if you have only a jumper for IO port 220 240 260 and so on. But no IRQ and HDMA and LDMA jumper blocks. Then you need to run DIAGNOSE /S but if you have all those jumper blocks then there is no need for DIAGNOSE /S.
I am aware that cards with jumper blocks (like cards with the CT1746, CT2501, and some CT2504) for the IO port, IRQs and DMAs do not need DIAGNOSE /S and only need the BLASTER variable set to the values of the jumpers.
What I have been trying to find out is the behaviour of applications on the CT1747 semi-PnP cards without DIAGNOSE /S being run to set the IRQ and DMAs with the BLASTER variable's parameters. Do apps behave strangely and can't find the card, hang, produce strange noise, play only FM music or does the card default to IRQ 5 and DMAs 1 and 5 on a cold boot? IIRC non-PnP Aztech Sound Galaxy cards default to 220/5/1/330/530 once the EEPROM jumper is set and no drivers are loaded (I have seen only one CT1747 card so far equipped with an EEPROM, the CT2760 rev. 3 AWE32, it doesn't appear to be present on the CT3900 AWE32 and other semi-PnP SB16 and AWE32 cards, and I also found out that that EEPROM was problematic and it was removed on the next AWE32 revision).
