SCSI... Ugh!!! Help me pleaseee..!!!

[Xtremist]

Man alive. Me and SCSI have this wonderful love/hate relationship...

Anyway, first my hardware:

Adaptec 2940UW PCI SCSI Adapter
Plextor 40X UltraPlex Wide CD-ROM
Seagate Barracuda ST32550N 2.1GB SCSI HDD

Oookkk... So I just have the SCSI card and CD-ROM installed in my system. Everything works 100% perfectly. I add the HDD in and everything looks good when it starts to bootup. But then it just freezes halfway while it's booting! Before I had the SCSI card installed, it would bootup into windows (I currently have two IDE HDD's as well) but then freeze when I'd try and install the SCSI host driver. After unplugging both devices from the controller, it installed fine. I then plugged ONLY the cd-rom in and it works. Add the HDD and screws up again... BTW, the cd-rom is internal 68-ping and the hdd is internal 50-pin... I don't really know what else to say, but I really really need some ideas!

Oh, SCSI ID for cd-rom is 3 and for hdd is 0... I believe the controller is 7? Thanx!

did you go into the bios of the board and make the boot- up order scsi, floppy, etc, instead of drive 0, floppy?

 

[Xtremist]

I did... I put it to SCSI, C, A and SCSI, A, C as well. No difference. I'm not really trying to boot up with the SCSI drive just yet (although ultimately I want it as my OS/app drive).

For some reason I have a feeling it has something to do with the termination. Either termination of the bus OR the power... I'm not sure which, or if any though...

Check your SCSI BIOS and see if booting from a SCSI device is enabled, and check that the proper device id is specified. As far as termination, the card should provide its own. The last device on the cable should be terminated, whether it is the CD or the hd. On the drive, the top label should give you proper jumper settings. Make sure that the drive power spins up. If not try jumpering it for motor spinup.

The thing is, I'm using TWO intenal cable's... And so I'm currently terminating both the cd-rom AND the hdd... But I'll try those ideas... thanx

You have to make sure both cables have termination enabled. Set the hard drive to ID0 and the CDROM for ID1, the card should be ID7 (default)

Make sure parity is also enabled and term power is set in the SCSI card. from there, only thing I can think of is the command queue depth may be wrong.
