMs for a RPC so I'd guess they are different.

They are completely unsuitable. And for the same reason you can't use
an Iyonix ROM in a RiscPC; the hardware's different, how it is
initialised is different, and how to drive it is different.

Thanks for a clear, concise answer - at the time I think I was
a thinkin' A7000. For some reason, Riscstation never clicked.

versions for RiscPC-Kinetic, Riscstation and Mico. Presumably the
Kinetic-targetted version was closest to the "vanilla" RPC/A7000 ROM
of the time, but I don't know if even that would work in a non-Kinetic
RiscPC.
AIUI the next ROM release - 4.39 - is hardware-indifferent between
these machines (and the A7000 / A7000+ and perhaps the Omega, if you
have the right firmware).

The Kinetic version of 4.03 would work without a Kinetic Card but it had to
be replaced with a StrongARM card, there was a bug that stopped it from
working with a 610 or 710 card. This bug was fixed in 'Kinetic 4.04'
I'm not sure what the Omega shipped with 4.02/4.03 or 4.04 I think.
I know it tried to simulate a RiscPC so maybe 4.02!
After 4.04 ...

Does it flash? If you get a flashing cursor on the 'wrong' hardware you're
doing extremely well. It may be waiting for an IDE drive on an interface
that doesn't exist. Did you do a Delete-power-on reset? Try booting with
Shift and keypad-* held down. If you can get it to a command line you can
probably do something about fixing some of the broken bits (eg unplugging
IDEFS).
It appears to have all the modules necessary to run on a RiscPC:

Though of course some of those may be Riscstation custom versions.
Give it a try... you have nothing to lose.

Yes, I think so

Yes, that's what I suspected.

I did umpteen different types of reset till my fingers were sore
and also tried leaving it for about 15mins to see if it would
eventually go to the desktop. This is why I asked if the ROMs
were /intrinsically/ unsuited to a RiscPC - RK thinks they are.

That's what I had hoped.

Seen that.

The one that sticks out is RSSupport - this could be the culprit.
If I knew it's place in the module order, I could perhaps unplug
the correspondingly numbered module in a working OS and then
/without/ doing a Delete-power-on, swap the ROMs and....

Maybe I'll try it again sometime - maybe with an IDEFS i/face
connected. Thanks for your thoughts.

The other thing that's been especially useful on NCs when they're trying to
run broken software on boot from ROM is Alt-Break. It probably won't help
modules in supervisor mode, but worth a try.

That could be. I suspect you might get something running by unplugging
various modules - I've done this on NCs too. But in that case I did at
least get a command line to do it.

I doubt the RS IDE interface bears much similarity with Simtec's podule
interfaces, so I doubt this will work. But if you had a podule with flash,
you might be able to flash a module which unplugs the suspect modules at
boot.
It's still fairly unlikely to work (the hardware is indeed different in a
few ways). But never say never.

If anything, the CPU and I2C bringup, along with some other fairly
fundamental things, are different. Things are changed /before/ the
module chain is initialised. It's never going to work.
I have a long list of technical details and driver sources that need
tidying up and releasing for the RiscStation; perhaps so somebody can
port RO5 to it if they're really bored :)

It's a version of 4.03.
