Eurohard OS9 Level 1 V2 - disk OK?
Posted: Sat Jan 14, 2017 12:55 am
Hi all,
Since getting hold of my CocoSDC, I've been messing around with some of the disk software from the archive on my Dragon 32 (64 + 6551) rather than using XRoar.
One thing I've noticed is that the Eurohard OS9 V2 system disk image in the archive doesn't seem to BOOT reliably on my real hardware via the CocoSDC. DragonData and NitrOS9 both fire up reliably, and being worried about my precious old hacked about drahon I've done some other hardware tests (Ram test routine for hi-32k, and SAM & CPU swaps) but to no avail...
I wonder if the disk image is a bit dodgy in a way that doesn't manifest in XRoar, or if it's some sort of CocoSDC thing. Would anyone else mind doing a test on real hardware with a CocoSDC?
To be as close to real DragonDos hardware booting, I'm selecting the OS9 v2 disk via SDRIVE or using SDCX, then switching to an ordinary 8k Superdos e6 disk rom in another SDC bank, then booting os9.
If anyone else can reproduce the fail, then I'll dump the version of Eurohard OS9 L1 V2 that I have on disk here and see if that improves things.
