I swapped the 4GB DOM for a 2GB one formatted and used on another system. Filecore partition scheme. It too shows up as a 1.5GB Filecore partition and a 417MB "Unusuable" bit. Does look like there's a bug somewhere - may not be PM because *free still shows rubbish (4GB free on a 2GB DOM...) - ugh!

Why are you running it under Aemulor? It's written to run natively on all OS versions.

More to the point, how did it detect Simtec on an A9? I've never seen an A9, but thought it was 32bit only without a Podule slot, in which case where is IDEFS coming from? Does the A9 use IDEFS for its filesystem, if so PM has possibly misdetected - I'll need to see the debug log.

IanJeffray wrote: Wed Apr 19, 2023 I don't know what's going on with that DOM. *FREE shows 4GB free, 2.8GB used. But it's only a 4GB DOM... so... wrong and wrong!
But it is actually completely empty so ... whuu?
(Was formatted with Simtec IDETool btw)

IDETool possibly exceeded a filesystem limit when it formatted the drive and a value wrapped? From my reverse engineering, I believe the limits are 512MB for each partition and 4GB for the physical drive. I don't have a Simtec to test, but HCCS lets you exceed it's limits without any checks or restrictions and they're essentially identical.

IanJeffray wrote: Wed Apr 19, 2023 EDIT: I deleted the DOM partition with PM and the A9 "went mad" and ultimately locked up, but it did delete the partition it seems (after a reset)

At a guess IDEFS or FileCore hung when the filesystem restarted. As the partition was deleted, PM had finished its disc writes and then attempted to restart IDEFS and its Filer. I can add some additional debug output in the next build - which supports Reporter so you can watch what's going on real-time.

IanJeffray wrote: Wed Apr 19, 2023 EDIT2: I then asked PM to create me a new partition, whole disk sized. This is what it did...

What was the size of the unallocated area before you formatted it and what MB did it show as "max" in the format dialogue?

IanJeffray wrote: Wed Apr 19, 2023 Wuuuuuh? Why the "Unusable" bit? Why wasn't it the size I asked for? Why is free space still greater than the partition size?

That's correct. It's formatted as a "full-disc" FileCore drive so the unused space beyond the FileCore area is literally unusable as there's no partition table.

IanJeffray wrote: Wed Apr 19, 2023 Maybe these are all A9/Aemulor issues.

EDIT3: I repeated the initialise / create partition actions on the DOM - same behaviour/result. Fun.

Take Aemulor out of the equation and try formatting one of the DOM's natively with PM. You could also repeating the test on something modern running RO5 (RiscPC or Pi via USB adapter) and compare the results to confirm if there's something odd occurring on the A9.

RISC OS 4.42 throws an error saying the BASICPM module isn't 32bit compatible. Didn't investigate further.

My point is that there should have been no reason for it to create an "Unusable bit", particularly when told to use the full disc. 1.3GB of unusable for no reason is just broken behaviour.

I've no interest in RO5, nor any idea how one might somehow rig a Simtec IDE interface on to a Pi.

These DOMs are those which I use on 'all' other IDE interfaces/machines just fine - I trust the behaviour of the DOM.

This is RISC OS 4.42. There's no 512MB limit anywhere. I've repeated this behaviour now with a 2GB DOM. Perhaps this Simtec IDEFS is just fubar.

It's BASIC is too out of date so PM tried to load the bundled one for RO3.1. You could try commenting out the RMLoad line, but I suspect it might fail miserably.

Oh well, that probably rules out RO4 and 6 support without some bespoke changes.

It doesn't create an "Unusable bit", it just marks the end of the disc as such to prevent you trying to create a partition. The question is what size is the unallocated area when the drive is initialised and what is the "max" MB it shows when you try to format it. PM either capped the size to a filesystem limit, or something went horribly wrong. If you Initialise the drive and then grab a debug log, it might help.

IanJeffray wrote: Thu Apr 20, 2023 I've no interest in RO5, nor any idea how one might somehow rig a Simtec IDE interface on to a Pi.

I meant format the DOM on a RO5 machine natively - no need for the Simtec, a USB-IDE adapter on a Pi would suffice. Somewhat academic if you don't have anything modern though.

The Simtec filesystem has internal limits as it doesn't support LBA addressing. The CHS reported by the drive would probably be the limit in this case.

The is probably a daft question, but how have you got a Simtec on an A9 running a 32bit OS? All the Simtec Modules I've looked at so far are 26bit...or do you have an IDEFS Podule I've not accounted for?

EDIT: I've just checked my notes. Simtec is CHS addressing only with a limit of 2^32-1 sectors. It doesn't require partition alignment to cylinders, so an initialised drive should set "max" to the full drive size in MB - if you could confirm. I'm also assuming the drives are not 512e/4Kn - the debug log will confirm.

What on earth do needs something more recent than even RISC OS Select 4.39? Boggle. Are you really loading a 3.1 version of BASIC even on a RISC OS 4.39 machine?!

I commented out the RmEnsure line and that causes PM to just lock up -- doesn't load, but just "gets stuck". Yuk. Back to Aemulor...

I noted this previously... the A9's native FS is IDEFS - the Simtec IDEFS, and as such obviously has to therefore be 32bit.

ReInit IDEFS

Posted: **Thu Apr 20, 2023**

The partition scheme was still showing as "Filecore" after partitioning to "Simtec" with PM, so I initialised and partitioned the disc with IDETool, which created what PM (apparently errantly) shows like this..

Here's the debug log from when loading that session of PM...
