[Oslib-devel] diskdemo results (with DEBUG)

[Paul D. <du...@ho...>]

First, Luca said that on cvs vm86.c had changed.
I did not seems to be the case, so I manually removed the "offending" lines.

Replacing vm86_ to x_ calls, have made the floppy disk motor to spin. (At 
least first time
I tried). But then hangs there, without ever writing reset finished, so it 
must be
on the reset call.

I have made some changes, to remove warnings, and also to  comment out
the reading of a sector, keeping only the call to reset disk, and read disk
parameters.

Don't apply this blindly, just to show you! :

I tried to use X_calls with DL=0x80 (hard disk rather than floppy), but this 
didnt helped.
Hanging before writing reset finished.
