IRQ 5 is usually the most-free port; 7 is for LPT1, which can use EPP or ECP. If the printer port is using ECP, then that adds use of a DMA channel, usually 1 or 3.
Yeah I have disabled lpt in bios, there is disable option in my bios.

A DVD DRIVE using IRQ5 would be weird; IDE controllers usually use one of IRQ 14, 15, 11, or 10. Do you have an ISA DVD decoder card?
No It's just a regular CD-ROM drive from the era, for some reason whenever I use IRQ5 MSCDEX no longer finds the drive. On the ct4520: as soon as I plugged the cd audio cable to the card, MSCDEX would no longer be detected and the sound card wouldn't work either(it was on irq10), but audio cd would play on the speakers, that means the cable itself worked. I only have the isa nic and sound board, graphics are pci and there is ide to cf instead the vintage hdd of course.
Check all your non-PnP cards' jumpers, and if you have other PnP cards make sure you have only one PNP manager, like Creative's CTCM/CTCU or a USRobotics' own configuration utility whose name escapes me.
IRQs aren't the only issue; DMA can be one (but often that results in NMIs or reboots).
Yeah dma number is set to 1, I installed the driver and I was able to play nukem2 for a while now (used to freeze as soon as game started) I also played keen6 and kdreams no freezes there either, whenever the driver resolved the problem or I'm just lucky, I don't know.
This card is sure noisy, makes all kinds of whirling and hissing noises, most noticable when it's not playing anything and it's supposed to be quiet, awe64 did the same, but when I turned the volume down, it stopped, but here it's still pretty audible with volume wheel set to low. Is that just my card or anyone else using ct1600 has the same issue?
