I have installed 'Mavrick 10.9' on a 'HP Compaq 8200 Elite MT PC' with the following specifications :
HP Compaq 8200 Elite MT PC
CPU : Intel® Core i5-2400 @3.10GHz
RAM : 4 GB
Graphics : Intl® HD Graphics , DevID=0102 , VenID=8086
Audio : Realtek High Definition Adio , DevID=1c20 , VenID=8086
the installation was successful but I couldn't get audio working nor the graphics , the resolution is very low.
I need some help to get the Audio (speakers and Mic) to work and to enhance the resolution.
attached is a screenshot for the devices info.
