SCSI HDD.

[Tien]

I tried to mount a SCSI card and 4G HDD on my P3BX Gigabyte board but it didn't work. How can I do that and if it work I don't know if the SCSI HDD will work with my current IDE 15G HDD or not?

Thank you.

How is the boot sequence set in BIOS setup?

Which SCSI -- wide, ultra wide, etc?

Does drive need to be terminated?

I tried to install the SCSI card and HDD in a old Deskpro 466 Compaq system and it worked well. During the boot process I got the following message:

SCSI ROM BIOS for 18C30/18C50/1800 V3.5.
(C) 1993, 1994 FUTURE DOMAIN CORP.

Sanning controller 0...

ID0 Seagate ST34520W Firmware ver. 1Q09 (FS).

Then I tried to do that again in the Gigabyte board system without any drives attached. The system could not detect anything. Then I tried to install it with my current IDE HDD, The system only detected the IDE HDD. I also changed some in the Boot Sequence item in the AWARD BIOS but I got no way. I thought my new system doesn't support or can't work with my old SCSI card. It is ISA slot-SCSI card with 50 wires-SCSI cable. I'm sorry but I don't know the drive need to be terminated or not.

Usually with SCSI (Small Computer Systems Interface) both ends of the SCSI chain have to be terminated with a resistor that tells the SCSI controller "this is the end of the line." You can use up to 8 devices,incluiding the controller. Each has a unique ID number. I think the controller is always 7, the others are 0-6, if you want the SCSI drive to boot it has to be 0. (I may be wrong on the ID numbering, controller might not have to be 7.)

Most motherboards will only boot to either IDE or SCSI, but both cannot be used unless the IDE is the boot drive. BIOS always looks for an IDE drive first. If you want to boot to the SCSI drive, go SCSI all the way and don't mix it with IDE.

Sounds like the drive may need to be terminated. Check into SCSI in the PC Guide (http://www.pcguide.com/ref/hdd/if/scsi/index.htm) , SCSI Configuration here ( http://www.pcguide.com/ref/hdd/if/scsi/conf.htm)

The last link also has articles concerning BIOS and setup issues, mixing it with IDE, Device ID...enough to keep you busy for an hour or three...notice in the article concerning Device IDs, that some drives have physical jumper or dial settings to tell the drive which ID number it has. Others use software. You'll need to find out which type(s) you're using.

As long as the drive was recognized on one system, the termination is probably OK.

It seems like the drive and the SCSI card are both good.

Install the drive and the card in the Gigabyte system.
In the BIOS setup program, change the boot sequence to SCSI first,
then C:, then A:, and power up.

If that does not work, and if you have more than one ISA
expansion slot, move the card to a different ISA slot and try it again.

If that does not work, disconnect the power and data cables
from the IDE HD, so that the SCSI drive is the only HD in the system,
and power up with a system disk in the A: drive.
