Hello,

I have my system configured with Linux and DOS partitions, with LILO as
the boot manager.

When I boot DOS, my soundcard works great. When I boot Linux, my
soundcard also works great.

But if I boot Linux, then reboot to DOS, when I launch MS Windows I get
an error message about the MIDI port setting not being correct and no
sound is generated from any of my applications.

Has anyone seen this problem before? Any help would be appreciated.

Thanks,
Scott

No... But, you are probably doing a soft re-boot (cntl-alt-del). If you
did a hard reboot (re-set button or cycle the power) The sound card will
probably run right. Linux is probably doing some software setting on your
card, and doesn't put it back the way it found it when you quit.

Yes, I've seen this problem as well. As Greg already pointed out in his mail,
the difference is between doing a 'soft' reset and a 'hard' reset. When doing
a 'soft' reset from linux (reboot command), and starting DOS, one of the
drivers which is installed during config.sys processing gives an error-message.
I haven't done any further investigating though.

regards,

AKr

I also have this problem with my SB16. When I quit Linux and reboot to DOS
to play DOOM (why else?) then Doom craps out complaining. Trying to use
vplay etc complain about the interrupt (IRQ) not being correct. Oh well.

A hard boot (reset button) restores things to working status.

FWIW: I use loadlin 1.4 (hmm, haven't tried with loadlin1.5 and kernel 1.1.49
yet, but I don't suppose it makes any difference).

Just a minor annoyance I'm happy to live with :-)

Check this out, I am having exactly the opposite problem. My sound card wont
work when I first power up and start Linux. I have to boot under DOS and
load the DOS SB16 driver, then warm boot back to Linux for the sound
card to work. Any ideas on this one?

Thanks

Most of the current soundcards have some kind of software configuration
for IRQ and DMA setings. If you use different settings with Linux than
with DOS/Windows, this may cause trouble. Some cards don't accept
new parameters before complete reset (power off/power on). There are no
problems as long as the DOS and Linux settings are the same.

Have you compiled the sound driver with support for SB16. The plain SB
driver doesn't contain code which initializes mixer and sets values to
some config registers. And the card won't work if these registers are
not initialized.

It's pretty common, I think, for multi-OS systems. When I soft-boot after
halting Solaris, the com1 is hosed for the mouse in Linux and DOS. If I
soft boot after running X in Linux, the video is hosed for Solaris and
Windows graphics. If I soft boot after running Windows sound, the audio
card (GUS) is hosed for Linux (it's always hosed for Solaris :).

Hard resets fix everything, except the com1 problem for the mouse after
halting Solaris. That requires a power off to fix.
