*******************************************************
*****ONLY FOR PEOPLE NOT USING THE GUSPNP DRIVER*******
*******************************************************
Can anyone who has the gus pnp driver working on 2.2 please send it
to Seppo....
If you are running FreeBSD-2.2 , it is possible to init the gus pnp on
DOS and then soft boot to FreeBSD and use the old GUS driver .
The requirements to do this are:
1. You have to be able to initialize properly the GUS PnP on DOS and
this means you got to have a motherboard with PnP support.
You must use dma channels 1 , 2, or 3 on DOS. Your configuration
for DOS must match the configuration on FreeBSD.
Your <kernel> configuration file should look like this:
controller snd0
device gus0 at isa? port 0x220 irq 11 drq 1 flags 0x3 vector gusintr
After proper initialization on DOS you must soft boot to FreeBSD
in order to preserved the initialization state on the GUS PnP.
If you power-cyle the machine, the GUS PnP will forget its
activation and configuration. This is a correct behavior
for PnP devices.
--------
Note:
At work, I failed to recognized my GUS PNP on FreeBSD with the old
sound driver because the motherboard did not have proper PnP support.
--------
2. With the *old* sound driver on FreeBSD-2.2 , modify in
gus_wave.c/gus_wave_init:
{
/*
* It has the digital ASIC so the card is at least v3.4.
* Next try to detect the true model.
*/
val = inb (u_MixSelect);
/*
* Value 255 means pre-3.7 which don't have mixer.
* Values 5 thru 9 mean v3.7 which has a ICS2101 mixer.
* 10 and above is GUS MAX which has the CS4231 codec/mixer.
*
*/
val = 66;
^^^^^^^^^^^^^
Add the above line
This simple patch will force the sound driver to say that the GUS PnP
is a GUS MAX.
If you don't have proper PnP support on your motherboard just
simply wait for the guspnp driver to be released for FreeBSD-2.2-current
Hope this helps,
Amancio

You mean if you use the new pnp driver and FreeBSD 2.1?
Can I configure gus pnp in DOS, power down and run it in FreeBSD
2.2-current at this moment?
