Dear technical support people,

After the last two mails I sent (on Jan 14 /Jan 16), there were no
answers from you. (Your usual reply time appeared to be two days, not
including weekend). In case the mails got lost, I will repeat the
problem. In addition to this, I'll send it to the linux-SCSI mailing
list just in case somebody solved the problem before and is able to
help me.

I have a GigaByte GA-486AM PCI mainboard and trying to use a Symbios
Logic / NCR 8250S SCSI Hostadapter with SDMS 4.0 / NCRPCI 4.01.00.

At Bootup the Hostadapter BIOS tells me, it's SDMS 3.0 / NCRPCI 3.06.00
(or 3.07.00, I don't boot very often.)

A short summary of the answers from you is:

1) Technical support at Symbios told me to turn off SCSI BIOS in the
   mainboard BIOS setup.

2) GigaByte technical support told me, a well-designed hostadapter will
   ignore the mainboard BIOS.

ad 1) : There is no such option in the mainboard BIOS setup. I use the
latest version (4am1107.bin) of the BIOS.

ad 2) : Is this right? Gigabyte tells me, Symbios cannot produce
well-designed PCI to SCSI hostadapters?

My situation: I did not know, that the SDMS BIOS is included in the
mainboard BIOS. The manual didn't tell me.

The BIOS ver. 4.0 of the adapter was one of the reasons, why I bought
it. I wanted to be able to do rearranging of SCSI and NON-SCSI disks,
and, of course, wanted to have the enhanced performance that the SDMS
4.0 BIOS provides. (If I read the right source, this is scatter/gather
for example).

What can I do to get the SDMS 4.0 BIOS up and running? (I use DOS,
Windows, OS/2 Warp and Linux).

 Regards,

    Dirk Försterling
