Default CDrom not detected in BIOS

I have old computer Compaq Deskpro PII 450 Mhz with integrated sound card Ess Audiodrive (not working), and CDrom (working). After I plug in PnP Sound Card ess1868 i finally got sound but I lost CDrom. Bios cannot detect my cdrom anymore. When I plug out my PNP sound card cdrom is detected just fine.

What can I do to solve my problem?

Thanks in advanced.

it sounds like a hardware conflict to me. try checking in device manager install both of them and hit scan for hardware changes, you may have to change the IRQ, memory, or I/O settings manually, but PnP should picl it up on it's own.

Onboard soundcard is disabled and I plug in ess1968 Isa PnP sound card. I also remove modem. When I plug in soundcard CDrom doesn't work again. (Bios cannot detect it, and also windows cannot detect cdrom). I try to manual install cdrom in windows and i have no success.
SOundcard is OK because it works but then i don't have cdrom.

I try all possible combination with jumpers and still nothing
CDrom only work if I remove soundcard.
