So a new day and brain with new thoughts and questions.

So I've managed to get one HD5 to work out of many, many attempts... I'm
trying to narrow it down... Why I managed to do it once, but have been
unable to do it since despite dozens of attempts.

So start from scratch.
Download a new copy of a Hd from the RPCEMu site.
Stick it in an emu install.
Run that install.
Obviously check Emu-Setting-Disabled is ticked (Is in all of mine)

Boot-Configure-Discs
Cd-ROMS set to 0
[Set]
Warning... [Continue]
Disc configuration [Set]

Open Disc configuration again
ADFS Discs
Select 2 
[Set]
Warning... [Continue]
[Set]

Excellent, that worked, but fly ointment time I'm afraid.

The HD5 operation will only work on RO 4.02 setups.
A 4.02 then softloading 4.39 fails, and 4.39 only fails.

So the answer for the time being is do it in a 4.02 setup, then upgrade to
4.39 afterwards.
This does work.

Re: [Rpcemu] Getting started with RPCEmu for Mac OS

 Thanks Francis.
 
 Try http://www.devrx.org/software/rpcemu/rpcemu-spoon-fjd-2010-09-27.zip.
 I've made the poduleroms loader skip files starting with '.', so it should
 skip  the .DS_Store file.
 
 This new version enables RPCEmu to get going. When I ran it, the Boot 
 sequence 
 was still compressed, but I got to the desktop OK after a 'Disk not 
 recognised' 
 error. Once there, I changed the filetype of HardDisc4 to 'Utility' and 
 double-clicked it. This unpacked the disc image, which I copied into the root 
 directory of the hard disc. I then configured RPCEmu to boot from HostFS as 
 instructed.
 
 
 After doing that, RPCEmu doesn't get to the desktop. The start-up screen 
 reads:
 
 RISC OS 24MB
 ARM 610 Processor
 RPCEmu Host filing system
 Error: Internal error: abort on data transfer at 00FBD00C (Error number 
 8002)
 
 Followed by the *-prompt and flashing cursor. Typing *desktop brings up the 
 desktop, but the Boot sequence clearly hasn't run, and everything is very 
 unreliable - running any applications will crash the system, and the sprites 
 are 
 corrupted.
 
 Any pointers as to what I'm doing wrong would be much appreciated. I've 
 attached 
 the error log below.

I've tried following the instructions at http://www.marutan.net/rpcemu/ro5.html 
to install RISC OS 5.17 and on my first attempt it didn't work either, although 
it failed for me in a different way:
After I've unpacked HardDisc4 and configured boot from hostfs with:
*configure filesystem hostfs
*configure boot
then after I reset with File-Reset RiscPC I get an error during boot: File 
,òflå,òflå,òflå,òflå,òflå,òflå,òflå' not found - see the screenshot at 
http://www.devrx.org/software/rpcemu/screenshot_ro_5_17.png.  If I press cancel 
in the error box then the same error is repeated.

I then changed the CPU Type to SA110 (it was previously on the default of 
ARM610) and reset the emulated RiscPC again, and after that RISC OS 5.17 booted 
up to the desktop without problems.

Chris, I would recommend changing the CPU type to SA110.  If that doesn't work 
then you could try a different version of RISC OS, e.g. 4.39 or 4.02.

Perhaps we should we change the default CPU type to SA110?  I don't want to do 
this unilaterally for the Mac version though, I think that the default should 
be the same across all host platforms.

Thanks,

Francis
