I am currently trying out having two different sound cards in my 486 retro build (MS-DOS 6.22). It seems to work fine (using different IRQ and DMA).

I would like to automate the config loading as much as possible and make it a part of my existing boot selection. Currently, I have a boot selection in config.sys and autoexec.bat with four different options (EM, EMC, XM, CM), where you can select expanded/extened/conventional memory and with or without CD.
Is it possible to extend to the boot selection with a followup question? In that question I would select which sound card to use. I am trying to avoid getting to many combinations by doing it as a separate step.
