The way I interpret the docs for the ESS cards, it looks as though it emulates an SB16, but has more to it. As quoted from the document you referenced: "ESS builds cards that implement a superset of SB16. They are often capable of full duplex, but my driver does not support them other than in full duplex emulation." Actually, the kernel config line you have above works for both my ISA AWE64 (value) as well as my SB16 (value), with the exception of the "flags" at the end. I have mine set to 0x15. -Otter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
