Hardwarova cast
1. Karta je PnP, presto je na ni jumper JP1 a JP2: OUTPUT-SPEAKER/LINE. Doporucuji nastavit ho spravne, nebot pri volbe SPEAKER a aktivnich beden zvukovka muze sumet (plati pro vsechny zvukovky s vystupnimi zesilovaci).
2. Jumpery JP3 a JP4 mohou byt pripajeny natvrdo na volbu 3D OFF. Nenamahejte se s jejich prepajovanim, protoze na karte tim padem nebude ani prislusny svab (plus hafo dalsich veci kolem), starajici se o 3D.

Softwarova cast
1. Karta je PnP - BIOS nebo kernel kartu na nejaka IRQ nastavi. Tato IRQ ale nejsou sdilena s PCI! To je dobre si uvedomit, rovnez durazne nedoporucuji rezervovat pro kartu vlastni IRQ volbou Legacy ISA v BIOSu. Tim dosahneme akorat toho, ze tyto IRQ zustanou neobsazena a zbytek systemu se bude chovat velmi zajimave.
2. Je dobre v novejsich BIOSech vypnout volbu

     PnP OS: No
   

   Muzeme se tim padem dozvedet z tabluky BIOSu pred bootem na cem je karta povesena a tak dale.
3. V Linuxovem jadre bychom meli mit ovladac pro karty OPL3SA2 a v radach 2.4 tez PnP ISA (oba bud jako moduly nebo v jadre).
4. Pokud mame oba ovladace v jadre, melo by jadro detekovat zvukovku jiz pri startu. Pokud mame modularni jadro, vyzkousime zavest rucne ovladac zvukovky:

     modprobe -v opl3sa2
   

5. Pokud vse chodi jak ma, pridame natahovani modulu do startovacich script, popr. upravime /etc/modules.conf napr. nasledovne:

     # Zvukova karta SM718 (?) - YMF7193-S
     alias sound-slot-0 opl3sa2
     options opl3sa2 io=0x370 mss_io=0x530 mpu_io=0x330 irq=5 dma=1 dma2=3
     options opl3 io=0x388
   

6. Pokud je neco blbe, popr. k dalsimu studiu doporucuji si precist dokumentaci v jadre: Documentation/sound/OPL3-SA2.
7. Pokud nemame PnP ISA modul, muzeme pouzit nastroje isapnp. Potom kartu inicializujeme v startovacich scriptech.
8. Pokud chceme pouzivat IDE, staci ho nastavit na karte nastrojem isapnp a jadru pri startu pomoci parametru napr.:

     ide3=0x168,0x36e,10
   

   rici, ze ma k dispozci dalsi IDE (spolehlive uchozeno i na 386 s 4xdisk 1xCD

Testovano v jadre 2.4.7. S jadrem 2.0 karta chodi budto jako emulace SB Pro/WSS nebo jako cs4232.
