Sound Blaster Pro Test IRQ autodetect-how it wrks,IRQ sharing (Developers)

After playing more with resources I found that IRQ7 for ISA soundcard is some way unreliable even if not shared with anything (I disabled all USB controllers, LAN and LPT). It works better with IRQ5 (SBPro test autodetection and some other programs) but I have to disable LPT block after boot by writting to SuperIO chip. I cannot disable LPT in setup because otherwise USB controllers will take it and there's no other option to keep IRQ5 not used by PCI devices...

DOS gives me freedom to unlimited HW access.
