Hi.

I'm trying to format a disk with the XDOS from abbuc contest but it fails.

When I type:

FM2

I got error 170

When I type

FM#

My computer hangs stuck.

Is there already an update of this DOS? If yes... where can I get that?

Thanks a lot

What is your drive configuration? Connect a standard ATARI drive directly to a standard ATARI computer and try it again! I tested all format commands with ATARI drives and they work.

well...

I was using Sio2USB for this and with the format command I see the error led flashing once.

That might be the issue. the CL# command does work fine with it, so there is not really a problem.

I tried the FM# command with SIO2USB (of course with a 130KB ATR) and it works - the computer doesn't hang stuck. You're right, the error LED flashes red. This is because SIO2USB marks unexecutable SIO commands always with the error LED - even if the error is intended by the programmer:

XDOS sends a Single Density PERCOM command to the SIO2USB, ignores the error return code and then sends a standard 1050 enhanced density format command, which is executed. This was the shortest way to implement all format commands - I didn't want to cross the 37 sectors size of DOS 2.5 for XDOS.
