I got a Compaq Deskpro XL5133 (Pentium 1 133) and would like to add an ISA soundcard to the system. I disabled the integrated sound using the BIOS. Then I installed the sound card. However, the PC freezes after it finished counting the system memory. No visual error message, just 2 beeps meaning "general error". Putting the card into another slot doesn't help. The PC boots up properly when the card is removed. The Compaq BIOS provides an option for adding add-on cards, however I just don't understand how to use it. A previously installed PCI network card worked without any BIOS changes. The sound card worked fine in the computer it was installed before.
I hope you can help me!
