I have 3 "older" PCI multi I/O sound cards which where only supported in WinXP (even then was plagued with random BSOD)
As a last ditch effort I've managed to get OSX 10.9 running only to see Mac won't accept/allow the hardware or drivers.
The last supported Mac drivers for these cards where for OS X 10.3
Question ... has there or is there a suitable release (with bootable installer) still available?
Or what is the oldest release available?
