Hello Juan,

Not being one to split hairs (well, ok .. I AM one to do that ...) your
terminology isnt correct. When dealing with SCSI drives, there is no
Master/Slave relationship between them. They each need unique SCSI ID's.
Based on the infomration you have provided, it appears that you have 2 disks
that are trying to be SCSI ID:0 . This isnt good. the disk with the ID of 0
is typically the drive that the system boots from.

Arrange your SCSI ID jumpers as follows, and you should be in good shape:

Atlas: no jumpers for ID's (SCSI ID = 0 , Boot Drive)
Fujitsu: jumper ID1 (SCSI ID = 1)
Refurb: jumper ID 0 and 1 (SCSI ID = 2)

In additon, if you are still having problems, make sure that the MTR Start
jumper (very small on the PCB) is jumpered as well.

Let us know how this works out for you,

Hello Group.

I have a Compaq Professional workstation SP700 which is currerntly working
well with 2 Compaq SCSI hard Disks. I am in the need of installing a new
quantum Atlas Hard Disk.that I bought recently. I have been playing trial
and error but I am not able to make at least the BIOS recognize the

Quantum
Atlas hard Disk.


I am not sure if this newsgroup accepts attachments, so I am going to give
you a my scope of the subject and if needed, I will email you the scanned
tags of the Quantum Atlas hard Disk in Jpeg format as well as an
ilustration of the jumpers and how they are curently set, in a PDF format.
B.T.W, I already went to Quantum website (but without luck) so I am still
in base #1.

These is the Jumper set in the two Compaq Hard Disks:

Compaq (Fujitsu) Compaq (Refurbished disk)
Wide Ultra SCSI 2 Wide Ultra SCSI 2
Boot Disk Slave Disk
10,00 RPM 7200 RPM
9.1 GB 9.1 GB

And this is the jumpers currently unselected in the Quantum Atlas Hard

Disk.
As I say, My goal is to make this new HD the Master and the other two ones
slaves; say the 10 RPM as Slave 1 and the 7.2RPM as the second slave.

I really appreciate any help that you may give me in order to make this
three disks work in my Compaq SP 700

Thanks and have a nice week!
