I'm posting this for a friend whose Usenet access is temporarily not.

Hello. I've just compiled Minix 1.2 on a 386 AT-clone ("Fountain 386")
and lo and behold,

Unrecoverable disk error on device 2/1.
Disk in drive 0 is not root file system
panic, etc...

I managed to fix it - in kernel/floppy.c, in fdc_results(), in this area:

if ((status & CTL_BUSY) == 0) return (OK);
if ((status & (MASTER | DIRECTION)) = CTL_ACCEPTING) return (OK);
if ((status & DIRECTION) == 0) return (ERR_STATUS);

I inserted the middle line up there.
What I would like to know, since I don't have diddly documentation on the
floppy controller, is, is that a correct kind of thing to do? It was just
an educated guess and I have no idea why it works...

And has anybody else had this problem?
