NCR53c90a SCSI (I've read the SCSI Howto)

Post by david gree » Wed, 14 Aug 1996 04:00:00

A while back, someone gave me a Wangtek 5525ES SCSI Tape Drive.  I've
been looking for a controller, and now this person is willing
to give me the board from his old computer that he used with
the drive under DOS/Windows.

Both the drive and the controller use the NCR53c90a chip.  In
the HOWTO, this snippet disturbed me:

SCSI hosts that will NEVER work :

Non Adaptec compatable, non NCR53c8xx DTC boards (including
the 3270 and 3280).

The board itself has a "Compaq" label on it (I assume this person
used a Compaq).  I have not seen the board yet, but from what I
was told, there is no "DTC" label on it.  Can anyone tell me if this
will work under Linux?  Or is this board a DTC product with "Compaq"
on it?  Are there any drivers for the 53c90a?

If it won't work, I'll just trade in the controller at a used
parts store.  Will I have to trade in the drive too?

If it will work, I'll need some help with jumpers, etc. since there
are no manuals.

Thanks in advance for any help!

1. If you've got DPT SCSI, please read!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

        I am interested in setting up Linux on my 486DX/4 120 w/ 16mb
RAM and a DPT 2021 ISA SCSI board.  I've got 2 HD's on it now, but will
add a drive for Linux.  I need to know 2 things:

1. Which CDROM version of Linux can be ordered that will let me use
   my DPT SCSI board?

2. Is it possible to have both Linux and Win95 on the same system?  Note,
   I will have 3 drives.


2. HW Compatiblity: SCSI HD, controller, SVGA.

3. Svgalib Questions (and yes I've read that HOWTO _and_ I'm a newbie)

4. Sparc 20 FS

5. SLS can't detect my SCSI disks. Why? (I've read SCSI-HOWTO)

6. gdm chooser font

7. SCSI read works, SCSI write doesn't

8. K6-2 300 works great!

9. I've read the howto and the rest...

10. I've read/am reading the faq's - but what is a Segmentation fault?

11. retry: howto debug scsi.c on a scsi only system?

12. SCSI Zip (DB25 to 68pin 'SCSI-3')

13. I think I've found a 1.1.4x scsi problem.
