[Oslib-devel] IRQ0 (int 0x40) calls int 28 (0x1c) cause bugs with floppy

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

Part of the problem with floppy access, is that it need the timer.
Most probably, to be able to abandon, if floppy disk access don't
work within a reasonable delay.

In DOS, you're not supposed to chain directly int08 (IRQ0) to have your 
program
be called at each tick, but to chain on INT 28 (0x1C).
Now, that's a bit special, because, we have to reflect 0x40 (IRQ0) and INT 
0x1C,
that is called from inside the reflected 0x40. Which seems to cause an 
error.

I'll try to send you the log in an other message, I just wanted to avoid 
Luca
to search too much.
