README file for the Linux DTC3180/3280 scsi driver.

by Ray Van Tassle (rayvt@comm.mot.com)  March 1996

Based on the generic & core NCR5380 code by Drew Eckhard



SCSI device driver for the DTC 3180/3280.

Data Technology Corp---a division of Qume.



The 3280 has a standard floppy interface.



The 3180 does not.  Otherwise, they are identical.



The DTC3x80 does not support DMA but it does have Pseudo-DMA which is

supported by the driver.



Its DTC406 scsi chip is supposedly compatible with the NCR 53C400.

It is memory mapped, uses an IRQ, but no dma or io-port.  There is

internal DMA, between SCSI bus and an on-chip 128-byte buffer.  Double

buffering is done automagically by the chip.  Data is transferred

between the on-chip buffer and CPU/RAM via memory moves.



The driver detects the possible memory addresses (jumper selectable):

	CC00, DC00, C800, and D800

The possible IRQ's (jumper selectable) are:

	IRQ 10, 11, 12, 15

Parity is supported by the chip, but not by this driver.

Information can be obtained from /proc/scsi/dtc3c80/N.



Note on interrupts:



The documentation says that it can be set to interrupt whenever the

on-chip buffer needs CPU attention.  I couldn't get this to work.  So

the driver polls for data-ready in the pseudo-DMA transfer routine.

The interrupt support routines in the NCR3280.c core modules handle

scsi disconnect/reconnect, and this (mostly) works.  However.....  I

have tested it with 4 totally different hard drives (both SCSI-1 and

SCSI-2), and one CDROM drive.  Interrupts works great for all but one

specific hard drive.  For this one, the driver will eventually hang in

the transfer state.  I have tested with: "dd bs=4k count=2k

of=/dev/null if=/dev/sdb".  It reads ok for a while, then hangs.

After beating my head against this for a couple of weeks, getting

nowhere, I give up.  So.....This driver does NOT use interrupts, even

if you have the card jumpered to an IRQ.  Probably nobody will ever

care.
