Hello,

  (Before continuing, it may be important to know that my motherbaord has an
onboard adaptec AIC7xxx controller which controls my primary hardrive, tape,
and CD drive - everything there works fine)

  I am trying to add two Adaptec AHA1740 SCSI EISA controller cards to my
system.  I have set the cards through the EISA setup (bootable configuration
disk that came with system) as follows:

EISA slot #3:
    Interface Mode: Enhanced Mode
    I/O Port Definition: Disabled (Enhanced Mode)
    DMA Channel Definition: Disabled (Enhanced Mode)

    SCSI Device Configuration: Enhanced mode configuration

EISA slot #4:
    Interface Mode: Enhanced Mode
    I/O Port Definition: Disabled (Enhanced Mode)
    DMA Channel Definition: Disabled (Enhanced Mode)

    SCSI Device Configuration: Enhanced mode configuration

  I can only use the above addresses for the host adapter BIOSes since I
also have a Specialix RIO card in the system which apparently uses all of
the DXXXH address space - the configuration program will not let me use any
other addresses for my SCSI controllers other than the ones shown above.

  When the machine boots up, I see both controller's BIOSes and the drives
connected to them come up (I have 6 identical drives - 3 on each
controller):

.Adaptec AHA-1740 BIOS v1.40
.Copyright 1992 Adaptec, Inc.
.[Enhanced Mode]

.Target 0 - QUANTUM FIREBALL540S          - Drive D: (81h)

.Target 2 - QUANTUM FIREBALL540S

  Then (on a * RH7.0 install) I invoke the command:
'insmod /lib/modules/2.2.16-22/scsi/aha1740.o'
and get the following messages:

.Configuring aha174x at IO:3c80, IRQ 11

. sdd: unknown partition table

  I was then able to 'fdisk' these three devices and setup the partition
tables on these drives.  So, now the above "unknown partition table" lines
read:

. sdb: sdb1
. sdc: sdc1
. sdd: sdd1

  So, now my questions are these:
1)  What does "Extended translation disabled" mean above, and is it a
problem?
2)  Does the "unable to allocate IRQ for adaptec controller" refer to the
second controller that I am not able to access?  (which is shown above as
using the same IRQ as the first one - IRQ 11).  But, the EISA setup program
does not give IRQ choices for 'Enhanced Mode'...

  As a note, these were working in the same box while running the SCO
Openserver O/S.  However, I had these cards set to 'Standard Mode' (instead
of 'Enhanced' - I read that Linux supports the AHA1740 in Enhanced Mode).
Therefore, on the SCO setup I had the IRQs set to 9 and 10, the I/O Port set
to 130H and 230H, the DMAs set to 7 and 6, and the adapter BIOSes disabled
(there was disk array software controlling these cards).  So, there were
enough IRQs before, and I have not added any other cards to the box since
switching to Linux... actually, I removed an AHA1740 card that used to
control the boot drive for SCO (the onboard AIC7xxx controller wasn't used
under the SCO configuration).

  Any help or direction on this would be highly appreciated.

Thanks in advance!

  Please disregard question 1), the message must refer to the "Extended BIOS
translation" that I set to 'Disabled' through the EISA setup for the cards -
and shouldn't matter... all the drives on the controller are less than 1GB
(they are all 0.5GB drives).

But, I still need the answer to question 2) please!

This is not a problem for *Linux*.  If you were booting from these disks
and they were large enough to have more than 1024 cylinders, LILO would
be unhappy (unless they were partitioned to have a /boot or / partition
whole under the 1024 cylinder limit).  MS-DOS would be unhappy if the
disks were large.  Since none of this applies, this is no big deal.

It appears that Linux will support ONE AHA1740 in Enhanced Mode, but
not two...  You should either set one (or both) cards to 'Standard Mode'
and use different IRQ's for the two cards...

  Thank you very much for your suggestion.

  I recently tried setting both cards to Standard mode, using the same
settings as they were configured (and working) on the SCO system.

  However, I had read the source code 'aha1740.c' and apparently this driver
only works for these cards operating in Enhanced Mode.
  I also read the Adaptec manual for the 1740 cards which explains why.  It
said that "Standard Mode is an AHA-1540/1542 compatible interface that
allows the use of AHA-1540/1542 software drivers.  Enhanced Mode is a higher
performance interface that uses AHA-1740 software drivers".
  So, I tried setting both cards to Standard Mode and used the 'aha1542.o'
driver module invoked by the 'insmod' command and this is what I got:

scsi : 1 host.
/lib/modules/2.2.16-22/scsi/aha1542.o : init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including
invalid IO or IRQ parameters

  Any other suggestions?

Thanks again,
  Scott Navarre

  One other note:  The header comments at the top of 'aha1740.c' says
"Multiple adapter support"...
