If you have more than 1 mass storage, UniDOS is a must have, if you only have 1 mass storage, UniDOS still provides some useful features.  Eg: M4 vs UniDOS behaviour with RSXs vs changing the existing load, run etc... I like both ways, neither is wrong, UniDOS seems to be more compatible which I guess is why it is like that and if too many RSXs are added, it isn't always a good thing too for BASIC HIMEM.


As much as I'd like some additional features of UniDOS, even as it is, I wouldn't go back - because I am using multiple mass-storages at the same time.


Desperately want: more drive letters


a, b, c, d, f, g, h, i, m, r, s, t, u, x


a  & b - floppy drives & especially a for high compatibility for legacy software on any device
c - for compact flash
f - ftp mounted drive
g - gr8net mounted drive
h - harddisks
i - internet mounted drive

d - for mounted dsk
m & r - for ram drives
s - for sdcards
t - for a tape drive
u - native HxC USB

x - for x-mass


but of course we can assign any physical device to any letters we like from those which is awesome.

As soon as I add a PlayCity, it can take a while.

What would cause that?
If the PlayCity is attached, you read 0-bytes on a very large range of I/O ports (at least between #f800 and #ffff).

Maybe this is confusing some hardware detection routines?

UniDOS Scanning.
In a simple install, M4+XMem+YMem+X-Mass, it scans very fast.  As soon as I add a PlayCity, it can take a while.
Each DOS node is scanning for its supported hardware. So, what Prodatron said sounds very possible.

You may want to check which DOS node stalls with the PlayCity (M4 or X-Mass) and then determine if the detection code can be improved (I can't check on my own I don't have these hardware).

With a proper shell management you won't need any single drive letter apart for AMSDOS backward compatibility. 8)

Great! Where can we take a look at this shell? Download?

Hi Offset,


I've installed today UniDOS for a trial at ROM7. Attached boards are M4 and Nova NVRAM. Unidos says "warning: no NVRAM found".
The only other ROMs are the patched ParaDOS at ROM15.
What could be the issue why the NVRAM isn't detected?


(The Nova board works fine by poking value into it via BASIC).



...got it working

UniDOS 1.37 is available.


It is just a small fix improving AMSDOS compatibility in a very special use case triggered by Orgams with files smaller than 2K.
