Very Computer

        Perhaps there is a specific SounBlaster / Adaptec 1542 problem.
Some time ago, I have posted a similar message but it was in another
newsgroup and I not had any response yet.

        I attach a copy of this past message. In case of an email response to
John, please cc to me also.

Thank you very much for your help,

Subject: SB AWE-Adaptec 1542 conflict. Why?
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Status: R

Hi everybody,

As the subject line tells, it seems that I am experiencing a conflict
between
the SoundBlaster AWE32 PnP and the Adaptec 1542 SCSI adapter.

A detailed description of my equipment is given below. However, briefly,
I have an Adaptec 1542 (with an attached Plextor 8x cdrom) and a SB AWE.
Separately, both cards works well. According to my vendor the
combination also
works well with Windows NT but of that I have no personal experience.
Now, the problem arises when, the AWE being in service, that is after
the command:

/sbin/isapnp /etc/isapnp /etc/isapnp.conf

is issued, I want to use the cdrom :

mount /dev/scd0

In this case, I get repeatedly the following messages:

--> aha1542_out failed (2) scsi aborting command due to time out :
           pid 17424, scsi 0, channel 0, id 4,lun 0, 0x1e 00 00 00 00 00
--> scsi host 0 abort (pid 17424) timed out - resetting
--> scsi host 0 abort (pid 17424) timed out - resetting
--> scsi is being reset for host 0 channel 0
--> aha1542_out failed (2) sent BUS DEVICE RESET to target 4
--> sending DID_RESET for target 4

... and so on ... until I hit the reset key --- cann't do anything
else :-(

This does not depend upon whether or not the sound module is loaded and
this
does not depend upon whether I boot kernel 2.0.14 or 2.0.22.

As it can been seen from the following detailed description , the
Adaptec and the
SB do not share the same IRQ or the same ioport address or the same dma
channel.

If anybody has an idea that would help me a lot,

Thank you very much for your help,

Here is the detailed description of my equipment. It is rather long;
this is
because I cann't figure out what is important. I thought that only IRQ,
I/O
port, and DMA channel were important. Obviously, this is not true.
