-         *
-         * a) Clock Conversion Factor
-         *
-         *    This is a representation of the input
-         *    crystal clock frequency going into the
-         *    ESP on this machine.  Any operation whose
-         *    timing is longer than 400ns depends on this
-         *    value being correct.  For example, you'll
-         *    get blips for arbitration/selection during
-         *    high load or with multiple targets if this
-         *    is not set correctly.
-         *
-         * b) Selection Time-Out
-         *
-         *    The ESP isn't very bright and will arbitrate
-         *    for the bus and try to select a target
-         *    forever if you let it.  This value tells
-         *    the ESP when it has taken too long to
-         *    negotiate and that it should interrupt
-         *    the CPU so we can see what happened.
-         *    The value is computed as follows (from
-         *    NCR/Symbios chip docs).
-         *
-         *          (Time Out Period) *  (Input Clock)
-         *    STO = ----------------------------------
-         *          (8192) * (Clock Conversion Factor)
-         *
-         *    You usually want the time out period to be
-         *    around 250ms, I think we'll set it a little
-         *    bit higher to account for fully loaded SCSI
-         *    bus's and slow devices that don't respond so
-         *    quickly to selection attempts. (yeah, I know
-         *    this is out of spec. but there is a lot of
-         *    buggy pieces of firmware out there so bite me)
-         *
-         * c) Imperical constants for synchronous offset
-         *    and transfer period register values
-         *
-         *    This entails the smallest and largest sync
-         *    period we could ever handle on this ESP.

- *
- * 1) Figure out how to make a cleaner merge with the sparc driver with regard

- * 2) Make as few routines required outside the generic driver. A lot of the

- * I've been wondering what this is supposed to do, for some time. Talking 
- * to Allen Briggs: These machines have an extra register someplace where the
- * DRQ pin of the ESP can be monitored. That isn't useful for determining 
- * anything else (such as reselect interrupt or other magic) though. 
- * Maybe make the semantics should be changed like 
- * if (esp->current_SC)
- *      ... check DRQ flag ...
- * else 
- *      ... disconnected, check pending VIA interrupt ...
- *
- * There's a problem with using the dabf flag or mac_irq_pending() here: both
- * seem to return 1 even though no interrupt is currently pending, resulting
- * in esp_exec_cmd() holding off the next command, and possibly infinite loops
- * in esp_intr(). 
- * Short term fix: just use esp_status & ESP_STAT_INTR here, as long as we
- * use simple PIO. The DRQ status will be important when implementing pseudo
- * DMA mode (set up ESP transfer count, return, do a batch of bytes in PIO or 
- * 'hardware handshake' mode upon DRQ).
- * If you plan on changing this (i.e. to save the esp_status register access in 
- * favor of a VIA register access or a shadow register for the IFR), make sure
- * to try a debug version of this first to monitor what registers would be a good
- * indicator of the ESP interrupt.

- * OK, here's the goods I promised.  The NCR 86C01 is an MCA interface chip 
- *  that handles enabling/diabling IRQ, dma interfacing, IO port selection
- *  and other fun stuff.  It takes up 16 addresses, and the chip it is
- *  connnected to gets the following 16.  Registers are as follows:
- *
- * Offsets 0-1 : Card ID
- *
- * Offset    2 : Mode enable register --
- *                Bit    7 : Data Word width (1 = 16, 0 = 8)
- *                Bit    6 : IRQ enable (1 = enabled)
- *                Bits 5,4 : IRQ select
- *                              0  0 : IRQ 3
- *                              0  1 : IRQ 5
- *                              1  0 : IRQ 7
- *                              1  1 : IRQ 9
- *                Bits 3-1 : Base Address

- *                Bits 6,5 : Preemt Count Select (transfers to complete after
- *                            'C01 has been preempted on MCA bus)
- *                              0  0 : 0

- *                              1  1 : 7
- *  (all these wacky numbers; I'm sure there's a reason somewhere)
- *                Bit    4 : Fairness enable (1 = fair bus priority)
- *                Bits 3-0 : Arbitration level (0-15 consecutive)
- * 
- * Offset    4 : General purpose register
- *                Bits 7-3 : User definable (here, 7,6 are SCSI ID)
- *                Bits 2-0 : reserved
- *
- * Offset   10 : DMA decode register (used for IO based DMA; also can do
- *                PIO through this port)
- *
- * Offset   12 : Status
- *                Bits 7-2 : reserved

- *                Bit    0 : IRQ pending (0 = pending)
- *
- * Exciting, huh?
