Multiple NCR host adapter detection problems.

Multiple NCR host adapter detection problems.

Post by Joop Carel » Sun, 31 Dec 1899 09:00:00



Hello,

I have a system with three scsi adapters. One is an AIC7800 (Adaptec) UW

controller, which runs most of the important stuff.

But, as the result of some 'gifts' from third parties, an amount of more
or less
'legacy' hardware became available. In order to use this hardware I
required
two more scsi adapters. I chose to insert two NCR-810 adapters.

The funny part is that the kernel seems to detect the two host adapters,
but
refuses to scan both buses for devices. Here's a part of my dmesg:

ncr53c8xx: at PCI bus 0, device 19, function 0
ncr53c8xx: 53c810a detected
ncr53c8xx: at PCI bus 0, device 11, function 0
ncr53c8xx: 53c810 detected
ncr53c810a-0: rev=0x23, base=0xffbefc00, io_port=0xfc00, irq=19
ncr53c810a-0: ID 7, Fast-10, Parity Checking
CACHE TEST FAILED: timeout.
CACHE INCORRECTLY CONFIGURED.
ncr53c810a-0: detaching...
ncr53c810-0: rev=0x02, base=0xffbef800, io_port=0xf800, irq=16
ncr53c810-0: ID 7, Fast-10, Parity Checking
ncr53c810-0: restart (scsi reset).
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.1.20/3.2.4
       <Adaptec AIC-7880 Ultra SCSI host adapter>
scsi1 : ncr53c8xx - version 3.2a-2
scsi : 2 hosts.

There are a couple of scary points here:
1) The errors about the cache
2) The remarks about 'detaching', whatever that might mean, and
3) The fact that Linux reports "2 hosts", while it needs to detect 3.

Does anybody have any thoughts on this one?

Joop Carels,

The PCI-Howto says that there might be a jumper on the NCR 53c810's, to
tell the cards whether there are one or two of them.

It looks like these are two slightly different cards (but I don't know
if this could bring up this problem).

You see those last three lines?

I'd bet anything that card's just plain defective. Does it have an on-board
BIOS?

Can anyone help me out here? I'm trying to install
Linux on a SCSI box with a NCR 53C810 adapter but
both Mandrake6.1 and SuSE fail to recognize it.
I tried entering 'parameters' but the manual
is as clear as mud as to what to type. Autodetect
also fails.
Hope you can help

Hmm, I'll have to check on that one by inserting each card individually.
Shouldn't be that much of a problem though, but it will have to wait until
after the Xmas holidays.

What I did try was swapping the flatcables, but that only proves the first
one (whichever physical one that is) works.

Regards,
Joop.

 
 
 

1. TP4XE and NCR-Host-Adapter, was: asus P55TP4EXPB 24Mb serious problems

 * Newsgroups: comp.os.linux.hardware,comp.os.linux.misc,comp.os.linux.setup

Indeed...

I tried 4 pairs of different single-sided 8 MB PS/2 SIMMs, no one worked.
No with 4 Pcs. of 4 MB single-sided 4 MB SIMMs the problems are gone.

Now something completly different:

Has anyone discovered problems with no-name NCR PCI SCSI-Adapters and the
TP4XE?

My Adapter works fine with an "old" dual-pentium board (intel Neptun
Chipset) but in the PT4XE Motherboard it doesn't detect any device.

Greetings, Matthias
