Ok I didn't know about of that EXDOS modified rom. In that case you must assign also the H: disk to A:. It is the more important thing as if not the EGI insists on searching its system files on A: and hangs.

 Write "assign a: h:" an then "assign b: f:"(or the partition you want to manage) the very first lines of EXDOS.INI and leave all the following paths as in the original file.

But if your EP got instaled a HUN.rom or a BRD.rom, fman.egi will hang.....

To ensure that all is well, change the last line of EXDOS.INI " load \egi.sys\fman.egi" to "load \progs\icon.egi".

It then will jump directly to the demo app "icon editor".

We must wait for a programmer to fix that fman app.

I have none of those. I use a pure english system.

Some lame attempt after I wrote hw level emulation of boxsoft mouse interface in my web based EP128 emulator ("JSep"):

After the emulation starts wait for the EGI interface is shown then click onto the emulated screen of the Enterprise. The browser may ask if it's OK to grab the mouse cursor, you should click on OK etc then (you won't see the "PC" - well, or Mac, etc - mouse pointer anymore). After this, you should be able to use your mouse to control EGI more or less You can get your "normal" mouse pointer back with the ESC key (at least in firefox, maybe the same with Chrome, etc). Of course you need quite decent browser to use JSep in general, and especially the mouse emulation (forget IE ... any version!).

ASSIGN and some other commands original part of the EXDOS (version 0.3) but later removed because out of ROM space (version 1.0). Only available in IS-DOS.
The German EXDOS 1.3 got a 32K EPROM, with lot of unused ROM space. Later unknow Hungarian man putted back some of the removed commands.
In the EXDOS 1.4 I putted back all removed commands. Few months ago I uploaded test version.

Z80System I think you have the first quick modified version which only the FAT sector handling bug fixed.

But.....it works great! Every EP owner will want one of these Boxoft mouses....

(Only, in your  JSEP if you points to the extreme right you appear a little at the left... Few tweaks and it will do fine)

I guess it's fault of the mouse driver on the EP (mouse.xr) or the EGI itself, etc. Mouse interface at hardware level (what I emulate) only knowns about relative motion (it does not know anything about the "real" screen coordinates!), and the software on the EP calculates some real posiition of the pointer, so I can't fix that. As far as I can tell (however I can't check that ...) it would be the case on a real EP with boxsoft mouse and this software as well! Of course I can be wrong, but in theory this is how it works. However it would be great if someone can test this also happens with a real EP+mouse too, I am curious now. If it does not happen there, it's a quite odd situation and not so easy to find the bug then in JSep Thanks for the feedback!

lgb, you are too modest. Sure you find the bug soon as you did with the keyboard keys.

Ooop. But surely ISDOS will search for it on drive a:, so we are inside a vicious circle....
