I can help tomorrow when i get time since I got this working. Also you dont need to do swap IRQ. But you do need to go into the bios and change the parallel port so it doesn't use irq 7 and disable the parallel port. On those laptops the codec does sit on IRQ 11 but the legacy support is mapped to …

ok, in your autoexec.bat you need: SET BLASTER=A220 I5 D1 T4 C:\whatever folder\setupds /s (this initializes the card) In setupds can you change the IRQ mode from INTA# to S-IRQ ? That's what i put in my autoexec.bat file exactly. When i change from INTA# to S-IRQ, a lot more options are available …

Hi everyone ! I'm still trying to make my Tecra 8200 works under DOS. Here are some pictures and results, if you can help me understand (or state there is nothing to do at this point ;) ) : First, in the BIOS, IRQ 11 is settled for good for the PCI devices as the Yamaha YMF754B, you can't change …

for games that want irq 5 or 7 exclusively, the included ymfirq irq tool within the driver package addresses this issue, as you shouldn't use an irq swapping tool that's mean't for isa sound cards. :) Hi ! How do i use it ? When i type "ymfirq" it just accepts the IRQ 11 which is the one by default …
