- * We get eeprom data from the id_port given an offset into the

- * the cards; they enter the ID_CMD state where they will accept
- * command requests. 0x80-0xbf loads the eeprom data.  We then
- * read the port 16 times and with every read; the cards check
- * for contention (ie: if one card writes a 0 bit and another
- * writes a 1 bit then the host sees a 0. At the end of the cycle;
- * each card compares the data on the bus; if there is a difference
- * then that card goes into ID_WAIT state again). In the meantime;
- * one bit of data is returned in the AX register which is conveniently
- * returned to us by bus_space_read_1().  Hence; we read 16 times getting one
- * bit of data with each read.
- *
- * NOTE: the caller must provide an i/o handle for ELINK_ID_PORT!
