SB live doesn't use IRQ5 it usually use shared IRQ9-11 and high IO port C-Exxx and SBemu software emulate legacy IRQ/IO ports. If you did some changes in HW config it may happen that real IRQ/IO has changed due to PnP mechanism and you have to reconfigure driver to know the real resources. I don't exactly know how it works but in my case I use Win98 with SB drivers too and it can be seen in autoexec.bat that SB driver reference some INI file from windows directory (i'm not at home PC now to be more specific) which tells to DOS driver the real resources. Again, IRQ5 is only virtual product of emulation. If you don't have another soundcard or LPT enabled at IRQ5 there shouldn't be conflict.

DOS gives me freedom to unlimited HW access.
