25 * The card is detected and initialized in one of several ways :
26 * 1. Autoprobe (default) - since the board is memory mapped,
27 * a BIOS signature is scanned for to locate the registers.
28 * An interrupt is triggered to autoprobe for the interrupt
29 * line.
30 *
31 * 2. With command line overrides - t128=address,irq may be
32 * used on the LILO command line to override the defaults.
33 *
34 * 3. With the T128_OVERRIDE compile time define. This is
35 * specified as an array of address, irq tuples. Ie, for
36 * one board at the default 0xcc000 address, IRQ5, I could say
37 * -DT128_OVERRIDE={{0xcc000, 5}}
38 *
39 * Note that if the override methods are used, place holders must
40 * be specified for other boards in the system.
41 *
42 * T128/T128F jumper/dipswitch settings (note : on my sample, the switches
43 * were epoxy'd shut, meaning I couldn't change the 0xcc000 base address) :
44 *
45 * T128 Sw7 Sw8 Sw6 = 0ws Sw5 = boot
46 * T128F Sw6 Sw7 Sw5 = 0ws Sw4 = boot Sw8 = floppy disable
47 * cc000 off off
48 * c8000 off on
49 * dc000 on off
50 * d8000 on on

27 * The trantor boards are memory mapped. They use an NCR5380 or
28 * equivalent (my sample board had part second sourced from ZILOG).
29 * NCR's recommended "Pseudo-DMA" architecture is used, where
30 * a PAL drives the DMA signals on the 5380 allowing fast, blind
31 * transfers with proper handshaking.

35 * Note : a boot switch is provided for the purpose of informing the
36 * firmware to boot or not boot from attached SCSI devices. So, I imagine
37 * there are fewer people who've yanked the ROM like they do on the Seagate
38 * to make bootup faster, and I'll probably use this for autodetection.
