Linux runs fine with the Adaptec 2740 EISA SCSI controller.  Glancing through
the kernel sources I find:

/*
 *      eata.c - Low-level SCSI driver for EISA EATA SCSI controllers.

[...]

 *  This code has been tested with up to 3 Distributed Processing Technology
 *  PM2122A/9X (DPT SCSI BIOS v002.D1, firmware v05E.0) eisa controllers,
 *  no on board cache and no RAID option.
 *  BIOS must be enabled on the first board and must be disabled for all other
 *  boards.
 *  Support is provided for any number of DPT PM2122 eisa boards.
 *  All boards should be configured at the same IRQ level.
 *  Multiple IRQ configurations are supported too.
 *  Boards can be located in any eisa slot (1-15) and are named EATA0,
 *  EATA1,... in increasing eisa slot number.
 *  In order to detect the boards, the IRQ must be _level_ triggered
 *  (not _edge_ triggered).
 *
 *  Other eisa configuration parameters are:
 *
 *  COMMAND QUEUING   : ENABLED
 *  COMMAND TIMEOUT   : ENABLED
 *  CACHE             : DISABLED
 */

Does the kernel detect the SCSI controller during boot?

work's with a DTC-3x92(EISA/SCSI2) controller...
 after an upgraded BIOS that emulates an aha154x;
  this is NOT a reccomendation.

I use an Adaptec 1740 host and a VLB-IDE controller. I sold my
Ultrastor 34f to get the 1740. I was hoping to improve my
interrupt over head, particularly vlb bus video contention, as my
mouse seemed sluggish while compiling in X. I'm quite happy with the system
now.

Runs fine here, but I'm using a BusLogic 742 controller, not a DPT...

Uh, the DPT drivers are alpha and are *not* built into the kernel.  I
also have an EISA DPT and am waiting for a friend to build me a boot
disk with the alpha drivers.  But I sure wish they were not alpa.
