Microphone Boost option

[Ark]

Hi All!

I am trying to find the information what cheap sound cards support "MIC
Boost" option. I use IBM Intellistation. The microphone input is very
weak, I bought cheap AOpen Cobra AW850 sound card and found the option
is not supported in this card.

Could you give me an advice what cards do support the "Microphone
boost" option?

Any advices will be greatly appreciated.

Thank you.
