Sorry, Bruce, no joy with the sio.c patches on my Compaq LTE/Elite 4/75. I futzed around most of the night trying to get the blasted thing to find sio[01], to no avail. Admittedly, sio1 is on a pccard modem, so I put that on the back burner for now, but I am peeved that I can't get sio0 to probe correctly either. I'm willing to work this one as long as you have the patience to guide me, but I admit that I'm straining for clues. My base system is 2-2-960801-SNAP. I pulled sio.c from -current and folded that it, no joy. I (manually) applied the sio.c patches you mentioned, no joy. I munged through the code and applied 'DELAY(10000)' to nearly every spot in the source that had the /* EXTRA DELAY ? */ comment, no joy. Where do I start to get this one hammered out? ...sjs... ---------- > From: Steve Sims <SimsS@Infi.Net> > To: Bruce Evans <bde@zeta.org.au>; freebsd-hackers@FreeBSD.org; housley@pr-comm.com > Subject: Re: Problem with sio0 > Date: Monday, September 09, 1996 8:24 AM > > Bruce - is this a coincidence, or WHAT?
