The point:
SCSI can not be activated in BIOS if SATA RAID present; OS will not
load.
The Question:
How can I have my SCSI tape drive detected without loosing my OS SATA
RAID installation?
Details:
I have a Gateway brand E-9510T server for which I lost the original OS
build on SCSI RAID. It never did accept the OS installation on SCSI so
I opted for setting up SATA RAID. I updated all firmware.
I have a SCSI tape drive I need to install but the OS is not
recognizing it due to the SCSI RAID option being deactivated, or
atleast that's what it seems to be.

No reason the BIOS has to know unless you want to boot from SCSI devices.
The kernel can find it later in the boot process.

I am not familiar with this server or controller, but there may be an option in
the SCSI bios to support tape drives. They should just show up though.

Which O/S?

Is the SCSI interface a SCSI RAID interface? Some SCSI RAID
controllers cannot deal with anthing by disk drives and then only as
RAID sets. Several of Adaptec's motherboard SCSI controllers have a
RAID daughter board option. Pull this daughter board off and you have
a plain vanila Adaptec SCSI controller. This should not interfear
with the SATA RAID controller.

I did find out that the two SCSI ports on the system board are
different. One is a 68 (Channel A) and the other an 80 pin(Channel B).
What's the difference?

80-pin connectors are found
on backplanes and drives,
not on controller cards --
80-pin devices use the same
bus architecture as 68-pin
devices, but don't have
separate power connectors,
but instead parallel the
extra 12 pins to bring in
the 12VDC and 5VDC the
devices require.
Unless you're attempting to
boot from the tape drive,
BIOS support isn't required
at all -- the tape device
driver will give the OS all
the access it needs afaik.

80 pin is SCA. Generally, this is part of a hot-swap backplane. There
aren't any actually 80 pin *cables*, unless this is a machine-specific
cable meant to go from the motherboard to the hot-swap backplane
chassis. The 80 pin connectors on the backplane carry not only the
68-pin SCSI logic, but also the power and the ID bits. A SCA (80-pin)
disk does not have either a power connector nor ID jumpers -- both are
supplied with the 80 pin connector. It is not unusual for a server box
with on-board SCSI RAID to also have a hot-swap/SCA SCSI backplane. The
backplane is often part of a chassis that includes 'slides' that hold a
disk and have a locking/unlocking level to facilitate hot swapping disks
from the front of the system without opening up the system or unscrewing
anything -- one just yanks the lever and the drive pops out. Unscrew
the old drive from the slide, screw on a new drive and shove it in and
lock it in place with the locking lever -- disk spins up and the RAID
controler sees it, etc.

Just to pick a nit, some
SCA drives have separate
ID jumpers in parallel
with the SCA connector
-- I remember the big
(1.6" height) old
IBM/Hitachi models had a
full set of them on the
front of the drive,
which can come in handy
when IDs are hard-wired
into the backplane and
you want to change one
temporarily without
taking too much apart.

You don't actually say what went wrong. To me "It never did accept the OS
installation on SCSI" sounds very much like the o/s once booted interpreted the
order of the devices differently to how the BIOS did. This can lead to weird
behaviour like the installation going through but the boot failing with various
different errors afterwards. Nor do you say what operating system you are
running so it's very difficult to be more specific about the error that you
might get in this situation.
Be more specific about the error that stopped you before and how you have it
configured now and exactly what operating system/patch level you are running.

Datawise: not much. SCA {80 pin} is 68 plus added pins for drive
power. This allowed the drives to be hot swapped just by sliding them in
place. [Obviously, the driver had to rescan to acquire the drives but...]
There are adapters to fit on the back of 80 pin drives and let you
connect a 68 pin cable to it.
