10BASE-T (8P8C), AUI (DA-15), 10BASE2 (BNC) Driver setup Some of the possible ISA I/O bases are 0x280, 0x300, 0x310, 0x320, 0x330, 0x340, 0x350. And IRQ 5, 7, 9, 10, 11, 12. The driver for OpenBSD, NetBSD and FreeBSD is "ep"; for Linux it is "eth". Patents 3c509B-C from 1996 specify the use of with a priority date of 1992-07-28. The patent describes a method where a data transfer counter triggers a threshold logic that generates an early indication or interrupt signal before the transfer is completed. The adapter also writes timing information into status registers such that a device driver can optimize for any latency.
