One thing that has made it better is passing a bit delay down to elink_idseq, that is: > void > elink_idseq(u_char p, void (*bit_delay)(void)) > { > register int i; > register u_char c; > > c = 0xff; > for (i = 255; i; i--) { > (*bit_delay)(); > outb(ELINK_ID_PORT, c); > if (c & 0x80) { > c <<= 1; I haven't bothered committing this since it still fails 1 out of 6 times. Without this it fails 1 out of 3 times. If it logically makes sense that a delay is needed here (I don't have any docs) someone might add it.
