Hello
I just tested the DOS game Starfire v1.4 both shareware and registered versions and When I use the ET4000 ISA I get a black screen after selecting the sound card.
The game works without any issue with the Trident 8900 ISA card.
My configuration is: MR 386 DX (I also tested 386 SX machines).
4 mb RAM, DOS 5.0. Here is the shareware version 1.4 of the game.
