Using Windows 95 on the motherboard PI-P55TP4(XE). Details from manual: https://dlcdnets.asus.com/pub/ASUS/mb/sock7/4 … i_p55tp4xeg.zip

What a heck am I supposed to do? Sound card wants to use irq7 and gameport irq5 but printer port wants irq7 as well.

There are no jumpers on motherboard to disable COM and parallel and even if I disable parallel port from BIOS, the Win95 still detects parallel port and installs the drivers automatically and wants to use it... WTF??? Same goes for COM1 and COM2, as if I simply can't disable them.

Changing the socket doesn't help and from bios I can't find the option to have PNP off.

Try to disable onboard I/O (JP4). It should disable serial and parallel ports and free its resource.

1) VLSI SCAMP /286@20 /4M /CL-GD5422 /CMI8330
2) i420EX /486DX33 /16M /TGUI9440 /GUS+ALS100+MT32PI
3) i430FX /K6-2@400 /64M /Rage Pro PCI /ES1370+YMF718
4) i440BX /P!!!750 /256M /MX440 /SBLive!
5) iB75 /3470s /4G /HD7750 /HDA

It only disables the SMC chip which is for optional infrared module and didn't affect to anything else.

Can't you change irq manually for most sound cards in windows device manager?

If there is option in BIOS, you may try to enable 'PNP OS Installed', or something like 'Resource allocation by OS'.
Next, tick "disable in this hardware profile" in Windows device manager for COM and LPT ports.

What Sound card are You using? You may have to install PNP software for the sound card that lets you change irq, dma,
that's assuming it is a PNP card.

There is no reason why You shouldn't be able to use com ports, parallel, gameport, sound card, etc all at the same time.

I'm using this OPL4 card: https://retronn.de/imports/hwgal/hw_mozart_wa … _with_OPL4.html

I'm quite sure that my previous sound card (very noisy avance brand) didn't have these issues and the only other change in the system was enabling PS/2 mouse connector in the motherboard.
