As said. If you execute this as root it should enable the card. You can pick 
the base address (the one JMPB0 is set to) with "-p 0x220|0x240". Default is 
0x200 if you don't specify one.

You can supply a configuration value yourself; you'd want the same value as 
the parameter to EEPROM.SYS in CONFIG.SYS under your DOS install. However, 
if you do not supply a a value the card will just be enabled using a default 
value (same default value DOS uses) and this should work fine assuming you 
have those default resources free/reserved.

so:

sudo ./eeprom
sudo modprobe snd-sb8 port=0x220 irq=5 dma8=1

or

sudo ./eeprom
sudo modprobe snd-sgalaxy sbport=0x220 wssport=0x530

Once you have the card set to wss mode (ie, have loaded snd-sgalaxy) you 
can't unload snd-sgalaxy again and start using snd-sb8; the card would have 
to be reset to SB mode first again.

After that sudo ./eeprom, the drivers should not only load but in fact work. 
Remember to increase/unmute the volumes in a mixer...

The program needs to talk to I/O ports and therefore needs root priviliges. 
It's generally a fairly bad idea to run root programs you haven't compiled 
yourself, but if compiling this userspace program is also a problem for you 
currently, there's a binary at:

http://members.home.nl/rene.herman/eeprom

was compiled on slackware 11.0, staticly linked.

If this still doesn't work you... I'm going to be sad.

Rene.
